Recently, I have been having trouble with Nvidia drivers following a kernel update in Linux Mint (21.1 is the version that I am using). The kernel version has been rolled back from 5.19.x to 5.15.x, and I installed an old AMD graphics card as well. Things still are not perfect, though, so I will be looking out for a way to make things smoother. For now, all is good enough for the moment.

Google Analytics appears to be losing favour in the EU, if Matomo is to be believed. First, Austria outlawed its usage and no France follows suit. This naturally suits Matomo, a self-hosted open-source alternative for collecting website metrics, so it should not be any surprise that they are forthcoming with these details.

After seeing messages like “The authenticity of host ‘hostname’ can’t be established” during ssh connections, I decided to investigate more and came up with the following solution:
sudo chown -v $USER ~/.ssh/known_hosts
My known_hosts file had gained root ownership so i could not write to it so changing the ownership to that of my own user account sorted the problem. An alternative could be to change the group assignment using chgrp and setting permissions using chmod but what I did sufficed for my needs.

Here is a way to recursively delete folders and their contents in PowerShell:
Remove-Item .\foldertodelete -Force -Recurse
The Force switch silences any messages that otherwise would appear and the Recurse switch is what gets directories removed.

Devuan (pronounced like dev-one) is a fork of Debian that does not use systemd as Debian, like so many other distros, is doing. Part of the name must come from a collective calling itself Veteran UNIX Admin (VUA). There is no actual release just but one is intended for around the same time as Debian 8.0 gets released and donations are being solicted via the website.

When a VirtualBox upgrade broke the networking on a Windows 8.1, it was time to look at System Restore to see what it would do. It reverted version 4.3.20 to 4.3.15 and the network disconnection stopped. For now, I will remain with that older version after the misstep with the latest one. Sometimes it is best to stick with what is known to work.

With my deciding to try doing about my waistline during the summer (a bike got put on a trainer and around 30 minutes is spent on it most evenings while I also catch up some reading; now, I feel fitter and incursions into the countryside have an added air of confidence about them), an interest in fitness monitors has developed and the Pulse Ox from Withings has taken my eye due its being price of around £100. That makes it less than alternatives and it isn’t the only health gadget that the company does either with there being a blood pressure monitor in its range too. The Pulse Ox monitors such things as heart rate, activity such as walking and running, sleeping and weight too. It should work with your smartphone as well, which is a bonus. It is one of several like it with Samsung and Apple going in for phone apps and Microsoft releasing their Band device as well. This appears to be a growing area where I never expected to see mainstream technology companies having a role for themselves.

Here is the test for the “Shellshock” vulnerability in the bash shell:
env x='() { :;}; echo vulnerable’ bash -c “echo this is a test”
It should not return the following:
vulnerable
this is a test
This would be acceptable:
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x’
this is a test
Also, just having this might be fine too:
this is a test
In case you need it, Redhat has more information on the bug that caused scare stories everywhere. Now, it is over to system administrators everywhere to do their bit now that bash has been patched.

Sometimes you need to create more than one directory level in a hierarchy at once and mkdir has the -p option for this purpose. That gets it to create any missing levels in a folder path and avoids warnings that would be issued otherwise.

Debian 8 is under development and has its first beta ready for download. XFCE is now the default desktop environment though it remains possible to install GNOME and GNOME Shell too. In fact, I successfully have given that a go in a VirtualBox installation and will keeping an eye on development so long as no system meltdowns occur. The version of the X Window system already is incompatible with VirtualBox 4.3.14 so we need to await a new version of the virtualisation software before we get access to advanced functions like full window desktop expansion. What we have at the moment works well enough to keep eye on development so we can wait for that full support.

Perfect Resize from onOne Software caught my eye for scaling up images after seeing it mentioned in a Outdoor Photography review of Avanquest PhotoZoom Professional. With a library of 6″ x 4″ prints, I am limited in how large I can make scanned images without they looking blurred and pixelated so that’s why my interest was aroused. There may be a free moment spent seeing what it might do in that situation yet.

Nvidia has a useful page on the difference between DVI-D and DVI-I. It came in handy when transitioning from VGA to DVI on my home PC’s. That made what appears on my Iiyama screen much sharper and allowed me to rid myself of a suspect VGA cable too.

Here are some interesting articles about EFI and UEFI that I uncovered during a recent episode of setting up dual booting of Windows 8.1 and Linux Mint 17 on a PC with EFI:

In the U.K., BT allows you to divert your phone calls for a fee and I have made good use of it over the past year. The service is called Call Diversion and Eircom, Ireland’s counterpart to BT, offers Call Forwarding in Éire. Both are handy because redirecting a call to a mobile phone means that you know you are not missing any calls and that there is nothing lurking on an answering machine when you do get to your home or office. Landline telephony may seem less exciting these days than other forms of communication yet it still has its place and I would not get any nasty surprises along the path of life either. If only I had started doing this kind of thing earlier than I did…

Here’s a useful article about the ever useful locate command. Whether it is FreeBSD or Ubuntu that you are running, this article has a use and that especially when the locate database needs updating with the updatedb command.

A recent website redesign was well helped by modern.IE‘s collection of virtual machine appliances containing different versions of Windows and Internet Explorer. Depending on the host operating system that you are using, you have different options. For Linux, it is VirtualBox only while Windows gains VMware and Virtual PC too. It is a matter of just picking out what suits your situation from dropdown lists.
The first one that I picked was Vista with IE 7 and it was an interface that I had not seen for a while. For all the criticism, the operating system did work well though I wonder if it arrived before the computer hardware that it really needed in order to run smoothly. The dark theme cannot have helped its cause either, especially when compared with the much brighter Windows 7 or Windows 8.x. A Windows XP appliance with IE 6 was grabbed before it gets yanked and support for the elderly OS does finish in April. IE 6 probably is on its last legs so I probably can ignore it now but IE 7 might live longer yet. Window 7 appliances with IE 9 and IE 10 also were downloaded and confirmed that all was well in recent versions of IE when it came to the website. The Vista virtual machine allowed me to ensure that all looks acceptable on IE 7 too. The VM’s themselves contain evaluation versions of enterprise variants of Windows and have a limited lifespan though it is little trouble to reimport an appliance again to rest the clock if so required. In most cases, you extend the evaluation periods too through re-arming and there only are so many times that you can do that anyway. With Windows 8.x, it isn’t even a possibility anyway.
22:05 March 9, 2014
Today, I found an interesting article on CSS media queries and put it to some use for a website redesign that has been keeping me busy over the weekend. Twitter’s Bootstrap came in handy for this too. Now, it’s on to ridding the new design of any rough edges that remain in there. That can be an ongoing task and the site is here if you fancy a look to see what my efforts have produced.
16:20 February 26, 2014
Adding a new Zalman ZM450-GS power supply did little to sort the buzzing in my speakers but it has made the PC where it was installed so much quieter; a much larger fan spinning slower helps while still moving the required amount of air. It is 450W too and I am wondering if my main PC would benefit from a similar upgrade. That may be quieter than the other one was but the case was not a deluxe model so the change should do no harm. As for the speakers, moving them was the only way to get rid of the buzzing. Looking back on this now, it seems that one of them was far too close to a PC.
20:33 February 15, 2014
Currently, the spare PC appears to be causing buzzing on my main PC speakers and with my landline telephone when it is placed right under these. Removing it helps to cut it down but I fancy having a better fix and am wondering if a new power supply might help. Also, I am wondering if there are other sources too. In the meantime, I would like to share an article on the subject that I recently found: Kill Studio Hum and Buzz at the Source.
22:14 February 12, 2014
Applying latest set of updates to LMDE worked to get to Update 8 worked smoothly unlike some predecessors. This brought the latest version of Cinnamon so GNOME now is redundant. It will be interesting to see where things go next.
16:24 February 8, 2014
During the week, I discovered that Twitter is not a benign place to go ruminating. A sharp riposte in an unnecessary tone of voice was enough to bring on a sense of extra caution. Wherever you get humanity, you are likely to encounter and one had a go at me so some thoughts are going to be kept away from there from this point forward. Sometimes, you own website is a far better place to go ponder happenings in the world around you. After all, an ugly comment can be deleted and a rogue IP address blocked if things need to go that far. Of course. more civility would be best. Polite correction is the best course whenever it is warranted since we all are human and no one is beyond making mistakes.
16:15 February 8, 2014
On my outdoors website, I have been using a PHP script from Detect Mobile Browsers but this does not distinguish between Android running on a tablet and that running on a phone. Therefore, I have turned to another source of such scripting and that is working better so far. In fact, this offers more than just PHP but also Python, JavaScript and other scripting languages along with configuration files for web servers too. Apache, Nginx and IIS all have something for them. The logic essentially is based on Perl regular expression matching of user agent strings, not an infallible means but good enough for me along with a smattering of responsive design.

For anyone lost when faced with the changes Microsoft brought in with the launch of Windows 8 and largely retained in Windows 8.1, TechRadar has a useful article: 62 Windows 8 tips, tricks and secrets. What will prove especially interesting is where Microsoft goes next when many of their customers prefer the Windows 7 interface and are sticking with the elderly Windows XP. You only can get so far by telling your customers that they are wrong all of the time and the is competition in the form of Apple’s OS X and Google’s Chrome now.

TechRadar has a round-up of Best free photo editing software: 10 top image editors you should try. Usual options like GIMP, Paint.Net and IrfanView get a mention along with other less well known ones. Interestingly, Google’s Picasa is excluded from the list but that might be because it largely is an image file management tool even if it has some image editing capabilities too.
21:28 January 27, 2014
Late last week, I found out about the image file sorting tool PhotoSift via an article on the software. It looks interesting though I have yet to try it.
17:52 January 27, 2014
Here are some interesting reviews from TechRadar:
Best compact system camera 2014: the top models reviewed
Best tripod and camera support: 13 tested
The tripod heads review really caught my eye more than the others. After all, 2013 was the year that I got a CSC and a Manfrotto tripod has sat reproachingly in the corner far more often than it should.
19:41 January 16, 2014
Today, I spotted two interesting articles to which I want to retain links on here:
Managing the future of complex business and IT landscapes
Send large files to clients with these 8 free tools
Both of these ring bells for me for different reasons. The first is a reminder of a slow and painful system project with which I was involved and of an ineffective IT support service that pained us at the time. The second is ever present in my current job with its need to send data and output files to clients as well as receiving specifications from them.

In recent weeks, I have been having trouble with the onboard network controller on a spare PC that I have at home. It connects to the network fine for a few minutes and then struggles. Making use of an old PCI ethernet card that I had from another machine solved the problem. Does anyone know of issues with ASRock motherboards and onboard network ports at all? It isn’t something that I have seen before and this motherboard never had good networking capability as long as I have had it.

After Christmas, I took delivery of an HTC One mini mobile phone that I got free as part of a contract renewal with O2. It also is known as the M4 and I have been getting used to it since I got it. A lot is familiar and there are some little differences too. Some of these leave me asking why what worked well before got changed to something that is less smooth. Of course, that can be the course of things and it applies to buying a new car as much as getting a phone upgrade. All in all, the phone works well and battery life appears much improved over the HTC Desire S so far, never a bad thing to notice.

This morning, the hosting provider for this website had an outage that lasted over three hours. The provider was Fasthosts and the cause was a power failure. They usually are good so this thankfully does not happen too often. However, we have been getting a lot of stormy weather crossing Britain and Ireland this winter so I suspect that there should be little in the way of surprise when something like this happens. Weather is not due to settle during this month so there may be more power failures, hopefully elsewhere, before things settle down again.

On one WordPress website that I have, the refresh rate for RSS widgets wasn’t the quickest and the remedy was to add this line into the themes functions.php file:
add_filter( ‘wp_feed_cache_transient_lifetime’, create_function(‘$a’, ‘return 600;’) );
It creates a custom function that is attached to the widget and the refresh time is set to 600 seconds or 10 minutes. So far, this seems to be doing what I needed.

What I didn’t realise is that TRIM currently is not enabled in Ubuntu by default. That is set to change in Ubuntu 14.04 and here is some advice on the matter until then.
20:41 December 14, 2013
This weekend, I had visions of needing a new hard drive when all files on one in my main home PC (runs Ubuntu GNOME 13.10 64-bit) went read only. The cure was to re-seat the SATA cables and all was well again. Sometimes, inexpensive remedies are best and I need not to forget this one.
20:54 October 29, 2013
Here are two interesting articles that I spotted: the first is on new features in GNOME 3.10 and the second about getting DRM-protected Flash media playing on Ubuntu 13.10. For now, I am sticking with Ubuntu GNOME 13.04 in spite of a pop-up dialogue encouraging an upgrade to 13.10; the potential for even a little disruption is something that I am delaying for now.
20:34 October 16, 2013
While editing a file in Nano on an virtual Arch Linux web server that I have, I noticed that a file had DOS newline characters instead of UNIX ones so conversion using the dos2unix command was in order. There is more on this to be found on nixCraft and there are other options such as sed described in there too.
21:51 September 7, 2013
Following a look at Webmin, I have to say that it seems a worthy tool for remote management of servers. My trial so far has been on my Ubuntu virtual web server and it works on port 10000 without interfering with the operation of the actual web server. Being able to run system updates and deletion of MySQL databases without resorting to the command will seem a bonus for some. There’s more to it than these though and I have seen the possibility of managing virtual servers located within a real being mooted. It was an issue of Linux User & Developer than inspired me so my Linux magazine reading is seeing its uses.
20:30 September 4, 2013
Here are some interesting articles for anyone thinking about software development and its realities:
The care and feeding of software engineers (or, why engineers are grumpy)
Being an introvert as I am, this article really is something to which I can relate. Whenever I cannot get the space for undisturbed work, it takes from how I enjoy my job.
How designers and engineers can play nice (and still run with scissors)
We all have to work cross-functionally so you cannot have it all your own way…
Six reasons why the NHS National Programme for IT failed
Having been involved in system design, development and implementation myself, I have something to share that fits into the same topic area. Too many cooks can spoil a broth.
Queensland Government Bans IBM from IT Contracts
My past experiences of IBM have not been good and it wasn’t just where I worked either so this is not exactly a surprise. Service organisations need to ensure that they are sufficient responsive and flexible with empowered and enthusiastic staff who do the needful.
23:09 August 11, 2013
Vagrant and Puppet look like very interesting tools for working with virtual machines. They work with VirtualBox or VMware’s Fusion and Workstation so there’s a choice of virtualisation tool.

Crash reports have been appearing after logging into an Ubuntu session for /usr/share/hplip/config_usb_printer.py and it repeating has been reinstalling HPLIP software for my HP LaserJet 1018 printer too. Leaving the printer off until I need it would be one solution and saves some electricity too but it is best to try to sort an issue when you keep getting it. The first step was to download the latest HP software and install it. That wasn’t a complete solution so I altered the latest send_message function call in /usr/share/hplip/config_usb_printer.py from the following:
send_message( device_uri, printer_name, EVENT_DIAGNOSE_PRINTQUEUE, username, 0,”)
to:
send_message( device_uri, printer_name, EVENT_DIAGNOSE_PRINTQUEUE, ”, 0,”)
So far that alteration appears to have addressed the problem but I’ll be keeping an eye on things anyway. If you’re wondering, the inspiration came from a bug discussion on Launchpad and it was the queue clearing section of the Python script that I went and edited.
20:40 April 16, 2013
Recently, I have been having bother with WordPress Jetpack comment form submission. This was caused by the Bad Behaviour plugin and allowing cross site form submission sorted the problem. The setting to change is in Settings > Bad Behaviour on the Dashboard.

20:53 February 19, 2013
During a look at a Fedora 18 Live DVD, I found a user name was needed to get to the desktop and root did the trick for me. What I didn’t notice was an install to hard drive option for the GNOME variant that I tried. Maybe it was hidden on the desktop and not displayed. If so, it looks like an oversight.

Here’s a command for removal of orphaned packages in Arch Linux and its derivatives (CinnArch and ArchBang come to mind but there may be others):
sudo pacman -Rns $(pacman -Qqtd)
15:11 January 26, 2013
Cinnarch looks very interesting. It’s based on Arch Linux so it’s a rolling distro but has Cinnamon as its desktop environment. Currently, it’s still in beta but I am tempted to give it a go in a virtual machine.
20:55 December 15, 2012
Having decided that my ever sluggish system needed a fresh operating system installation, I set to trying to get on Linux Mint 14. However, not remembering that the disk and not the partition needs specifying for GRUB installation cost me some time. Later, adding on GNOME Shell resulted in a system conflict between MDM and GDM so I now am running Ubuntu GNOME Remix instead. All feels fresher so far though a spot bother was had with the lock screen that caused me to turn off the feature. VMware Player installed without any of the trickery needed to get in its forbear and runs without a hitch so far too. Other bits and pieces need instating yet but the basis of a refreshed computing platform is in place now.
20:56 November 19, 2012
A look at Linux Mint 14 64-bit release candidate in a VirtualBox virtual machine confronted me with irritating mouse pointer behaviour. The pointer constantly darts to the left when you need it not to do that and it seriously affects usability. The final version will be awaited to see if there is an improvement because it’s not very usable as things stand. GNOME Shell can be installed in working order after a spot of fiddling. Installing the software from the Software Store doesn’t add gnome-session as well so the command line alternative remains best:
sudo apt-get install gnome-shell && sudo apt-get install gnome-session
These two really need packaging together as dependencies. Cinnamon is looking as nice as ever and in need of a plug-in that makes virtual desktops behave as they do in GNOME, even if that’s a minority interest now.
12:07 September 30, 2012
Here are commands for adding Cinnamon to Ubuntu:
sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install cinnamon
14:39 September 29, 2012
Had a look at GNOME 3.6 in Ubuntu GNOME Remix 12.10 Beta 1 release. Not all extensions are supported yet but GNOME 3.6 only launched officially yesterday anyway. Will take a little while for those extension developers to catch up with it. No hurry in moving from GNOME 3.4 until they do so.
20:24 September 22, 2012
Picked up Netgear ethernet switcher at PC World today. Working without a hitch so far. Some network reorganisation may follow suit.
20:14 September 22, 2012
Initially, I needed to use the command “modprobe vboxdrv” to get VirtualBox going on Sabayon 10. However, there seems to be a better remedy: adding the line ‘modules=”vboxdrv vboxnetflt vboxnetadp”‘ (removing the outer single quotes, by the way) to /etc/conf.d/modules and restarting the system. That seems to have done the trick though I wonder it wasn’t added for me automatically.
13:08 September 22, 2012
Until recently, I hadn’t realised that most if not all SSD’s come in 2.5″ form factor. An extra bracket is needed for installing into 3.5″ drive bays. While tempting, this remains a nice to have upgrade for me.
20:02 September 21, 2012
Found out why my proftpd daemon wasn’t working on Linux Mint. Needed to set it as standalone and not inetd operation. It’s the ServerType setting in /etc/proftpd/proftpd.conf.
21:53 September 18, 2012
Given the site a new appearance. The cause was getting microblogging going on this page. Clashes with zeeDisplay theme and Twitter Tools made for replacements that now power what you see here. Jetpack plugin added too. All looking good to my eyes so far. More tinkering may happen yet.

Desktop swapping can be done in Ubuntu and here’s the command for Xubuntu:
sudo apt-get install xubuntu-desktop
17:22 September 15, 2012
Here’s a set of commands that I once used to get GNOME Shell going for a Sabayon 9 installation in a VirtualBox virtual machine:
su
equo install --ask linux-sources
cd /run/media/john/VBOXADDITIONS_4.1.16_78094
./VBoxLinuxAdditions.run
mv /usr/libexec/gnome-session-check-accelerated-helper /usr/libexec/gnome-session-check-accelerated-helper.bak
ln -s /bin/true /usr/libexec/gnome-session-check-accelerated-helper
Hope they have a use though VirtualBox has gone through a few versions since I discovered that these had the desired effect though the login screen behaved a little oddly. Otherwise, everything worked as it should.
14:16 September 15, 2012
Pondering purchase of NAS. QNAP TS-412 looking promising but need to think about my home networking set up first. Might need an ethernet switch but plan to look into it more first, especially with uplink capability needed.
14:11 September 15, 2012
Appearance of Sabayon 10 caused a bit of disturbance to my Sabayon installation that needed installation from a DVD to resolve. Tried GRUB repairs before the non-loading of an Nvidia kernel module caused bother. Went for old fashioned approach for sake of saving a little troubleshooting time.
13:52 September 15, 2012
This has been added using the Live Blogging plugin and it’s good for pages too, unlike Automattic’s own Liveblog plugin. Maybe they’ll add that sort of functionality in time.
With UNIX being the basis of Linux, I have a soft spot for trying out any UNIX that can be installed on a PC. For a while, I had OpenSolaris on the go and even vaguely recall having a look at one of the BSD’s. However, any recent attempt to install one of the latter, and there are quite a few around now, got stymied by some sort of kernel panic caused by using AMD CPU’s. With the return to the Intel fold arising from the upgrade of my main home PC last year, it perhaps was time to try again.
The recent release of FreeBSD 10.0 was the cue and I downloaded a DVD image for a test installation in a VirtualBox virtual machine with 4 GB of memory and a 32 GB virtual hard drive attached (expanding storage was chosen so not all the allocated space has been taken so far). The variant of FreeBSD chosen was the 64-bit x86 one and I set to installing it in there. Though not as pretty in appearance as those in various Linux distros, the installer was not that user unfriendly to me. Mind you, I have experience of installing Arch Linux so that might have acclimatised me somewhat.
Those installation screens ask about the keyboard mapping that you want and I successfully chose one of the UK options. There was limited opportunity for adding extras though there was a short list of few from which I made some selections. User account set up also was on offer and I would have been better off knowing what groups to assign for my personal user account so as to have to avoid needing to log in as root so often following system start up later. Otherwise, all the default options were sufficient.
When the installation process was complete, it was time to boot into the new system and all that was on offer was a command line log in session. After logging in as root, it was time to press pkg into service in order to get a desktop environment in place. The first step was to install X:
pkg install xorg
Then, it was time to install a desktop environment. While using XFCE or KDE were alternatives, I chose GNOME 2 due to familiarity and more extensive instructions on the corresponding FreeBSD handbook page. Issuing the following command added GNOME and all its helper applications:
pkg install gnome2
So that GNOME starts up at the next reboot, some extra steps are needed. The first of these is to add the following line into /etc/fstab:
proc /proc procfs rw 0 0
Then, two lines were needed in /etc/rc.conf:
gdm_enable=”YES”
gnome_enable=”YES”
The first enables the GNOME display manager and the second activates other GNOME programs that are needed for a desktop session to start. With each of these in place, I got a graphical login screen at the next boot time.
With FreeDSB being a VirtualBox Guest, it was time to consult the relevant FreeBSD manual page. Here, there are sections for a number of virtual machine tools so a search was needed to find the one for VirtualBox. VirtualBox support for FreeBSD is incomplete in that there is no installation media for BSD systems though Linux and Solaris are supported along with Windows. Therefore, it is over to the FreeBSD repositories for the required software:
pkg install virtualbox-ose-additions
Aside from the virtual machine session not capturing and releasing the mouse pointer automatically, that did everything that was needed even if it was the open source edition of the drivers and their proprietary equivalents. To resolve the mouse pointer issue, I needed to temporarily disable the GNOME desktop session in /etc/rc.conf to drop down to a console only session where xorg. conf could be generated using the following commands:
Xorg -configure
cp xorg.conf.new /etc/xorg.conf
In the new xorg.conf file, the mouse section needs to be as follows:
Section “InputDevice”
Identifier “Mouse0”
Driver “vboxmouse”
EndSection
If it doesn’t look like the above and it wasn’t the case for me then it needs changing. Also, any extra lines from the default set up also need removing or the mouse will not function as it should. The ALT+F1 (for accessing GNOME menus) and ALT+F2 (for running commands) keyboard shortcuts then become crucial when your mouse is not working as it should and could avert a panic too; knowing that adjusting a single configuration file will fix a problem when doing so is less accessible is not a good feeling as I discovered to my own cost. The graphics settings were fine by default but here’s what you should have in case it isn’t for you:
Section “Device”

The next step is to ensure that your HAL settings are as they should. I needed to create a file in /usr/local/etc/hal/fdi/policy called 90-vboxguest.fdi that contains the following:

With all that set, it is time to ensure that the custom user account is added to the wheel and operator groups using this command:
pw user mod [user name] -G wheel operator
Executing the above as root means that the custom account can run the su command so that logging in as root at the start of a desktop session no longer is needed. That is what being in the wheel group allows and the anyone in the operator group can shut down or restart the system. Both are facilities readily available in Linux so I fancied having them in FreeBSD too.
Being able to switch to root in a terminal session meant that I could go on to add software like Firefox, Libreoffice, GIMP, EMACS, Geany, Netbeans, Banshee and so on. There may be a line of opinion that FreeBSD is a server operating system but all of these make it more than passable for serving as a desktop one too. There may be no package management GUI as such and the ones that come with GNOME do not work either but anyone familiar with command line working will get around that.
FreeBSD may be conservative but that has its place too and being able to build up a system one item at a time teaches far more than getting everything already sorted in one hit. So far, there is enough documentation to get me going and I hope to see where else things go too. So far, the OS hasn’t been that intimidating and that’s good to see.
With the release of Windows 8 around this time last year, I thought that the full retail version that some of us got for fresh installations on PC’s, real or virtual, had become a thing of the past. In fact, it did seem that every respecting technology news website and magazine was saying just that. The release that you would buy from Microsft or from mainstream computer stores was labelled as an upgrade. That made it look as if you needed the OEM or System Builder edition for those PC’s that needed a new Windows installation and that the licence that you bought was then attached to the machine from when it got installed on there.
As is usual with Microsoft, the situation is less clear cut than that. For instance, there was some back-pedalling to allow OEM editions of Windows to be licensed for personal use on real or virtual PC’s. With Windows & and its predecessors, it even was possible to be able to install afresh on a PC without Windows by first installing on inactivated copy on there and then upgrading that as if it was a previous version of Windows. Of course, an actual licence was of the previous version of Windows was needed for full compliance if not the actual installation. At times, Microsoft muddies waters so as to keep its support costs down.
Even with Microsoft’s track record in mind, it still did surprise me when I noticed that Amazon was selling what appeared to be full versions of both Windows 8.1 and Windows 8.1 Pro. Having set up a 64-bit VirtualBox virtual machine for Windows 8.1, I got to discovering the same for software purchased from the Microsoft web site. However, unlike the DVD versions, you do need an active Windows installation if you fancy a same day installation of the downloaded software. For those without Windows on a machine, this can be as simple as downloading either the 32-bit or the 64-bit 90 day evaluation editions of Windows 8.1 Enterprise and using that as a springboard for the next steps. This not only be an actual in-situ installation but there options to create an ISO or USB image of the installation disk for later installation.
In my case, I created a 64-bit ISO image and used that to reboot the virtual machine that had Windows 8.1 Enterprise on there before continuing with the installation. By all appearances, there seemed to be little need for a pre-existing Windows instance for it to work so it looks as if upgrades have fallen by the wayside and only full editions of Windows 8.1 are available now. The OEM version saves money so long as you are happy to stick with just one machine and most users probably will do that. As for the portability of the full retail version, that is not something that I have tested and I am unsure that I will go beyond what I have done already.
My main machine has seen a change of motherboard, CPU and memory so it could have de-activated a pre-existing Windows licence. However, I run Linux as my main operating system and, apart possibly from one surmountable hiccup, this proves surprisingly resilient in the face of such major system changes. For running Windows, I turn to virtual machines and there were no messages about licence activation during the changeover either. Microsoft is anything but confiding when it comes to declaring what hardware changes inactivate a licence. Changing a virtual machine from VirtualBox to VMware or vice versa definitely so does it so I tend to avoid doing that. One item that is fundamental to either a virtual or a real PC is the mainboard and I have seen suggestions that this is the critical component for Windows licence activation and it would make sense if that was the case.
However, this rule is not hard and fast either since there appears to be room for manoeuvre should your PC break. It might be worth calling Microsoft after a motherboard replacement to see if they can help you and I have seen that it is. All in all, Microsoft often makes what appear to be simple rules only to override them when faced with what happens in the real world. Is that why they can be unclear about some matters at times? Do they still hanker after how they want things to be even when they are impossible to keep like that?
Curiosity about the Release Preview of Windows 8 saw me running into bother when trying to see what it’s like in a VirtualBox VM. While doing some investigations on the web, I saw VMware Player being suggested as an alternative. Before discovering VirtualBox, I did have a licence for VMware Workstation and was interested in seeing what Player would have to offer. The, it was limited to running virtual machines that were created using Workstation. Now, it can create and manage them itself and without any need to pay for the tool either. Registration on VMware’s website is a must for downloading it though but that’s no monetary cost.
One I had downloaded Player from the website, I needed to install it on my machine. There are Linux and Windows versions and it was the former that I needed and there are 32-bit and 64-bit variants so you need to know what your system is running. With the file downloaded, you need to set it as executable and the following command should do the trick once you are in the right directory:
chmod +x VMware-Player-4.0.4-744019.i386.bundle
Then, it needs execution as a superuser. With sudo access for my user account, it was a matter of issuing the following command and working through the installation screens to instate the Player software on the system:
sudo ./VMware-Player-4.0.4-744019.i386.bundle
Those screens proved easy for me to follow so life would have been good if that were all that was needed to get Player working on my PC. Having Linux Mint 13 means that the kernel is of the 3,2 stock and that means using a patch to finish off the Player installation because the required VMware kernel modules seem to silently fail to compile during the installation process. This only manifests itself when you attempt to start Player afterwards to find a module installation screen appear. That wouldn’t be an issue of itself were it not for the compilation failure of the vmnet module and subsequent inability to start VMware services on the machine. There is a prompt to peer into the log file for the operation and that is a little uninformative for the non-specialist.
Rummaging around the web brought me to the requisite patch and it will work for Player 4.0.3 and Workstation 8.0.2 by default. Doing some tweaking allowed me to make it work for Player 4.04 too. My first step was to extract the contents of the tarball to /tmp where I could edit patch-modules_3.2.0.sh. Line 8 was changed to the following:
plreqver=4.0.4
With the amendment saved, it was time to execute the shell script as a superuser having made it executable before hand. This can be accomplished using the following command:
chmod +x patch-modules_3.2.0.sh && sudo ./patch-modules_3.2.0.sh
With that completed successfully, VMware Player ran as it should. An installation of Windows 8 into a new VM ran very smoothly and I was impressed with performance and responsiveness of the operating system within a Player VM. There are a few caveats though. First, it doesn’t run at all well with VMware Tools so it’s best to leave them uninstalled and it doesn’t seem to need them either; it was possible to set the resolution to the same as my screen and use the CTRL+ALT+ENTER shortcut to drop in and out of full screen mode anyway. Second, the unattended Windows installation wasn’t the way forward for setting up the VM but it was no big deal to have that experiment thwarted. The feature remains an interesting one though.
With Windows 8 running so well in Player, I was reminded of the sluggish nature of my Windows 7 VM and an issue with a Fedora 17 one too. The result was that I migrated the Windows 7 VM from VirtualBox to VMware and all is so much more responsive. Getting it there took not a little tinkering so that’s a story for another entry. On the basis of my experiences so far, I reckon that VMware Player will remain useful to me for a little while yet. Resolving the installation difficulty was worth that extra effort.
When I gave the beta version of the now finally released Fedora 15 a try, GNOME 3 left me thinking that it was even more dramatic and less desirable a change than Ubuntu’s Unity desktop interface. In fact, I was left with serious questions about its actual usability, even for someone like me. It all felt as if everything was one click further away from me and thoughts of what this could mean for anyone seriously afflicted by RSI started to surface in my mind, especially with big screens like my 24″ Iiyama being commonplace these days. Another missing item was somewhere on the desktop interface for shutting down or restarting a PC; it seemed to be a case of first logging off and then shutting down from the login screen. This was yet another case of adding to the number of steps for doing something between GNOME 2 and GNOME 3 with its GNOME Shell.
After that less than positive experience with a Live CD, you’d be forgiven for thinking that I’d be giving the GNOME edition of Fedora 15 a wide berth with the LXDE one being chosen in its place. Another alternative approach would have been to turn off GNOME Shell altogether by forcing the fallback mode to run all the time. The way to do this is start up the System Settings application and click on the System Info icon. Once in there, click on Graphics and turn on the Forced Fallback Mode option. With that done, closing down the application, logging off and then back on again will gain you an environment not dissimilar to the GNOME 2 of Fedora 14 and its forbears.
Even after considering the above easy way to get away from and maybe even avoid the world of GNOME Shell, I still decided to give it another go to see if I could make it work in a way that was less alien to me. After looking at the handy Quickstart guide, I ventured into the world of GNOME Shell extensions and very useful these have come to be too. The first of these that I added was the Alternate Status Menu and I ran the following command to do so:
yum install gnome-shell-extensions-alternative-status-menu
The result was that the “me” menu gained the ever useful “Power Off…” entry that I was seeking once I refreshed the desktop by running the command r in the command entry box produced by the ALT + F2 keyboard combination. Next up was the Place Menu and the command used to add that is:
yum install gnome-shell-extensions-place-menu
Again, refreshing the desktop as described for the Alternate Status Menu added the new menu to the (top) panel. Not having an application dock on screen all the time was the next irritation that was obliterated and it helps to get around the lack of a workspace switcher for now too. The GNOME Shell approach to virtual desktops is to have a dynamic number of workspaces with there always being one more than what you are using. It’s an interesting way of working that doesn’t perturb more pragmatic users like me, but there are those accustomed to tying applications to particular workspaces aren’t so impressed by the change. The other change to workspace handling is that keyboard shortcuts have changed to CTRL-ALT-[Up Arrow] and CTRL-ALT-[Down Arrow] from CTRL-ALT-[Left Arrow] and CTRL-ALT-[Right Arrow].
To add that application dock, I issued the command below and refreshed the desktop to get it showing. Though it stops application windows becoming fully maximised on the screen, that’s not a problem with my widescreen monitor. In fact, it even helps to switch between workspaces using the keyboard because that doesn’t seem to work when you have fully maximised windows.
yum install gnome-shell-extensions-dock
After adding the application dock, I stopped adding extensions though there are more available, such as Alternate Tab Behaviour (restores the ALT-TAB behaviour of GNOME 2), Auto-Move Windows, Drive Menu, Native Window Placement, Theme Selector and Window Navigator. Here are the YUM commands for each of these in turn:
yum install gnome-shell-extensions-alternate-tab
yum install gnome-shell-extensions-auto-move-windows
yum install gnome-shell-extensions-drive-menu
yum install gnome-shell-extensions-native-window-placement
yum install gnome-shell-extensions-theme-selector
yum install gnome-shell-extensions-user-theme
yum install gnome-shell-extensions-windowsNavigator
One hope that I will retain is that more of these extensions will appear over time, but Ranjith Siji seems to have a good round up of what is available. Other than these, I also have added the DCONF Editor and GNOME Tweaks Tool with the latter restoring buttons for minimising and maximising windows to their title bars for me. As ever, YUM was called to add them using the following commands:
yum install dconf-editor
yum install gnome-tweaks-tool
There are other things that can be done with these but I haven’t explored them yet. All YUM commands were run as root and the ones that I used certainly have helped me to make myself at home in what once was a very unfamiliar desktop environment for me. In fact, I am beginning to like what has been done with GNOME 3 though I have doubts as to how attractive it would be to a user coming to Linux from the world of Windows. While everything is solidly crafted, the fact that I needed to make some customisations of my own raises questions about how suitable the default GNOME set-up in Fedora is for a new user though Fedora probably isn’t intended for that user group anyway. Things get more interesting when you consider distros favouring new and less technical users, both of whom need to be served anyway.
Ubuntu has gone its own way with Unity and, having spent time with GNOME 3, I can see why they might have done that. Unity does put a lot more near at hand on the desktop than is the case with GNOME 3 where you find yourself going to the Activities window a lot, either by using your mouse or by keystrokes like the “super” (or Windows) key or ALT-F1. Even so, there are common touches like searching for an application like you would search for a web page in Firefox. In retrospect, it is a pity to see the divergence when something from both camps might have helped for a better user experience. Nevertheless, I am reaching the conclusion that the Unity approach feels like a compromise and that GNOME feels that little bit more polished. Saying that, an extra extension or two to put more items nearer to hand in GNOME Shell would be desirable. If I hadn’t found a haven like Linux Mint where big interface changes are avoided, maybe going with the new GNOME desktop mightn’t have been a bad thing to do after all.
Part of some recent “fooling” brought on by the investigation of what turned out to be a duff DVD writer was a fresh installation of Ubuntu 8.10 on my main home PC. It might have brought on a certain amount of upheaval but it was nowhere near as severe as that following the same sort of thing with a Windows system. A few hours was all that was needed but the question as to whether it is better to do an upgrade every time a new Ubuntu release is unleashed on the world or to go for a complete virgin installation instead. With Ubuntu 9.04 in the offing, that question takes on a more immediate significance than it otherwise might do.
Various tricks make the whole reinstallation idea more palatable. For instance, many years of Windows usage have taught me the benefits of separating system and user files. The result is that my home directory lives on a different disk to my operating system files. Add to that the experience of being able to reuse that home drive across different Linux distros and even swapping from one distro to another becomes feasible. From various changes to my secondary machine, I can vouch that this works for Ubuntu, Fedora and Debian; the latter is what currently powers the said PC. You might have to user superuser powers to attend to ownership and access issues but the portability is certainly there and it applies anything kept on other disks too.
Naturally, there’s always the possibility of losing programs that you have had installed but losing the clutter can be liberating too. However, assembling a script made up up of one of more apt-get install commands can allow you to get many things back at a stroke. For example, I have a test web server (Apache/MySQL/PHP/Perl) set up so this would be how I’d get everything back in place before beginning further configuration. It might be no bad idea to back up your collection of software sources either; I have yet to add all of the ones that I have been using back into Synaptic. Then there are closed source packages such as VirtualBox (yes, I know that there is an open source edition) and Adobe Reader. After reinstating the former, all my virtual machines were available for me to use again without further ado. Restoring the latter allowed me to grab version 9.1 (probably more secure anyway) and it inveigles itself into Firefox now too so the number of times that I need to go through the download shuffle before seeing the contents of a PDF are much reduced, though not completely eliminated by the Windows-like ability to see a PDF loaded in a browser tab. Moving from software to hardware for a moment, it looks like any bespoke actions such as my activating an Epson Perfection 4490 Photo scanner need to be repeated but that was all that I needed to do. Getting things back into order is not so bad but you need to allow a modicum of time for this.
What I have discussed so far are what might be categorised as the common or garden aspects of a clean installation but I have seen some behaviours that make me wonder if the usual Ubuntu upgrade path is sufficiently complete in its refresh of your system. The counterpoint to all of this is that I may not have been looking for some of these things before now. That may apply to my noticing that DSLR support seems to be better with my Canon and Pentax cameras both being picked up and mounted for me as soon as they are connected to a PC, the caveat being that they are themselves powered on for this to happen. Another surprise that may be new is that the BBC iPlayer’s Listen Again works without further work from the user, a very useful development. It very clearly wasn’t that way before I carried out the invasive means. My previous tweaking might have prevented the in situ upgrade from doing its thing but I do see the point of not upsetting people’s systems with an overly aggressive update process, even if it means that some advances do not make themselves known.
So what’s my answer regarding which way to go once Ubuntu Jaunty Jackalope appears? For sake of avoiding initial disruption, I’d be inclined to go down the Update Manager route first while reserving the right to do a fresh installation later on. All in all, I am left with the gut feeling is that the jury is still out on this one.
On the surface of it, this probably sounds a very strange thing to do: choose Linux Mint because they plan to stick with their current desktop interface for the foreseeable future and then stick a brand new one on there. However, that’s what last weekend’s dalliance with Fedora 15 caused. Not only did I find that I could find my way around GNOME Shell but I actually got to like it so much that I missed it on returning to using my Linux Mint machine again.
The result was that I started to look on the web to see if there was anyone else like me who had got the same brainwave. In fact, it was Mint’s being based on Ubuntu that allowed me to get GNOME 3 on there. The task could be summarised as involving three main stages: getting GNOME 3 installed, adding extensions and adding the Cantarell font that is used by default. After these steps, I gained a well-running GNOME 3 desktop running on Linux Mint and it looks set to stay that way unless something untoward has yet to emerge.
Installing GNOME 3
The first step is to add the PPA repository for GNOME 3 using the following command:
sudo add-apt-repository ppa:gnome3-team/gnome3
The, it was a case of issuing my usual update/upgrade command:
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
When that had done its thing and downloaded and installed quite a few upgrades along the way, it was time to add GNOME Shell using this command:
sudo apt-get install gnome-shell
When that was done, I rebooted my system to be greeted by a login screen very reminiscent of what I had seen in Fedora. While compiling this piece, I noticed that GNOME Session could need to be added before GNOME Shell but I do not recall doing so myself. Maybe dependency resolution kept any problems at bay, but there weren’t any issues that I could remember beyond things not being configured as fully as I would have liked without further work. For the sake of safety, it might be a good idea to run the following before adding GNOME Shell to your PC.
sudo apt-get install gnome-session && sudo apt-get dist-upgrade
Configuration and Customisation
Once I had logged in, the desktop that I saw wasn’t at all unlike the Fedora one and everything seemed stable too. However, there was still work to do before I was truly at home with it. One thing that was needed was the ever useful GNOME Tweak Tool. This came in very handy for changing the theme that was on display to the standard Adwaita one that caught my eye while I was using Fedora 15. Adding buttons to application title bars for minimising and maximising their windows was another job that the tool allowed me to do. The command to get this goodness added in the first place is this:
sudo apt-get install gnome-tweak-tool
The next thing that I wanted to do was add some extensions so I added a repository from which to do this using the command below. Downloading them via Git and compiling them just wasn’t working for me so I needed another approach.
sudo add-apt-repository ppa:ricotz/testing
With that is place, I issued the following commands to gain the Dock, the Alternative Status Menu and the Windows Navigator. The second of these would have added a shutdown option in the me-menu but it seems to have got deactivated after a system update. Holding down the ALT key to change the Suspend entry to Power off… will have to do me for now. Having the dock is the most important and that, thankfully, is staying the course and works exactly as it does for Fedora.
sudo apt-get install gnome-shell-extensions-dock
sudo apt-get install gnome-shell-extensions-alternative-status-menu
sudo apt-get install gnome-shell-extensions-windows-navigator
Adding Cantarell
The default font used by GNOME 3 in various parts of its interface is Cantarell and it was defaulting to that standard sans-serif font on my system because this wasn’t in place. That font didn’t look too well so I set to tracking the freely available Cantarell down on the web. When that search brought me to Font Squirrel, I downloaded the zip file containing the required TTF files. The next step was to install them and, towards that end, I added Fontmatrix using this command:
sudo apt-get install fontmatrix
That gave me a tool with a nice user interface but I made a mistake when using it. This was because I (wrongly) thought that it would copy files from the folder that I told the import function to use. Extracting the TTF files to /tmp meant that would have had to happen, but Fontmatrix just registered them instead. A reboot confirmed that they hadn’t been copied or moved at all and I had rendered the user interface next to unusable through my own folly; the default action on Ubuntu and Linux Mint is that files are deleted from /tmp on shutdown. The font selection capabilities of the GNOME Tweak Tool came in very handy for helping me to convert useless boxes into letters that I could read.
Another step was to change the font line near the top of the GNOME Shell stylesheet (never thought that CSS usage would end up in places like this…) so that Cantarell wasn’t being sought and text in sans-serif font replaced grey and white boxes. The stylesheet needs to be edited as superuser, so the following command is what’s needed for this and, while I used sudo, gksu
is just as useful here if it isn’t what I should have been using.
sudo gedit /usr/share/gnome-shell/theme/gnome-shell.css
Once I had extricated my system from that mess, a more conventional approach was taken and the command sequence below was what I followed, with extensive use of sudo to get done what I wanted. A new directory was created and the TTF files copied in there.
cd /usr/share/fonts/truetype
sudo mkdir ttf-cantarell
cd ttf-cantarell
sudo mv /tmp/*.ttf .
To refresh the font cache, I resorted to the command described in a tutorial in the Ubuntu Wiki:
sudo fc-cache -f -v
Once that was done, it was then time to restore the reference to Cantarell in the GNOME Shell stylesheet and reinstate its usage in application windows using the GNOME Tweak Tool. Since then, I have suffered no mishap or system issue with GNOME 3. Everything seems to be working quietly and I am happy to see that replacement of Unity with the GNOME Shell will become an easier task in Ubuntu 11.10, the first alpha release of which is out at the time of my writing these words. Could it lure me back from my modified instance of Linux Mint yet? While I cannot say that I am sure of those but it certainly cannot be ruled out at this stage.
Though my main home PC runs Linux Mint, I do like to have the facility to use Windows software from time to time and virtualisation has allowed me to continue doing that. For a good while, it was a Windows 7 guest within a VirtualBox virtual machine and, before that, one running Windows XP fulfilled the same role. However, it did feel as if things were running slower in VirtualBox than once might have been the case and I jumped ship to VMware Player. It may be proprietary and closed source but it is free of charge and has been doing what was needed. A subsequent recent upgrade of video driver on the host operating system allowed the enabling of a better graphical environment in the Windows 7 guest.
Instability
However, there were issues with stability and I lost the ability to flit from the VM window to the Linux desktop at will with the system freezing on me and needing a reboot. Working in Windows 7 using full screen mode avoided this but it did feel as I was constrained to working in a Windows machine whenever I did so. The graphics performance was imperfect too with screening refreshing being very blocky with some momentary scrambling whenever I opened the Start menu. Others would not have been as patient with that as I was though there was the matter of an expensive Photoshop licence to be guarded too.
In hindsight, a bit of pruning could have helped. An example would have been driver housekeeping in the form of removing VirtualBox Guest Additions because they could have been conflicting with their VMware counterparts. For some reason, those thoughts entered my mind and I was pondering another more expensive option instead.
Considering NAS & Windows/Linux Networking
That would have taken the form of setting aside a PC for running Windows 7 and having a NAS for sharing files between it and my Linux system. In fact, I did get to exploring what a four bay QNAP TS-412 would offer me and realised that you cannot put normal desktop hard drives into devices like that. For a while, it looked as if it would be a matter of getting drives bundled with the device or acquiring enterprise grade disks so as to main the required continuity of operation. The final edition of PC Plus highlighted another one though: the Western Digital Red range. These are part way been desktop and enterprise classifications and have been developed in association with NAS makers too.
Looking at the NAS option certainly became an education but it has exited any sort of wish list that I have. After all, there is the cost of such a setup and it’s enough to get me asking if I really need such a thing. The purchase of a Netgear FS 605 ethernet switch would have helped incorporate it but there has been no trouble sorting alternative uses for it since it bumps up the number of networked devices that I can have, never a bad capability to have. As I was to find, there was a less expensive alternative that became sufficient for my needs.
In-situ Windows 8 Upgrade
Microsoft have been making available evaluation copies of Windows 8 Enterprise that last for 90 days before expiring. One is in my hands has been running faultlessly in a VMware virtual machine for the past few weeks. That made me wonder if upgrading from Windows 7 to Windows 8 help with my main Windows VM problems. Being a curious risk-taking type I decided to answer the question for myself using the £24.99 Windows Pro upgrade offer that Microsoft have been running for those not needing a disk up front; they need to pay £49.99 but you can get one afterwards for an extra £12.99 and £3.49 postage if you wish, a slightly cheaper option. There also was a time cost in that it occupied a lot of a weekend on me but it seems to have done what was needed so it was worth the outlay.
Given the element of risk, Photoshop was deactivated to be on the safe side. That wasn’t the only pre-upgrade action that was needed because the Windows 8 Pro 32-bit upgrade needs at least 16 GB before it will proceed. Of course, there was the matter of downloading the installer from the Microsoft website too. This took care of system evaluation and paying for the software as well as the actual upgrade itself.
The installation took a few hours with virtual machine reboots along the way. Naturally, the licence key was needed too as well as the selection of a few options though there weren’t many of these. Being able to carry over settings from the pre-exisiting Windows 7 instance certainly helped with this and with making the process smoother too. No software needed reinstatement and it doesn’t feel as if the system has forgotten very much at all, a successful outcome.
Post-upgrade Actions
Just because I had a working Windows 8 instance didn’t mean that there wasn’t more to be done. In fact, it was the post-upgrade sorting that took up more time than the actual installation. For one thing, my digital mapping software wouldn’t work without .Net Framework 3.5 and turning on the operating system feature form the Control Panel fell over at the point where it was being downloaded from the Microsoft Update website. Even removing Avira Internet Security after updating it to the latest version had no effect and it was a finding during the Windows 8 system evaluation process. The solution was to mount the Windows 8 Enterprise ISO installation image that I had and issue the following command from a command prompt running with administrative privileges (it’s all one line though that’s wrapped here):
dism.exe /online /enable-feature /featurename:NetFX3 /Source:d:\sources\sxs /LimitAccess
For sake of assurance regarding compatibility, Avira has been replaced with Trend Micro Titanium Internet Security. The Avira licence won’t go to waste since I have another another home in mind for it. Removing Avira without crashing Windows 8 proved impossible though and necessitating booting Windows 8 into Safe Mode. Because of much faster startup times, that cannot be achieved with a key press at the appropriate moment because the time window is too short now. One solution is to set the Safe Boot tickbox in the Boot tab of Msconfig (or System Configuration as it otherwise calls itself) before the machine is restarted. There may be others but this was the one that I used. With Avira removed, clearing the same setting and rebooting restored normal service.
Dealing with a Dual Personality
One observer has stated that Windows 8 gives you two operating systems for the price of one: the one in the Start screen and the one on the desktop. Having got to wanting to work with one at a time, I decided to make some adjustments. Adding Classic Shell got me back a Start menu and I left out the Windows Explorer (or File Explorer as it is known in Windows 8) and Internet Explorer components. Though Classic Shell will present a desktop like what we have been getting from Windows 7 by sweeping the Start screen out of the way for you, I found that this wasn’t quick enough for my liking so I added Skip Metro Suite to do this and it seemed to do that a little faster. The tool does more than sweeping the Start screen out of the way but I have switched off these functions. Classic Shell also has been configured so the Start screen can be accessed with a press of Windows key but you can have it as you wish. It has updated too so that boot into the desktop should be faster now. As for me, I’ll leave things as they are for now. Even the possibility of using Windows’ own functionality to go directly to the traditional desktop will be left untested while things are left to settle. Tinkering can need a break.
Outcome
After all that effort, I now have a seemingly more stable Windows virtual machine running Windows 8. Flitting between it and other Linux desktop applications has not caused a system freeze so far and that was the result that I wanted. There now is no need to consider having separate Windows and Linux PC’s with a NAS for sharing files between them so that option is well off my wish-list. There are better uses for my money.
Not everyone has had my experience though because I saw a report that one user failed to update a physical machine to Windows 8 and installed Ubuntu instead; they were a Linux user anyway even if they used Fedora more than Ubuntu. It is possible to roll back from Windows 8 to the previous version of Windows because there is a windows.old directory left primarily for that purpose. However, that may not help you if you have a partially operating system that doesn’t allow you to do just that. In time, I’ll remove it using the Disk Clean-up utility by asking it to remove previous Windows installations or running File Explorer with administrator privileges. Somehow, the former approach sounds the safer.
What About Installing Afresh?
While there was a time when I went solely for upgrades when moving from one version of Windows to the next, the annoyance of the process got to me. If I had known that installing the upgrade twice onto a computer with a clean disk would suffice, it would have saved me a lot. Staring from Windows 95 (from the days when you got a full installation disk with a PC and not the rescue media that we get now) and moving through a sequence of successors not only was time consuming but it also revealed the limitations of the first in the series when it came to supporting more recent hardware. It was enough to have me buying the full retailed editions of Windows XP and Windows 7 when they were released; the latter got downloaded directly from Microsoft. These were retail versions that you could move from one computer to another but Windows 8 will not be like that. In fact, you will need to get its System Builder edition from a reseller and that can only be used on one machine. It is the merging of the former retail and OEM product offerings.
What I have been reading is that the market for full retail versions of Windows was not a big one anyway. However, it was how I used to work as you have read above and it does give you a fresh system. Most probably get Windows with a new PC and don’t go building them from scratch like I have done for more than a decade. Maybe the System Builder version would apply to me anyway and it appears to be intended for virtual machine use as well as on physical ones. More care will be needed with those licences by the looks of things and I wonder what needs not to be changed so as not to invalidate a licence. After all, making a mistake might cost between £75 and £120 depending on the edition.
Final Thoughts
So far Windows 8 is treating me well and I have managed to bend to my will too, always a good thing to be able to say. In time, it might be that a System Builder copy could need buying yet but I’ll leave well alone for now. Though I needed new security software, the upgrade still saved me money over a hardware solution to my home computing needs and I have a backup disk on order from Microsoft too. That I have had to spend some time settling things was a means of learning new things for me but others may not be so patient and, with Windows 7 working well enough for most, you have to ask if it’s only curious folk like me who are taking the plunge. Still, the dramatic change has re-energised the PC world in an era when smartphones and tablets have made so much of the running recently. That too is no bad thing because an unchanging technology is one that dies and there are times when big changes are needed, as much as they upset some folk. For Microsoft, this looks like one of them and it’ll be interesting to see where things go from here for PC technology.
Here are some useful locations in the Arch Linux wiki for those wishing to set up an Arch Linux installation for the first time without recourse to the likes of Architect Linux or Anarchy Installer. It is an endeavour that takes more time than other distros since Arch prefers to tell you how to do things instead of going and doing them for you. Some may admire the learning opportunities while more prefer if they were not forced to do so much. Since Arch is meant for more technical folk with the patience for getting around technical glitches, then their well documented ways are an impressive sight. The list is a living one and sticks to getting a web server set up for now but I do plan to add to it on an ongoing basis.
Essentials
In spite of its name suggesting a starting point for any user, this is for more experienced users of Linux. As with the beginner’s guide, you have to look elsewhere when it comes to installing a desktop environment such as GNOME Shell, Cinnamon or KDE, to name only three.
When I ran into issues with setting up network interfaces during one installation of Arch (that was when setting up a virtual web server), this is where I went looking and I did sort out what was causing the bother too.
Desktop Environment
In spite of it being stated in the Beginner’s Guide that VirtualBox Guest Additions are installed by default, that was not my experience during my setting up of an Arch instance that only has the Cinnamon desktop environment. The X server wouldn’t work until the requisite package was instated.
Once you get a functioning X server installed, the next step is to get a display manager added. There is GDM but I wanted to avoid too many GNOME components because it was Cinnamon 2.0 that was to be my choice of desktop environment. LightDM looked a neutral choice so I went with that.
While I have set up Arch with GNOME as its desktop environment before, my hearing that Cinnamon 2.0 no longer is tied to GNOME was enough to get me setting up an instance of Arch with only Cinnamon as the desktop environment. It was a dalliance with Antergos, an Arch-based distro, that revealed that Cinnamon 2.0 was available for its users and I never would have gone near Arch to sate my curiosity were it not for the inability of the installer to run with download failures. With Arch, there was more to do but, once the X Server was able to run and a display manager was in place, the installation was not too hard to do either.
Servers
Setting up a Web Server (XAMPP)
There are some differences between Arch Linux and the likes of Ubuntu Server, so this description is worth consulting. The use of Systemd is one of those since Arch is more cutting edge in technology terms and it also has replaced MySQL with MariaDB, a folk of the same, too. Once you learn to deal with those, you are on your way.
Another difference you find with Arch is that ProFTPD is not in its non-AUR repositories so you need to look at vsftpd (or Very Secure FTP Daemon) instead and here is a page saying more about that FTP server option.
