Sorting a kernel upgrade error in Linux Mint 13
30th November 2012Linux Mint 14 may be out now, but I'll be sticking with its predecessor for now. Being a user of GNOME Shell instead of Cinnamon or Mate, I'll wait for extensions to get updated for 3.6 before making a move away from 3.4 where the ones that I use happily work. Given that Linux Mint 13 is set to get support until 2017, it's not as if there is any rush either. Adding the back-ported packages repository to my list of software sources means that I will not miss out on the latest versions of MDM, Cinnamon and Mate anyway. With Ubuntu set to stick to GNOME 3.6 until after 13.04 is released, adding the GNOME 3 Team PPA will be needed if 3.8 arrives with interesting goodies; there are interesting noises that suggest the approach taken in Linux Mint 12 may be used to give more of a GNOME 2 desktop experience. Options abound and there are developments in the pipeline that I hope to explore too.
However, there is one issue that I have had to fix which stymies upgrades within the 3.2 kernel branch. A configuration file (/etc/grub.d/10_linux) points to /usr/share/grub/grub-mkconfig_lib instead of /usr/lib/grub/grub-mkconfig_lib so I have been amending it every time I needed to do a kernel update. However, it just reverts to the previous state, so I thought of another solution: creating a symbolic link in the incorrect location that points to the correct one so that updates complete without manual intervention every time. The command that does the needful is below:
sudo ln -s /usr/lib/grub/grub-mkconfig_lib /usr/share/grub/grub-mkconfig_lib
Of course, figuring out what causes the reversion would be good too, but the symbolic link fix works so well that there's little point in exploring it further. Of course, if anyone can add how you'd do that, I'd welcome this advice too. New knowledge is always good.
Presenting more than one plot on a page using SAS ODS PDF
12th November 2012If you had asked me about getting two or more graphs on a page using SAS/GRAPH procedures, I might have suggested PROC GREPLAY as the means to achieve it. However, I recently came across another way to do the same thing by using ODS. It helped that the graphs were being produced using the PDF destination because I doubt that what follows will work with the RTF one.
For this three plots on a page example, I first set the orientation to landscape so that the plots can be arranged side by side in a single row:
options orientation=landscape;
Next, the PDF destination was opened with page breaks turned off for the required output file using the STARTPAGE option:
ods pdf file="c:\test.pdf" startpage=off;
The listing destination was turned off as well since it is not needed:
ods listing close;
With that complete, a page or region break gets inserted. While this could have been repeated before every procedure to get it popped into the next region on the page, that is the default behaviour for any extra procedural step, so it wasn't needed.
ods pdf startpage=now;
Then, the ODS LAYOUT feature is started so that the layout can be defined on the page:
ods layout start;
For the first plot and the one at the left of the triptych, a region was defined absolutely (grid layouts are available, but I didn't make use of them here) using ODS REGION. Since all plots were to be of the same size, the width was defined as being a third of the page and the bottom left-hand corner of the region defined to be the same as that of the plot area on the page. Titles and footnotes usefully lie outside this region in the way that SAS arranges things, so there is no further messing. With the region defined, it's a matter of running the required SAS/GRAPH procedure. In my case, this was GPLOT, but I am certain that others would work as well. The height was defined as the full possible plot height. This could have a use if I wanted more than one row of graphs on a page, with a trellis plot being an example of that sort of arrangement.
ods region x=0pct y=0pct width=33pct height=100pct;
<< SAS/GRAPH Procedure >>
For the middle plot, the starting position is moved a third of the way along the page, while the section area has the same dimensions as before. Using percentages in these definitions does make their usage easier.
ods region x=33pct y=0pct width=33pct height=100pct;
<< SAS/GRAPH Procedure >>
Lastly, the right-hand plot has a starting position two-thirds of the width of the page and the other dimensions are as per the other panels:
ods region x=66pct y=0pct width=33pct height=100pct;
<< SAS/GRAPH Procedure >>
With the last graph created, it is time to close ODS LAYOUT and the PDF destination. Then, the listing destination is reopened again.
ods layout end;
ods pdf close;
ods listing;
Update 2012-12-08: Since writing the above, I have learned that ODS LAYOUT and ODS REGION have yet to become production features of SAS with 9.3 as the latest version. However, I have encountered an alternative that uses the STARTPAGE=NEVER ODS PDF option to turn off page breaks and GOPTIONS statements to control the regions occupied by plots. It's Sample 48569 on the SAS website. Having a production equivalent is better, since pre-production features are best avoided in production code. If I had realised the status, I would have used PROC GREPLAY to achieve what I needed to do.
Upgrading from Windows 7 to Windows 8 in a VMWare Virtual Machine
1st November 2012Though my main home PC runs Linux Mint, I do like to have the facility to use Windows software occasionally, 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, so I jumped ship to VMware Player. While it may be proprietary and closed source, it is free of charge and has been doing what was needed. A subsequent recent upgrade of a 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, yet it did feel as I was constrained to working on a Windows-only 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 to make me consider 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 to main the required continuity of operation. The final edition of PC Plus highlighted another one, though: the Western Digital Red Pro range. These are part way been desktop and enterprise classifications and have been developed in association with NAS makers too.
While looking at the NAS option certainly became an education, it has exited any sort of wish list that I have. After all, it is the cost of such a setup that gets me asking if I really need such a thing. While the purchase of a Netgear FS 605 Ethernet switch would have helped incorporate it, there has been no trouble sorting alternative uses for that device 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 would become sufficient for my needs.
In-situ Windows 8 Upgrade
Microsoft has 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 while you can get one afterwards for an extra £12.99 and £3.49 postage if you wish, a slightly cheaper option. Though there also was a time cost in that it occupied a lot of a weekend for me, 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-existing 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 from 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 that 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:
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 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 tick box in the Boot tab of MSCONFIG (or System Configuration, as it otherwise calls itself) before the machine is restarted. While there may be others, 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 on 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 omitted 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 speed up things. Though the tool does more than sweeping the Start screen out of the way, I have switched off these functions. Classic Shell also has been configured, so the Start screen can be accessed with a press of the Windows key. 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. While these were retail versions that you could move from one computer to another, 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 significant 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.
Adding a Start Menu to Windows 8
16th October 2012For all the world, it looks like Microsoft has mined a concept from a not often recalled series of Windows: 3.x. Then, we had a Program Manager for starting all our applications, with no sign of a Start Menu. That came with Windows 95 and I cannot see anyone mourning the burying of the Program Manager interface either. It was there in Windows 95 if you knew where to look, and I do remember starting an instance, possibly out of curiosity.
Every Windows user seems to have taken to the Start Menu, regardless of how big it can grow when you install a lot of software on your machine. It didn't matter that Windows NT got it later than Windows 9x ones either; NT 3.51 has the Program Manager too, and it was NT 4 that got the then new interface that has been developed and progressed in no less than four subsequent versions of Windows (2000, XP, Vista & 7). Maybe it was because computing was the preserve of fewer folk that the interchange brought little if any sign of a backlash. The zeitgeist of the age reflected the newness of desktop computing, and its freshness probably brought an extra level of openness too.
Things are different now, though. You only have to hear of the complaints about changes to Linux desktop environments to realise how attached folk become to certain computer interfaces. Ironically, personal computing has just got exciting again after a fairly stale decade of stasis. Mobile computing devices are aplenty nowadays, and it no longer is a matter of using a stationary desktop PC or laptop, even if those brought their own excitement in the 1990's. In fact, reading a title like Computer Shopper reminds me of how things once were with it's still sticking with PC reviews while others are not concentrating on them as much. Of course, the other gadgets get reviewed too, so it is not stuck in any rut. Still, it is good to see the desktop PC getting a look in an age when there is so much competition, especially from phones and tablets.
In this maelstrom, Microsoft has decided to do something dramatic with Windows 8. It has resurrected the Program Manager paradigm in the form of the Start screen and excised the Start Menu from the desktop altogether. For touch screen computing interfaces such as tablets, you can see the sense of this, but it's going to come as a major surprise to many. Removing what lies behind how many people interact with a PC is risky, so you have to wonder how it will work out for all concerned.
What reminded me of this was a piece on CNET by Mary Jo Foley. Interestingly, software is turning up that returns the Start Menu to Windows 8. One of these is Classic Shell, and I decided to give it a go on a Windows 8 Enterprise evaluation instance that I have. Installation is like any Windows program, and I limited the options to the menu and updater. At the end of the operation, a button with a shell icon appeared on the desktop's taskbar. You can make the resultant menu appear like that of Windows XP or Windows 7 if you like. There are other settings like what the Windows key does and what happens when you click on the button with a mouse. By default, both open the new Start Menu, and holding down the Shift key when doing either brings up the Start screen. This is customisable, so you can have things the other way around if you so desire. Another setting is to switch from the Start screen to the desktop after you log into Windows 8 (you may also have it log in for you automatically, but it's something that I do not think anyone should be doing). While the Start screen does flash up, things move along quickly; maybe having not appear at all would be better for many.
Classic Shell is free of charge and worked well for me, apart from that small rough edge noted above. It is also open source and looks well maintained too. For that reason, it appeals to me more than Stardock's Start8 (currently in beta release at the time of writing) or Pokki for Windows 8, which really is an App Store that adds a Start Menu. If you encounter Windows 8 on a new computer, then they might be worth trying should you want a Start Menu back. Being an open-minded type, I could get along with the standard Windows 8 interface, yet it's always good to have choices too. Most of us want to own our computing experience, it seems, so these tools could have their uses for Windows 8 users.
Moving a Windows 7 VM from VirtualBox to VMware Player
14th October 2012Seeing how well Windows 8 was running in a VMware Player virtual machine and that was without installing VMware Tools in the guest operating system, I was reminded about how sluggish my Windows 7 VirtualBox VM had become. Therefore, I decided to try a migration of the VM from VirtualBox to VMware. My hope was this: it would be as easy as exporting to an OVA file (File > Export Appliance... in VirtualBox) and importing that into VMware (File > Open a VM in Player). However, even selecting OVF compatibility was insufficient for achieving this, and the size of the virtual disks meant that the export took a while to run as well. The solution was to create a new VM in VirtualBox from the OVA file and use the newly created VMDK files with VMware. That worked successfully to give me a speedier, more responsive Windows 7 VM for my pains.
Access to host directories needed reinstatement using a combination of the VMware Shared Folders feature and updating drive mappings in Windows 7 itself to use what appeared to it as network drives in the Shared Folders directory on the \\vmware-host domain. For that to work, VMware Tools needed to be installed in the guest OS (go to Virtual Machine > Install VMware Tools to make available a virtual CD from which the installation can be done) as I discovered when trying the same thing with my Windows 8 VM, where I dare not instate VMware Tools due to their causing trouble when I last attempted it.
Moving virtual machine software brought about its side effects, though. Software like Windows 7 detects that it's on different hardware, so reactivation can be needed. While Windows 7 reactivation was a painless online affair, it wasn't the same for Photoshop CS5. That meant that I needed help from Adobe's technical support people top get past the number of PC's for which the software already had been activated. In hindsight, deactivation should have been done before the move, but that's a lesson that I know well now. Technical support sorted my predicament politely and efficiently while reinforcing the aforementioned learning point. Moving virtual machine platform is very like moving from one PC to the next, and it hadn't clicked with me quite how real those virtual machines can be when it comes to software licensing.
Apart from that and figuring out how to do it, the move went smoothly. An upgrade to the graphics driver on the host system and getting Windows 7 to recheck the capabilities of the virtual machine even gained me a fuller Aero experience than I had before then. Full screen operation is quite reasonable too (the CTRL + ALT + ENTER activates and deactivates it) and photo editing now feels less boxed in too.
A belated goodbye to PC Plus magazine
13th October 2012Last year, Future Publishing made a loss, so something had to be done to address that. Computer magazines such as Linux Format no longer could enclose their cover-mounted discs in elaborate cardboard wallets and moved to simpler sleeves instead. Another casualty has been one of their longest standing titles: PC Plus.
It has been around since 1986 and possibly was one of the publisher's first titles. It was the late nineties when I first encountered and, for quite a few years afterwards, it was my primary computer magazine of choice every month. The mix of feature articles, reviews and tutorials covering a variety of aspects of personal computing was enough for me. After a while, though, it became a bit stale and I stopped buying it regularly. Then, the collection that I had built up was dispatched to the recycling bin and I turned to other magazines.
In the late nineties, Future had a good number of computing titles on magazine shelves in newsagents, and there did seem to be some overlap in content. For instance, we had PC Answers and PC Format alongside PC Plus at one point. Now, only PC Format is staying with us and its market seems to be high home computer users such as those interested in PC gaming. .Net, initially a web usage title and now one focussing on website design and development, started from the same era and Linux Format dates from around the turn of the century. Looking back, it looks like there was a lot of duplication going on in a heady time of expanding computer usage.
That expansion may have killed off PC Plus in the end. For me, it certainly meant that it no longer was a one-stop shop like Dennis's PC Pro. For instance, the programming and web design content that used to come in PC Plus found itself appearing in .Net and in Linux Format. The appearance of the latter certainly meant that was somewhere else for Linux content; for the record, my first dalliance with SuSE Linux was from a PC Plus cover-mounted disk. The specialisation and division certainly made PC Plus a less essential read than I once thought it.
The current economic downturn coincides with significant shifts in publishing. Digital publishing is expanding beyond just websites, which likely contributes to Future's recent financial results. The perceived lack of importance of a title like PC Plus can lead to its discontinuation, though I believe past overexpansion was the primary cause. Perhaps a single Future computing magazine with in-depth reviews, tutorials on programming and open-source software, and consolidated content from other magazines could have changed things. However, even that might not have been commercially viable. Consequently, the present situation is different, and PC Plus is no longer a magazine I read monthly. Its disappearance from newsstands, even though it fell off my reading list some time ago, is regrettable.
Using the IN operator in SAS Macro programming
8th October 2012This useful addition came in SAS 9.2, and I am amazed that it isn’t enabled by default. To accomplish that, you need to set the MINOPERATOR option, unless someone has done it for you in the SAS AUTOEXEC or another configuration program. Thus, the safety first approach is to have code like the following:
options minoperator;
%macro inop(x);
%if &x in (a b c) %then %do;
%put Value is included;
%end;
%else %do;
%put Value not included;
%end;
%mend inop;%inop(a);
Also, the default delimiter is the space, so if you need to change that, then the MINDELIMITER option needs setting. Adjusting the above code so that the delimiter now is the comma character gives us the following:
options minoperator mindelimiter=",";
%macro inop(x);
%if &x in (a b c) %then %do;
%put Value is included;
%end;
%else %do;
%put Value not included;
%end;
%mend inop;%inop(a);
Without any of the above, the only approach is to have the following, and that is what we had to do for SAS versions before 9.2:
%macro inop(x);
%if &x=a or &x=b or &x=c %then %do;
%put Value is included;
%end;
%else %do;
%put Value not included;
%end;
%mend inop;%inop(a);
While it may be clunky, it does work and remains a fallback in newer versions of SAS. Saying that, having the IN operator available makes writing SAS Macro code that little bit more swish, so it's a good thing to know.
Setting up MySQL on Sabayon Linux
27th September 2012For quite a while now, I have offline web servers for doing a spot of tweaking and tinkering away from the gaze of web users that visit what I have on there. Therefore, one of the tests that I apply to any prospective main Linux distro is the ability to set up a web server on there. This is more straightforward for some than for others. For Ubuntu and Linux Mint, it is a matter of installing the required software and doing a small bit of configuration. My experience with Sabayon is that it needs a little more effort than this, so I am sharing it here for the installation of MySQL.
The first step is to install the software using the commands that you find below. The first pops the software onto the system while the second completes the set-up. The --basedir option is need with the latter because it won't find things without it. It specifies the base location on the system, and it's /usr in my case.
sudo equo install dev-db/mysql
sudo /usr/bin/mysql_install_db --basedir=/usr
With the above complete, it's time to start the database server and set the password for the root user. That's what the two following commands achieve. Once your root password is set, you can go about creating databases and adding other users using the MySQL command line
sudo /etc/init.d/mysql start
mysqladmin -u root password 'password'
The last step is to set the database server to start every time you start your Sabayon system. The first command adds an entry for MySQL to the default run level so that this happens. The purpose of the second command is to check that this happened before restarting your computer to discover if it really happens. This procedure also is necessary for having an Apache web server behave in the same way, so the commands are worth having and even may have a use for other services on your system. ProFTP is another that comes to mind, for instance.
sudo rc-update add mysql default
sudo rc-update show | grep mysql
Getting rid of a Dropbox error message on a Linux-powered PC
24th September 2012One of my PC's has ended up becoming a testing ground for a number of Linux distributions. The list has included openSUSE, Fedora, Arch and LMDE with Sabayon being the latest incumbent. From Arch onwards in that list, though, a message has appeared on loading the desktop with every one of these when I have Dropbox's client set up on there:
Unable to monitor entire Dropbox folder hierarchy. Please run "echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches" and restart Dropbox to correct the problem.
Even applying the remedy that the message suggests won't permanently resolve the issue. For that, you need to edit /etc/sysctl.conf with superuser access and add the following line to it:
fs.inotify.max_user_watches = 100000
With that in place, you can issue the following command to sort out the problem in the current session (assuming your user account is listed in /etc/sudoers):
sudo sysctl -p & dropbox stop & dropbox start
A reboot should demonstrate that the messages no longer appear again. For a good while, I had ignored it, but curiosity eventually got me to find out how it could be stopped and led to what you find above.
A place for GNOME?
21st September 2012There has been a lot of doom and gloom spoken about the GNOME desktop environment and the project behind it. These days, it seems to be the fashionable thing to go constantly criticising it, especially after what Linus Torvalds said. KDE went through the same sort of experience a few years ago and seems to have got far enough beyond it that some are choosing it instead of GNOME. For a good while, it was the other way around.
Since its inception, the GNOME Shell has attracted a lot of adverse comment. However, since my first encounter, it has grown on me to the point that I added it to Ubuntu and Linux Mint and use it as my default desktop environment instead of Unity, Mate or Cinnamon. The first of these may not be so surprising because of the unique approach that has been taken. The use of lenses and an application launch bar are items to which I could adapt, but it is the merging of application menus and title bars with the top panel of the desktop that really puts me off it. Application window buttons can be moved to the right everywhere but on this global menu, so I tend to view things from afar instead of using it every day. There just is something about the experience that won't grow on me. Strangely, that also applies to my impressions of KDE, albeit differently; there just is something less slick about the appearance of the bottom panel, the plasmoids and other items like them.
Given that Mate and Cinnamon continue the GNOME 2 approach to things that dominated my home computing for much of the last five years since I turned to Ubuntu, my decision to use GNOME Shell instead of either come as a surprise. It isn't that the environments aren't slick enough, just that I have come to prefer the way that GNOME Shell handles workspaces, spawning them as you need them. If that could be an option in Cinnamon, then it might become my desktop of choice. However, that seems to go against the philosophy of the project, even if someone adds and extension for it.
For a time, I played with going with LXDE rather than either Unity or GNOME Shell; as it happened, my first impressions of the latter weren't so positive until I spent a day with the GNOME variant of Fedora 15. Being not dissimilar to GNOME 2 in the way that it worked was the main attraction of LXDE and my initial use of it was with Lubuntu running on a netbook; the LXDE version of Linux Mint 12 now runs on it so there hasn't been so much change on that machine.
Sometimes, the only way to deal with change is to have a look at it to see what's coming and to decide what you need to do about it. In the case of GNOME Shell, my day with Fedora 15 on a backup PC changed my impressions, and Linux Mint 11's GNOME 2 desktop looked a bit old-fashioned afterwards. In fact, I popped GNOME 3 on there and have been using it as my main desktop environment ever since.
With computing, there always are some who expect things to just work and be the way that they want them. The need for extra configuration is a criticism that still can be levelled at GNOME Shell. Before going with Mate and Cinnamon, Linux Mint went the same way for a while, leaving me to wonder what can be done with such an approach. Will someone else pick up that baton and do the handiwork so that users don't have to do it? Not yet, it seems. Since no one is following the lead of Linux Mint 12, the need for user tweaking remains, even if I have found which ones work for me.
The first place to begin is GNOME's Extensions website, from where I raid a few extensions every time I do an operating system installation. The Alternative Status Menu extension is among the first to get added so that I have the shutdown option again on the user menu, a common criticism of the default set up. Since I always install the GNOME Tweak Tool from the distro repositories, I add the Advanced Setting in User Menu extension to get an entry in the status menu that grants quick access. Frippery Bottom Panel comes next on the list because of its workspace switcher and application window list. Others like Frippery Move Clock, Monitor Status Indicator, Places Status Indicator, Removable Drive Menu, Remove Accessibility, Shell Restart User Menu Entry and User Themes follow in some order and make things feel more pleasing, at least to my mind.
You aren't stuck with the default theme, either, and I have chosen Elementary Luna from deviantART. For adding your own themes, the above listed User Themes extension is needed. Because I want the Frippery Bottom Panel to match the top panel, I tweaked its stylesheet and that's where the Restart User Menu Entry extension comes in handy, though some care is needed not to crash the desktop with constant shell restarts.
Doing the above makes GNOME Shell really amenable to me, and I wouldn't like to lose that freedom to customise. Saying that, the continued controversial changes aren't stopping yet. Those made to the Nautilus file manager in GNOME 3.6 have caused the Linux Mint project to create Nemo, a fork of the software, and Ubuntu is sticking with the previous version for now. Taking some action yourself instead of just complaining loudly sounds like a more positive approach, which makes its own statement. However, at a time when many want the GNOME project team to listen to users, the new Nautilus appears and is not to be what they needed to see. Could the project go on like this? Only time can answer that one.
While it appears that many have changed from GNOME to other desktop environments, I haven't come across any numbers. A reducing user base could be a way of sending a message about any discontent, one that makes use of a great feature of free software: there is plenty of choice. If the next version of Nautilus isn't to my taste, there are plenty of alternatives out there. After all, Cinnamon started on Linux Mint and has gone from there to being available for other distros too; Fedora is one example. Nemo could follow suit.
Now that GNOME's constituent applications are seeing changes, GNOME Shell may be left to mature. Computer interfaces are undergoing a lot of change at the moment and Microsoft Windows 8 is bringing its own big leap. Though controversial at the time, change can be a good thing too and us technical folk always like seeing new things come along (today saw the launch of the iPhone 5 and many folk queueing up for it; Google's Nexus 7 ran out of stock in its first weeks on the market; there are more). That could be what got me using GNOME 3 in the first place, even if my plan is to stick with it for a while yet.
