Rough?

11th November 2009

Was it because Canonical and friends kept Ubuntu in such a decent state from 8.04 through to 9.04 that things went a little quiet in the blogosphere on the subject of the well-known Linux distribution? If so, 9.10 might be proving more of a talking point and you have to wonder if this is such a good thing with the appearance of Windows 7 on the scene. Looking on the bright side, 10.04 will be an LTS release so there is some chance that any rough edges that are on display now could be resolved by next April. Even so, it might have been better not to see anything so obvious at all.

In truth, Ubuntu always has had its gaps and I have seen a few of their ilk over the last two years. Of these, a few have triggered postings on here. In fact, issues with accessing the BBC iPlayer still bring a goodly number of folk to this website. That may just be a matter of grabbing RealPlayer, now helpfully available as a DEB package, from the requisite place on the web and ensuring that Ubuntu-Restricted-Extras is in place too but you have to know that in the first place. Even so, unexpected behaviours like Palimpsest seeing every partition on a disk as a different drive and SIL Raid mappings being seen for hard drives that used to live on the main home PC that bit the dust earlier this year; it only happens on one of the machines that I have running Ubuntu so it may be hardware thing and newly added hard drive uses none of the SIL mapping either. Perhaps more seriously (is it something that a new user should be encountering?), a misfiring variant of Brasero had me moving to K3b. Then UFRaw was sluggish in batch but that’s nothing that having a Debian VM won’t overcome. Rough edges like these do get you asking if 9.10 was ready for the big time while making you reluctant to recommend it to mainstream users like my brother.

The counterpoint to the above is that 9.10 includes a host of under the bonnet changes like the introduction of Ext4 hard drive formatting, Xsplash to allow the faster system loading to occur unseen and GNOME 2.28. To someone looking in from outside like me, that looks like a lot of work and might explain the ingress of the annoyances that I have seen. Add to that the fact that we are between Debian releases so things like the optimised packaging of ImageMagick or UFRaw may not be so high up the list of the things to do, especially with the more general speed optimisations that were put in place for 9.10. With 10.04 set to be an LTS release so I’d be hoping that consolidation is the order of the day over the next five or six months but it seems to be the inclusion of new features and other such progress that get magazine reviewers giving higher ratings (Linux Format has given it a mark of 9 out of 10). With the mooted inclusion of GNOME 3 and its dramatically different interface in 10.10, they should get their fill of that. However, I’d like to see some restraint for the take of a smooth transition from the familiar GNOME 2.x to the new. If GNOME 3 stays very like its alpha builds, then the question as how users will take to it arises. Of course, there’s some time yet before we see GNOME 3 and, having seen how the Ubuntu developers transformed GNOME 2.28, I wouldn’t be surprised if the impact of any change could be dulled.

In summary, my few weeks with Ubuntu 9.10 as my main OS have thrown up no major roadblocks that would cause me to look at moving elsewhere; Fedora would be tempting if that situation were to arise. The irritations that I have seen are more like signs of a lack of polish and remain peripheral to day-to-day working if you discount CD/DVD burning. To be honest, there always have been roughnesses in Ubuntu but has the lack of sizeable change spoilt us? Whatever about how things feel afterwards, big changes can mean new problems to resolve and inspire blog posts describing any solutions so it’s not all bad. If that’s what Canonical wants to see, they might get it and the year ahead looks as if it is going to be an interesting one after a recent quieter period.

Seeing how things develop

7th October 2009

One of the things that I do out of curiosity and self-interest is to keep tabs on what is happening with development versions of software that I use. It is for this reason that I always have a development version of WordPress on the go so as to ensure that the next stable version doesn’t bring my blog to its knees. There have been contributions from my own self to the development effort, mainly in the form of bug reports with the occasional bug fix too.

In the same vein, I have had a development version of Ubuntu installed in a VirtualBox virtual machine. There have been breakages and reinstallations along the way when an update results in disruption but it is intriguing too to see how a Linux distribution comes to fruition. In the early days of Karmic Koala (9.10), everything was thrown together more loosely and advances looked less obvious. It is true to say the ext4 file systems support was already in place but the interface looked like a tweaked version of the standard GNOME desktop. Over time, the desktop has been customised and boot messages hidden out of sight. Eye candy like new icons and backgrounds have begun to entice while other features such as an encrypted home folder, Software Store and Ubuntu One came into place. Installation screens became slicker and boot times reduced. All of this may seem incremental but revolutions can break things and you only have to look at the stuttering progress of Windows to see that. Even with all of these previews, I still plan to do a test run of the final revision of 9.10 before committing to putting it in place on my main home PC. Bearing the scars of misadventures over the years has taught me well.

Windows development is a less open process but I have been partial fo development versions there too. In fact, beta and release candidate installations of Windows 7 have convinced me to upgrade from Windows XP for those times when a Windows VM needs to fired up in anger. A special offer has had me ordering in advance and sitting back and waiting. With my Windows needs being secondary to my Linux activities, I am not so fussed about taking my time and I have no intention of binning Windows XP just yet anyway.

The trouble with all of this previewing is that you get buffeted by the ongoing development. That is very true of Ubuntu 9.10 and has been very much part and parcel of the heave that brought WordPress 2.7 into being last year. Things get added and then removed as development tries to fins that sweet spot or a crash results and you need to rebuild things. It is small wonder that you are told not to put unfinished software on a production system. Another consequence might be that you really question why you are watching all of this and come to decide that what you already have is a place of safety in comparison to what’s coming. So far, that has never turned out to be true but there’s no harm in looking before you leap either.

An early peek at Ubuntu 9.10

5th August 2009

Even if the twice a year release means that changes to Ubuntu are evolutionary rather than revolutionary, that isn’t to say that curiosity doesn’t get the better of me from time to time. The result is that an early alpha version (3 at the time of writing) of the Linux distro has found a home in a VirtualBox VM on my main system. The most noticeable change so far is the inclusion of GNOME 2.27.5 with its Fedora-esque log-in screen and the movement of the shutdown and log-off paraphernalia to the System menu, which is where you find it in Debian or Fedora. On the account settings menu, there lives a link to an equivalent of the Windows Control Panel called Control Centre; the menu item is named System Preferences. For the record, I have seen it in Fedora 11 too and it does look as if Ubuntu’s GNOME implementation is looking more like a brown equivalent of Fedora. Whether this stays is anyone’s guess but a new messaging arrangement is coming into being too.

Otherwise, there appears to be no real drama on the surface with Firefox staying at 3.0.x for now and OpenOffice moving to 3.1. Personally speaking, I’d be very surprised to seeing Firefox 3.5.x being left out though I did run into a spot of bother with the Preferences dialogue crashing it on Windows XP. Under the bonnet, the kernel is at release 2.6.31 and things seem reasonably stable at this stage. Saying that, there is a crash report icon appear every session but that has no effect apart from the visual side of things. VirtualBox Guest Additions work as they should, better than they in Windows guests if my experience provides any sort of benchmark (the display does odd things unless you keep jogging the graphics memory up and down). All in all, things appear usable if undramatic at this stage and there are a few months to go before the final release anyway.

Ubuntu upgrades: do a clean installation or use Update Manager?

9th April 2009

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.

An early glimpse of Ubuntu 9.04

27th November 2008

Ubuntu development is so gradual these days that there’s almost no point getting too excited about new versions. Its being a mature Linux distribution means that updates aren’t that much of an upheaval and I must admit to liking it than way. Taking a look at the first alpha release of Ubuntu 9.04, otherwise known as “Jaunty Jackalope”, it seems that there isn’t a change to that gradual, some may call it glacial, approach. The biggest change that I noted was the addition of an encrypted private area to your home user area. In the times in which we live, I can certainly see that coming in useful though it may not set pulses racing in some quarters. OpenOffice is still at 2.4 and things don’t appear very different on the surface at all. Of course, things like kernel changes and such like could be going on under the bonnet without many of us noticing it.Saying that, it played well with VirtualBox and I seem to remember virtual machine trouble with early builds of 8.10 so that can be taken as a plus point. I suppose that it is a case of wait and see before there is anything more obviously defining about 9.04. Anyway, they’ve got until April next year…

Another alpha release of Ubuntu 8.10 is out

26th July 2008

It’s probably about time that I drew attention to Ubuntu’s The Fridge. While the strap line says “News for Human Beings”, it seems to be the place to find out about development releases of the said Linux distribution. Today, there’s a new alpha release of Intrepid Ibex (8.10) out and they have the details. As for me, I’ll stick to updating my 8.10 installation using Synaptic rather than going through the whole risky process of a complete installation following a download of the CD image. Saying that, it would be nice to see the System Monitor indicating which alpha release I have. I didn’t notice anything very dramatic after I did the update, apart maybe from the hiding away of boot messages at system startup and shutdown or the appearance of a button for changing display settings in the panel atop the desktop.

A first look at Ubuntu 8.10

20th July 2008

I must admit that my curiosity got the better of me when screenshots of Ubuntu’s 8.10, otherwise known as Intrepid Ibex, started to make their appearance. It is only at alpha2 stage so it’s definitely a no-no for production systems. However, it does run surprisingly smoothly even at this stage. Yes, I have seen rough edges and the biggest of them all has made me install it onto my spare PC; there is certainly tendency for systems to hang when you try running 8.10 in virtual machines, my preferred method for these kinds of explorations. Try it in VirtualBox and kernel panic messages ensue while you can log in on VMware Workstation only for the desktop never to load. Those could be major deficiencies for some but they have both been reported with the former being seen by many and the latter being flagged by my own self.

Because I was using a version with the alternate installer, the usual slickness that we expect of Ubuntu installations wasn’t apparent. I am sure that will change in time for the final release but I didn’t find it too taxing to get things going with this means. Nevertheless, I reckon that we will see the usual feel return in later development versions and very much in time for the final release. Because I was installing over the top of a previous Ubuntu installation, I didn’t want to lose everything but I needed to leave it wipe out the previous root system partition for it to continue without freezing. Because my home area is on a separate partition, there was no problem and it picked up settings like desktop backgrounds without a fuss. One thing that might annoy some is that all this takes manual intervention; you don’t get the sort of non-destructive and seamless upgrade capability that openSUSE 11 gives.

What you get when the installation is completed is a Linux desktop that won’t look too different from what we are used to using. Of course, we get the New Human theme with its tasteful chocolate tones in place of the previous default orangey browns. They need to sort out a bug (another of my reports)  where black text is being displayed on dark backgrounds on the default display of drop down menus in Firefox and maybe look into why changing the level of enhancements from Compiz Fusion messes up the display of the workspace switcher in the task bar but it’s fine apart from this.

Otherwise, it’s a case of steady as she goes with OpenOffice 2.4, Firefox 3 and so on. That may change as time goes on OpenOffice 3 looming in the horizon. For some, all this continuity is all well and good but I could foresee comments front some parts that nothing dramatic is happening and that Ubuntu cannot afford to stand still with the advances of Fedora, openSUSE, Mandriva and so on. Saying that, I personally like the continuity because it doesn’t mean that my apple cart is going to get overthrown now and again. Indeed, you could say that the whole Linux distribution market has matured very nicely with evolution being the order of the day and I suppose that Ubuntu needs to be seen to be evolving more than perhaps it has been doing.

In summary, it’s early days for Intrepid Ibex but it works well even at this stage. In fact, it is running sufficiently so that I am writing this very post in a Firefox session running on the thing.  It’ll be interesting to see how it goes from here and if any more pleasant surprises are visited upon us. After the “safety first” approach of Hardy Heron, I suppose that Canonical can feel a little more adventurous so we’ll see what comes. In the meantime, Here are a few screenshots below for your perusal:

An introduction to Wubi

14th July 2008

An introduction to Wubi

The Toshiba laptop that I acquired at the start of the year is a Windows Vista box and it isn’t something with which I want to play too roughly because the OS came pre-installed on it. I still want to continue to see how Vista goes at close quarters so removing it to put Ubuntu or some other Linux distribution on there wasn’t ever going to be an option that I was willing to take either. Neither was the option of setting up a dual booting arrangement using disk partitioning; I have plenty of experience of doing that to set up dual booting machines over the years and I don’t needed any more than what I already have. So, I was happy to leave it as a Windows box and only as a Windows box.

That situation has changed and the cause was Canonical’s decision to go for something novel when it brought out Ubuntu 8.04. The premise is as follows: a Windows style installation that popped an entry in the Windows boot menu that allowed you to fire up Ubuntu without ever having to do disk partitioning or other similar rough play. For those who are less than enamoured with the Linux option, it’s even easy to remove too, as easy any other Windows program in fact. Removal of Linux is very definitely not what I’d do and that’s even without the pain and upheaval of more more customary means for setting dual booting machines. In these days of virtualisation and hypervisor technology, I have my ideas as to what has been used to give us that easy way in.

Being an Ubuntu user anyway, the possibility of having Ubuntu on the laptop and the interesting opportunity that Wubi offered for getting it on there was too tempting for me to give it a miss. A small download from the Wubi website is all that is needed to set things off. You get a number of options up front like where to put the (large) file to be used to house the Ubuntu world and how large you might want it. Setting a user name and password for the thing gets included among other items. The next stage is to download the files to be used to perform the installation. Once that is completed and it took me a few goes to get the whole lot (thankfully, it stores things up to the point where the downloading operation cuts out so you didn’t start from scratch each time; even so, it’s still annoying and could put some off), it is time to restart the computer and boot into Ubuntu to complete the set up of the operating system itself; it is at this point that the familiar very much returns. A reboot later and you are into a world that does its level best to fool you into thinking that Windows is another universe and never existed on that machine at all.

So, a machine that seemed destined only ever run Windows can run Linux now as well. Wubi comes across as a neat and clever way to get a dual booting computer and I hope to leave mine as I now have it. No feathers were ruffled on the Windows side and I saw no sign of any destruction. That makes Ubuntu’s way of doing things a much better option than other distributions that make you go down more invasive routes when creating a dual booting PC. A question remains in my mind. Could this approach take off?

A move to Ubuntu?

30th October 2007

After a pretty rotten weekend attempting to keep Windows XP running, I finally lost the will to persevere and began yearning for stability. That has taken me into the world of Ubuntu; I am writing this in Firefox running on the said Linux distribution. Thanks to the wonders of VMware, I have been able to observe the swish and slick nature of Ubuntu and I must that it did sway me. Installation has been slick and efficient and is a dream compared to XP, let alone previous Linux incarnations that I have encountered over the years. Start up is also speedy. All in all, there seems to be a certain confidence about the OS that was sadly absent from my Windows experience in recent times.

I am not deserting the world of Windows completely though. As it happens, I installed Ubuntu on a spare hard drive that I had so the Windows installation is still out there. In addition, VMware virtual machines should allow me to stay in there without the ever present risk of a PC getting rendered inoperable. There is also the unfinished business of making myself at home in Ubuntu, hopefully without my wrecking anything. I have yet to give my hardware a full work out to check that all is well. Setting up a web development capability is also on the cards as is getting those virtual machines. Assuming that there are no show stoppers, it could be an interesting ride.
