With Linux distributions offering you everything on a plate, there is a temptation to stick with what they offer rather than taking things into your own hands. For example, Debian’s infrequent stable releases and the fact that they don’t seem to change software versions throughout the lifetime of such a release means that things such as browser versions are fixed for the purposes of stability; Lenny has stuck with Firefox 3.06 and called it Iceweasel for some unknown reason. However, I soon got to grabbing a tarball for 3.5 and popped its contents into /opt where the self-contained package worked without a hitch. The same modus operandii was used to get in Eclipse PDT and that applied to Ubuntu too until buttons stopped working, forcing a jumping of ship to Netbeans. Of course, you could make a mess when veering away from what is in a distribution but that should be good enough reason not to get carried away with software additions. With the availability of DEB packages for things like Adobe Reader, RealPlayer, VirtualBox, Google Chrome and Opera, keeping things clean isn’t so hard. Your mileage may vary when it comes to how well things work out for you but I have only ever had the occasional problem anyway.

What reminded me of this was a recent irritation with the OpenOffice package included in Ubuntu 9.10 whereby spell checking wasn’t working. While there were thoughts about is situ fixes like additional dictionary installations, I ended up plumping for what could be called the lazy option: grabbing a tarball full of DEB packages from the OpenOffice website and extracting its contents into /tmp and, once the URE package was in place, installing from there using the command:

dpkg -i o*

To get application shortcuts added to the main menu, it was a matter of diving into the appropriate subfolder and installing from the GNOME desktop extension package. Of course, Ubuntu’s OpenOffice variant was removed as part of all this but, if you wanted to live a little more dangerously, the external installation goes into /opt so there shouldn’t be too much of a conflict anyway. In any case, the DIY route got me the spell checking in OpenOffice Writer that I needed so all was well and another Ubuntu rough edge eradicated from my life, for now anyway.

One of the things that stopped working as it should after my recent Ubuntu 9.10 upgrade was the Eclipse PDT installation that I had in place. Editing files went a bit haywire and creating projects had me pushing buttons with nothing happening. Whether this was a Java or GNOME issue, I don’t know but I found it happening too on openSUSE 11.2 (there should be more on that distro in a later entry). That was enough to get me looking again at Netbeans.

In both openSUSE (NB version 6.5) and Ubuntu (NB version 6.7.1), I plucked the default offering of Netbeans from the respective software repositories and added the PHP plugin in both cases. Unlike when I last gave the platform a go, things seemed to go smoothly and it looks to have replaced Eclipse for PHP development duties. Project scanning make take a little while but it’s far from annoying and my earlier dalliance with using Netbeans as a PHP editor was stymied by performance that was so sluggish as to make the thing a pain to use. Up to now, Netbeans’ footprints when it comes to its use of PC power never was light so I am wondering if dual-core and quad-core CPU’s help along with a copious supply of RAM. Only time will tell if these inital positive impressions stay the course and I’ll be keeping an open mind for now.

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.

After moving to Ubuntu 9.10, Brasero stopped behaving as well as it did in Ubuntu 9.04. Any bootable disks that I have created with it weren’t without glitches. After a recent update, things got better with a live CD actually booting up a PC rather than failing to find a file system like those created with its forbear. While unsure if the observed imperfections stemmed from my using the RC for the upgrades and installations, I got to looking for a solution and gave K3b a go. It certainly behaves like I’d expect it and a live CD created with it worked without fault. The end result is that Brasero has been booted off my main home system for now. That may mean that all of the in-built GNOME convenience is lost to me but I can live without the extras; after all, it’s the quality of the created disks that matters.

One of the early signs that I noticed after upgrading my main PC to Ubuntu 9.10 was a warning regarding the health of one of my hard disks. Others have reported that this can be triggered by the least bit of roughness in a SMART profile but that’s not how it was for me. The PATA disk that has hosted my Ubuntu installation since the move away from Windows had a few bad sectors but no adverse warning. It was a 320 GB Western Digital SATA drive that was raising alarm bells with its 200 bad sectors.

The conveyor of this news was Palimpsest (not sure how it got that name even when I read the Wikipedia entry) and that is part of the subject of this post. Some have been irritated by its disk health warnings but it’s easy to make them go away by turning off Disk Notifications in the dialogue that going to System > Preferences > Startup Applications will bring up for you. To fire up Palimpsest itself, there’s always the command line but you’ll find it at System > Administration > Disk Utility too. My complaint about it is that I see the same hard drive listed in there more than once and it takes some finding to separate the real entries from the “bogus” ones. Whether this is because Ubuntu has seen my SATA drives with SIL RAID mappings (for the record, I have no array set up) or not is an open question but it’s one that needs continued investigation and I already have had a go with the dmraid command. Even GParted shows both the original /dev/sd* type addressing and the /dev/mapper/sil_* equivalent with the latter being the one with which you need to work (Ubuntu now lives on a partition on one of the SATA drives which is why I noticed this). All in all, it looks less than tidy so additional interrogation is in order, especially when I have no recollection of 9.04 doing anything of the sort.

A little while, I encountered a problem with ImageMagick processing DNG files in Ubuntu 9.04. Not realising that I could solve me own problem by editing a file named delegates.xml, I took to getting a Debian VM to do the legwork for me. That’s where you’ll find all the commands used when helper software is used by ImageMagick to help it on its way. On its own, ImageMagick cannot deal with DNG files so the command line variant of UFRaw (itself a front end for DCRaw) is used to create a PNM file that ImageMagick can handle. The problem a few months back was that the command in delegates.xml wasn’t appropriate for a newer version of UFRaw and I got it into my head that things like this were hard-wired into ImageMagick. Now, I know better and admit my error.

With 9.1o, it seems that the command in delegates.xml has been corrected but another issue had raised its head. UFRaw 0.15, it seems, isn’t the speediest when it comes to creating PNM files and, while my raw file processing script works after a spot of modification to deal with changes in output from the identify command used, it takes far too long to run. GIMP also uses UFRaw so I wonder if the same problem has surfaced there too but it has been noticed by the Debian team and they have a package for version 0.16 of the software in their unstable branch that looks as if it has sorted the speed issue. However, I am seeing that 0.15 is in the testing branch so I’d be tempted to stick with Lenny (5.x) if any successor turns out to have slower DNG file handling with ImageMagick and UFRaw. In my estimation, 0.13 does what I need so why go for a newer release if it turns out ot be slower?
