A few notes on Ubuntu 11.04

Right off the bat, I have to say that I’ve been using 11.04 on one of my computers since one of the earliest alpha releases, so I’ve had the opportunity to watch it mature.  It’s something I often do – pick one computer, and use it to test out the new versions of ubuntu, upgrading the packages daily to follow along with the progress of the development. It’s usually a rewarding process, and I enjoy fixing bugs and learning how the operating system components fit together.

This was one of the few times that it was a disappointment for me.

Normally, I’ll start the process a month after the newest release, spending about two months using highly unstable versions, which then improve over time so that nearly all of the bugs are gone about a month before the official release.  This time, the release has come and gone, and my computer still doesn’t feel particularly useful.

Unlike the majority of Ubuntu users, I’m not using the default Ubuntu with Gnome window manager (or is it unity, now?), but rather KDE + Compiz.  Unfortunately, while the KDE version of Ubuntu (Kubuntu) doesn’t appear to get nearly as much attentention from the devs, it usually does march in lockstep, giving reasonable releases that come together at the last minute.  Unusually, compiz just never did come back together for me.  Perhaps it has to do with the upgrades to the xorg packages, but something is just not right when using compiz.

The symptoms are frequent restarts and crashes of the windowing system, in which the CPU usage of compiz soars to 100% and fails to respond to anything short of a the “killl -9” command.  Unfortunately, that makes compiz totally unuseable.  Ironically, it seems to happen only when closing windows, which seems like a strange place for a bug.

The workaround, if it’s actually a work around, is to completely disable compiz, which means switching back to the default KDE window manager.  Fortunately, it’s stable, so at least I can use the computer.  Unfortunately, I find Compiz to be a significant boost to my productivity, with the rotating cube desktop, the scale plugin, etc.  All of those things really make the experience on the computer, so turning all of them off it just unapealing.

In any case, for now, I’ll be staying with 10.10 on my laptops and production computers until compiz is fixed, with the possibility of jumpping straight to 11.10 as soon as that begins if I see compiz gets a bit more of the attention it deserves.

Your milage may vary, but 11.04 isn’t likely to make an appearance on my main computers anytime soon.
