When I upgraded to Karmic, some things broke. Here's what broke, and here's how I fixed it.
The very first thing I noticed was that I was not able to
start my beloved window manager xmonad
.xsession file; the option was conspicuously
missing from the set of allowed sessions.
As it turns out, the Gnome developers decided that Xsession should not be an option by default, and that system administrators should manually install a package that adds support for it. Ubuntu, of course, was blithely unaware.
After a lot of experimentation (and a wrong desktop file supplied by
Ray Strode), creating the file
/usr/share/Xsessions with the following
contents fixes the problem:
[Desktop Entry] Name=Xsession Comment=This runs ~/.xsession Exec=/etc/X11/Xsession
Because I run a custom
.xsession file, a lot of machinery
in Gnome was in a half-baked state. The screensaver stopped working
after the upgrade; this was identified to be because
no longer spawns this process; you'll have to manually load
gnome-screensaver. Curses gnome-settings-manager for having
some red herring errors that threw me off while debugging.
My power button no longer powered off my laptop. This was fixed by manually finding the power settings and telling it to "power off" when the power button was pressed, instead of asking the user. I have no idea why the dialog was not spawned in the earlier case.
iwl3945 decided to totally crap out on me, and refused to associate with the network using wpa_supplicant. Noting that network manager was managing to associate correctly, I bit the bullet and switched back to using network manager, using stalonetray to store the icon.
As the proud owner of an X61 Thinkpad Tablet, I have a number of
scripts set up to give myself auto-rotation when I switch to tablet
mode (graciously stolen from this page.)
As it turned out,
xrandr decided that the default screen
should be called LVDS1, instead of LVDS; so those hard-coded values
had to be changed.
I use Gnome on my desktop, partially because I've been too lazy to install XMonad, and partially because the mouse pattern of usage is much more natural for what I use my desktop for (checking the weather, checking email, etc.) It looks like a default got turned off from Jaunty to Karmic, namely, the ability to scroll from one desktop to another using your scroll wheel. Well, that won't do: load up "CompizConfig Settings Manager" in Preferences, navigate to "Viewport Switcher", select the "Desktop-based Viewport Switching" tab and use "Button 4" and "Button 5" to re-enable these bindings.
- Xmonad boots up very quickly; much more quickly than
xsplashthinks you should. Give
xsplashthe boot: you can remove it by commenting out the relevant lines in
- Karmic becomes very unhappy if you boot into a non-Karmic kernel. Don't try it.
