Karmic KoalaUbuntu 9.10 (Karmic Koala) is out, so I decided to upgrade. The upgrade process itself went fine, but it seems there were some other changes to the system, which affected me.
I'm running on a MacBook Pro Santa Rosa with 4 GB mem, which means that if I use the standard 32 bit kernel, I cannot use all of the memory. That's not really a problem, I just recompile the kernel to support PAE.
However, I also use XMonad (because it's the best window manager available), and previously I launched it from ~/.xsession. However, the new version of GDM doesn't support that anymore, so now you have to drop a file in /usr/share/xsessions/xmonad.desktop - mine contains this:
-
[Desktop Entry]
-
Encoding=UTF-8
-
Name=xmonad
-
Comment=xmonad
-
Exec=/pack/haskell/bin/runxmonad.sh
-
Type=Application
Other than that, simply follow this little guide to make the keyboard and touchpad work properly.
