Miscellaneous notes for Ubuntu 5.10 (Breezy)
If you dist-upgrade from Ubuntu 5.04 (Hoary) rather than installing 5.10, you might not get the new graphical splash screen during boot. This can be caused by the order that packages are upgraded -- the usplash package is needed before installing and setting up the LinuxKernel image. Ubuntu's Kernel uses an InitialRamDisk, and this needs to be recreated after usplash is installed. Anyway, the following command will do what you need:
dpkg-reconfigure linux-image-2.6.12-9-386
An amd64 setup would probably look something like:
dpkg-reconfigure linux-image-2.6.12-9-amd64-generic
That recreates the /boot/initrd.img-... file to use the splash image.
To get proper 3D/OpenGL hardware acceleration, see NvidiaDriverHowto.
GNOME uses X resources (via xrdb(1)?) to try to make older X11 programs look like the current GTK theme. However, figuring out where these are set is very difficult. GNOME's gnome-settings-daemon is responsible for loading default X resources files. In Ubuntu 5.10, these are the files in /etc/gnome/config/*. For example, the General.ad sets default foreground and background colours for all X apps, and this is what makes xterm(1) default to black-on-white. (In Gentoo, these files are in /usr/share/control-center-2.0/xrdb.)
You can also manually override all these settings yourself via the xrdb program, but any time the gnome-settings-daemon reloads, the defaults will be reloaded.
If you have done a dist-upgrade from Debian Sarge or Sid to Ubuntu 5.10, you may have noticed that you can no longer use Alt+Ctrl+[1-6] to change virtual consoles. This is a consequence of the switchover from xfree to xorg - in Debian, /etc/X11/xkb/symbols/pc is a directory while in Breezy it is a file. When Xorg can't load this file, it doesn't know what to do with some key codes. Delete this directory and copy this file over from another Breezy computer, or re-install the "xkeyboard-config" package. To re-install, you'll probably need to do something like
dpkg --force-depends --purge xkeyboard-config apt-get install xkeyboard-config
(By using dpkg --force-depends instead of apt-get or aptitude you won't end up removing other X and ubuntu-desktop packages). Once this file is properly installed, "/etc/init.d/gdm restart" is needed to get X to use it.
