It seems the OpenSUSE updater upgraded the Nvidia drivers to version 169.07 but it broke Compiz in the process.
After some exhaustive googling I found the solution in this blog. It's in Italian and it seems meant for Ubuntu users but the code snippets were easy enough to follow and they worked for me on OpenSUSE 10.3
After installing the updates and rebooting, I noticed that compiz wasn't working anymore so I manually executed compiz from a gnome terminal and got this error ....
“No GLXFBConfig for default depth”
The solution according to M0rF3uS’ Ubuntu Blog is to execute the following in your terminal
LIBGL_ALWAYS_INDIRECT=1 compiz -–no-libgl-fallback -–replace ccp &
Alternatively, if you use fusion-icon to launch compiz, open the file
and locate the line with compiz_args.
edit it so that it looks like
compiz_args = [’–replace’, ‘–sm-disable’, ‘–ignore-desktop-hints’, ‘ccp’, ‘–no-libgl-fallback’]
Then, open a terminal and execute
UPDATE: This latest version of the NVIDIA drivers fixed the function keys that control the brightness on my T61. This means that I don't have to exit X windows anymore to adjust the brightness.
