I dont have xorg.conf file anymore (because you said that I remove in other report).
I using the last update of mesa 7.6.0~git20090817.7c422387-0ubuntu1 and compiz works, but it is useless because it is extremely slow. If I move a window to the other corner of screen it cost 2 o 3 seconds to wait. Also I get a fatal error with compiz if metacity composite is enabled with Ubuntu Tweak: $ compiz --replace Checking for Xgl: not present. xset q doesn't reveal the location of the log file.
