After commenting out the fglrx line in /etc/modules and rebooting, 3D acceleration still works. No Mesa here. So all you need to do apparently is follow that guide.
I guess it should be more automatic though. Especially if AIGLX is compiled into Ubuntu's Xorg and fglrx does not yet support it. If someone chooses fglrx in dpkg-reconfigure xserver-xorg the disabling of Compositioning should be done automatically. -- Edgy Eft - fglrx module not started https://launchpad.net/bugs/57716 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
