Pater Phil: Thank you so much! That solved my problem. Of course, as I expected, Unity still doesn't work, but I have the same acceptable 3d acceleration of Lucid (I can see glxgears and use compiz and 3d applications like stellarium).
I didn't know anything about kernel mode-setting. I thought that the radeon driver was the responsible of my problem. Of course, when I turn off KMS, some tasks are somewhat slower (specially during logins, logouts and when I change user). I will mark this bug as invalid and I will report a bug against the Linux kernel package here in Launchpad. -- Unusable 3d acceleration on Maverick (ATI Radeon X1200) https://bugs.launchpad.net/bugs/665991 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
