Can you try switching DRI off. You can download the attached Xorg.conf file and put in in /etc/X11. Then log off and back on again.
If the server works with DRI switched off, then that is this bug. If it doesn't you'll need to log another one with 'ubuntu-bug xserver-xorg- video-ati' as it may be something different. ** Attachment added: "ATI Radeon Xorg.conf" http://launchpadlibrarian.net/31285370/xorg.conf -- X server fails with DRI : drmRadeonCmdBuffer: -22 https://bugs.launchpad.net/bugs/419434 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
