I have exactly the same problem with my HD4670. I've been commenting about this on bug 387013 but I'll start interacting on this one instead. Let me know if there's anything useful I can post about it (my xorg log file is posted over there).

Returns to gdm which then hangs. https://bugs.launchpad.net/bugs/427101 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 : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
