I posted in lavinog's thread also as we are seemingly having the same symptoms with similarish hardware. I tried a few things that I described in the thread.
To make it short. Does not seem to matter if I use updates from xorg-edgers, natty proposed updates and kernel PPA, kernel 2.6.39.05. - 11.04 LiveCD > reboot or poweroff as soon as X/GUI is started. - Installed via alternate Install CD - at GDM login within about 1 second reboot. - in recovery mode as root, "X -configure" gives errors and fails - in recovery mode as root, "startx" functions, get a desktop wallpaper and can add starters to the desktop. - in X as root can add a starter for a terminal - when as root starting unity from a terminal in X the Unity desktop works as it should (with effects and all) - in recovery mode as rood, "gdm" command causes a reboot as soon as the GUI is loaded. - Removed GDM, installed KDM/LXDE. KDM login screen ok, but as soon as logging in with my own username in any desktop environment > reboot. So single user (recovery mode) is ok, but multi-user (normal mode) fails? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/779323 Title: Xorg reboots with non-fglrx driver _______________________________________________ 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
