I recently bought a barebone with Ubuntu 11.04 64 bits installed, which worked correctly except that the video worked a bit bad. So i tried downloading ATI Catalyst from ATI web, and tried to install. As Ubuntu asked me to uninstall first the old Catalyst or force the intallation, I tried forcing, and then after rebooting, the system freezes and shows a failure saying automatic crash report generation.

Then i tried rebooting in safe mode, wich works correctly, and try to reinstall ATI, but shows an error at installation. Rebooting the system, it now show a black screen, and does nothing. Please, i need help, as i am not a regular user of Ubuntu, and now i cant use the pc.

What error message ? – bodhi.zazen Jan 6 '12 at 21:16
I had the same problem. I ended up reinstalling Ubuntu and just using the ATI driver from the restricted drivers manager, didn't bother updating it. At the moment I'm using Gnome-Classic, I would like to have the driver updated in order to use Gnome-Shell, though. – titaniumtux Jan 6 '12 at 21:26
I Had the same problem, ended up re-installing. Sorry. :( – James Jan 7 '12 at 14:48

Unfortunately, the only "solution" that I've seen when I had to do this (and the comments above back me up) is to re-install Ubuntu without wiping the harddrive.
