Comment 29 for bug 118605

I am also experiencing this with Kubuntu 8.04 (AMD64). Video is ATI X1250 with latest fglrx (re-downloaded again yesterday, from Ubuntu repositories) and no compiz fusion. It consistently goes to black screen after logout or attempt to restart. The Ctrl-Alt-Fx keys and Ctrl-Alt-Backspace do not work, though Ctrl-Alt-Del will eventually bring back the splash logout screen if I repeat it a half dozen times. Using regular Vesa removes the problem, but I am unable to use any of the other ATI drivers (ATI Vesa, radeon) because the OS insists the card doesn't support it. If I try to select these anyway, I boot up to a black screen and have to restore settings from the command line. So, using the accelerated driver is my only option. fglrx works fine except as noted above, although I've had one instance in the last 10 days (since initial install) that the system froze during a GL screensaver.
