Comment 3 for bug 188409

I can confirm this bug. I believe the description is somewhat misleading, though. As far as I know, the xorg.conf is supposed to be "bare-boned" in hardy to let xorg detect the hardware automatically. This is what fails horribly for me as well, with the same symptoms. X starts up in failsafe mode since no suitable configuration is found by the autodetection. My hardware is a Mobility Radeon X600 which is supposed to be supported by the latest fglrx driver and my screen is a Dell Laptop display at 1920x1200.
I have no real clue how the autodetection is supposed to work, but I guess that xresprobe is no longer used. Perhaps the output of ddcprobe and get-edid is of some help?
