Description Michal Marek 2010-12-17 11:56:20 UTC 
I have
00:02.0 VGA compatible controller [0300]: Intel Corporation 82G35 Express
Integrated Graphics Controller [8086:2982] (rev 03)
00:02.1 Display controller [0380]: Intel Corporation 82G35 Express Integrated
Graphics Controller [8086:2983] (rev 03)

as reported at https://bugzilla.novell.com/658802 and in bug 30637, X displays a corrupt xdm screen on startup. The machine works otherwise, but the corrupt screen stays even if I switch to tty1.
