Created attachment 31490 [details] [review] radeon [9600AGP] Xorg.0.log I'm using the default KDE installation of OpenSUSE 11.2 (kernel 2.6.31.5-0.1; Xorg 7.4-35.3, KDE 4.3.1), Radeon 9600 AGP, DVI, Samsung 2493hm monitor. Kwin effects are disabled. The default installation does not create xorg.conf. Sometimes, after the system boots, X becomes unstable and starts to fade to black (blink / flicker) as soon as I actually start doing something: moving a mouse cursor, open a window, etc. When experiencing the bug, the screen flickers *every* time any rendering occurs. The first sign the above mentioned bug is about to occur is the initial "blink" of the KDE splash screen during boot. The bug occurs about 15%-20% of the times my system boots. The described "blinking" condition can be cured by restarting X or starting a new user session. There is a small chance, however, to initiate the bug if a new session is started in addition to the original "unbuggy" one. The bug was originally reported to Novell: https://bugzilla.novell.com/show_bug.cgi?id=555657

I suspect it's an AGP mode problem. Does changing the AGP mode help? Try the following option in the device section of your xorg.conf: Option "AGPMode" "X" where X = 1 or 2 or 4 or 8 Let me know which mode(s) work and the output of lspci -vnn and I'll add a quirk for your card.

The results are as follows. Option "AGPMode" "1" results: 5 normal boots, 5 buggy ones Option "AGPMode" "2" results: 8 normal boots, 2 buggy ones Option "AGPMode" "4" results: 8 normal boots, 2 buggy ones Option "AGPMode" "8" results: 8 normal boots, 2 buggy ones I've even conducted couple of unbuggy boots with an "AGPMode" "7" (which seems to be strange to me) Below I've attached my xorg.conf (just in case) and the output of lspci -vnn you've requested.

Does: Option "DisplayPriority" "HIGH" in the device section of your config help?
(In reply to comment #7) > Does: > Option "DisplayPriority" "HIGH" > in the device section of your config help? > Conducted 10 boots with 2 options (simultaneously) in place in the ati section: Option "AGPMode" "8" Option "DisplayPriority" "HIGH" The statistics were the same: 20% failure.
The bug is also initiated with AFAIK 20% success rate after the monitor exits power saving mode.
