[Disclaimer: This is a crosspost from forums.opensuse.org. I did not receive any answer there.]

I am trying to use the proprietary catalyst driver with my ATI Mobility Radeon HD 3650 chipset on an HP Elitebook 8530p on a newly installed openSUSE 11.1.

Version 8.11 of the driver installs fine, X starts up fine, but it is running quite unstable (frequent crashes when playing video, switching consoles,...).

But when installing a newer driver (8.12 or 9.1) the machine crashes on the startup of X (under Gnome and KDE 4.x, under GDM and KDM), leaving a blank screen and an unresponsive machine. I used the same procedure to install 8.11 and 8.12/9.1: Download driver, run, ati-config --initial (I tried with and without sax2 -r -m 0=fglrx).

I also tried to replace /etc/ati/amdpcsdb with /etc/ati/amdpcsdb.default.

Does somebody have any idea, on what I am doing wrong? Or did I find a bug in the driver itself?

In the Xorg.0.log file I find (for 8.12) the following lines:
Code:
Backtrace:
0: /usr/bin/X(xf86SigHandler+0x79) [0x80c0c19]
1: [0xffffe400]

Fatal server error:
