I need some help with my ATI Driver

Hi all,
I’ve done quite some installations with openSuse, but somehow I never got the ATI drivers to work properly. Every time I try I get some other results. So I wanted to ask here for some help. I’ll just pretend to be even dumber than I really am, and maybe this may appear on the Wiki as a Tutorial :wink:

Anyway, just to be on the same page: I did a clean installation of openSuse 11.1 with KDE 3.5

# lspci | grep Radeon
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series

installing the PAE Kernel:

# uname -a
Linux legio #1 SMP 2009-03-31 14:50:44 +0200 i686 i686 i386 GNU/Linux

and the corresponding fglrx driver:

# rpm -qa | grep fglrx

everything went nicely, and the /etc/X11/xorg.conf has the following sections:

Section "Device"
        Identifier  "aticonfig-Device[0]-0"
        Driver      "fglrx"
        BusID       "PCI:1:0:0"

But still glxinfo kicks me with the following:

$ glxinfo | grep OpenGL
libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Mobility Radeon HD 3400 Series
OpenGL version string: 1.4 (2.1.8494 Release)
OpenGL extensions:

So what would you suggest doing next?

Oh and by the way: it’s a Thinkpad T400, which crashes X quite often :frowning:

Have you read through these wiki pages?

ATI - openSUSE

ATI/Troubleshooting - openSUSE

My guess is that the fglrx module is correctly installed as it appears in lsmod:

$ lsmod | grep fglrx
fglrx                2052260  31
agpgart                32308  2 fglrx,intel_agp

So it does indeed load and grepping for errors in the Xorg log doesn’t show anything.

I followed the repository instructions on Howto/ATI as for the troubleshooting guide I don’t think that any of those points applies as I don’t get any errors, except this:

$ glxgears
libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering
10519 frames in 5.0 seconds = 2101.906 FPS
