ATi Catalyst driver 8.1 problem on Slack 10.2


Hi,

I have the following problem.

I have installed the 8.1 drivers on my Slack 10.2 box. After a reboot, when I run 'fglrxinfo' as root, I get:

display: :0.0 screen: 0
OpenGL vendor string: ATI Tecnologies Inc.
OpenGL renderer string: Radeon X1900 Series
OPenGL version string: 2.1.7276 Release
However if I run it as a normal user, I get:
libGL error: open DRM failed (operation not permitted)
libGL error: Reverting to (slow) indirect rendering
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX indirect
OPenGL version string: 1.2 (1.5 Mesa 6.2.1)
This obviously affects applications like Google Earth.

Anybody know why it reverts to Mesa when used as a non-root user?

Thanks for your time,


M.

Check at the end of your xorg.conf and make sure that the following is UN-commented.
Code:
EndSection

 Section "DRI"
    Mode 0666
 EndSection

Hi Jeebiz,

Thank you for replying.

My xorg.conf file didn't have that section, so I added it and now all is well.

I'm now going to read up on how / why that fixed it.

Many thanks,


M.

Hi Jeebiz,

Does this need any support in the kernel?

The reason I ask is that I have just upgraded my kernel to 2.6.24 and I'm back to square 1. 'fglrxinfo' now displays the Mesa message again.

However, if I boot back into my 2.6.23 kernel, its all okay.

Neither kernel has Direct Rendering Manager support enabled.

Any thoughts?

The module, fglrx, was compiled for your 2.6.23 kernel. Look into the /lib/modules/fglrx directory.

That's the one - thank you.

I don't know why I didn't spot that. Maybe another Red Bull will wake me up ;-)
