Hi,

I just installed Slackware 11 with 2.4.33.3 kernel.

Now i'm triyng to get my Ati Radeon 9600 to work with 3D support, but i can't seem to get it working. Well, i can get it to work but only as root, not as a normal user.

When i issue the fglrxinfo as a normal user i get:

libGL error: failed to open DRM: 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 6.4.1)

But when i do the same as root, all works fine !!!

This what i did:
- Installed the full slackware 11 with 2.4.33.3 kernel
- Configured Xorg with xorgconfig
- created a regular user with the adduser command
- Edited my fstab and added: tmpfs /dev/shm /tmpfs defaults 0 0
- issued the comand: mount /dev/shm
- Confirmed with mount | grep shm
- Went to the ATI web site and downloaded the latest drivers
- Chmod 700 the file and run the ATI driver installer
- I then run "aticonfig --initial --input=/etx/X11/xorg.config

As root all seems to work fine, and i can put my favorite screen saver working (the one where there's an ant running on my screen with a flash light ), but as a normal user it simply doesn't work.

Could this be a permissions problem ??? Or is this something more serious ???

Regards

Look in your Xorg.conf file. At the end should be a small section for DRI with a line that reads MODE "0666". Also make sure your user(s) belong to the video group.

Hi,

It seems i don't have that line anywhere on xorg.conf !!!

Could you tell me where to add it ???

Regards

Hi,

Did a search and found a similar problem.

Added this to end of my xorg.conf:

Section "DRI"
Mode 0666
EndSection

Thanks for your help

Regards
