OpenGL only works correctly as root

guitarfella · 11-19-2008, 09:41 AM

I'm actually trying to get beryl to run on Slackware 12.0 over XFCE. Beryl runs fine when your logged in as root (i was just testing) and when running as my user account, it doesn't behave as expected. I figured it was some sort of device permission thing. here is some info:

Code:

ls -l /dev/nvidia*

crw-rw-rw- 1 root root 195,   0 2008-11-20 01:16 nvidia0
crw-rw-rw- 1 root root 195, 255 2008-11-20 01:16 nvidiactl

can anyone help? thank you

First try adding the other users to the 'video' group (you can manually edit /etc/group). If that still doesn't work, try changing the group ownership of the devices to 'video'. If that works, you may need to edit the udev rules to ensure that the appropriate video devices have group membership in 'video'.

Beryl is old, and has merged with compiz (into compiz-fusion) more than 1 year ago. I'd recommend to try compiz-fusion instead of beryl.

Access right are correct, I have exactly same rights on those files. Try newer compiz-fusion instead of beryl.

If it works without compiz, then you probably have correct permissions. And the appropriate X conf entry. If not you might be missing the below from your xorg.conf.

Section "DRI"
Group "video"
Mode 0666
EndSection

Along with the user in the video group. And a driver that supports acceleration. As I wonder if ATI's drivers support 3D acceleration with compiz yet?
