 |
|
When I start glxgears, I get the error in the title. I am using a Radeon Mobility X1400 card on a ThinkPad T60 with the ATI drivers. Undoubtedly I have configured something wrong, any guesses? 
| Code: | schiotz@newdemokrit ~ $ glxgears
libGL error: failed to open DRM: Operation not permitted
libGL error: reverting to (slow) indirect rendering
2188 frames in 5.2 seconds = 418.432 FPS
2160 frames in 5.3 seconds = 411.195 FPS
schiotz@newdemokrit ~ $ eselect opengl list
Available OpenGL implementations:
[1] ati *
[2] xorg-x11

If you try running glxgears as root, do you get that error? If not, try adding yourself to the video group `gpasswd -a schiotz video` to see if that fixes it.

To get some more verbose error messages, try this:
| Code: |
$ LIBGL_DEBUG=verbose glxinfo
|
And tell us what that says.

Thanks for the replies! I get no error as root. I ran the suggested debugging command as myself and as root, and compared the results. This indicates that the problem is permissions on /dev/dri/card0:
| Code: | schiotz@newdemokrit ~ $ LIBGL_DEBUG=verbose glxinfo
name of display: :0.0
libGL: XF86DRIGetClientDriverName: 8.32.5 fglrx (screen 0)

drmOpenDevice: open result is -1, (Permission denied)
drmOpenDevice: open result is -1, (Permission denied)
drmOpenDevice: Open failed
drmOpenByBusid: drmOpenMinor returns -13
....
|
Note that alll the first error until the drmOpenByBusid line also occur for root, so it is apparently not a real problem
| Code: | ls -l /dev/dri/card0
crw-rw---- 1 root root 226, 0 2007-02-14 11:04 /dev/dri/card0
|
Should the group be video? If so, what causes this problem?
Best regards

Do you have | Code: | Section "dri"
Mode 0666
EndSection |
In your xorg.conf?

Actually, I believe the problem lies in this line:
| Code: | | libGL error: dlopen /usr/lib/dri/fglrx_dri.so failed (/usr/lib/dri/fglrx_dri.so: cannot open shared object file: No such file or directory) |
If it can't find the driver file, obviously it can't load it :p. I had the a very similar problem, and resolved it by doing | Code: | | # find / | grep -i fglrx_dri |
and then symlinking it to /usr/lib/xorg/modules/fglrx_dri.so.
Hope this helps!
Also, see this thread: https://forums.gentoo.org/viewtopic-t-520835.html specifically page 2.
