libGL permissions error

Hey all, I was testing out graphics capabilities, and so I downloaded Tuxracer to try it out. When I run it, the display is ridiculously slow. It gives the error,

libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering

Slow indeed! So, to see if it is really a permissions problem, I su and play Tuxracer as root, and it plays at full speed.

How can I give my standard user permissions to open DRM? Is there a group I need to add myself to, or..?

Thanks!

Re: libGL permissions error

/etc/X11/XF86Config / xorg.conf should have this:

Section "DRI"
    Group      "video"
    Mode       0666
EndSection

and your user should be in the "video" group


The impossible missions are the only ones which succeed.
