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!

/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.

Works perfectly, thanks.
