Description:

quadrapassel and gnibbles segfault if they are run as a regular user. However, no segfaults when using sudo or simply running them as root.


Additional info:

Could you attach the output of glxinfo, both run as normal user and root?
Comment by Timothy Keith (keithieopia) - Tuesday, 24 January 2012, 22:17 GMT
I think you're on to something based on the "direct rendering" line being "no" for a regular user and "yes" as root. Maybe it's a permissions issue and I need to be part of some unknown group? Also, if it helps I'm using xf86-video-intel

$ groups
wheel http video audio optical storage scanner power users vboxusers

EDIT: attached glxinfo as files instead of large copy-paste.

   glxinfo-root (12.1 KiB)

Is this still a problem?
Comment by Timothy Keith (keithieopia) - Monday, 15 October 2012, 15:34 GMT
Yes it is still segfaulting as a normal user, however it is throwing a more detailed error message about 64bit vs 32bit (I'm running 64bit):

Can you report this to the gnome games devs?
Comment by Timothy Keith (keithieopia) - Wednesday, 07 November 2012, 20:08 GMT
The problem seems to be solved now. Found a old reference in my .bashrc that when removed solved the issues:

export LIBGL_DRIVERS_PATH=/usr/lib32/xorg/modules/dri

Specifically this forum post helped:
