It took me a couple of hours to figure out why root could run glxgears
and my normal login could not - xorg.conf was lacking the Section DRI
settings that give the access mode to the DRI memory space and/or groups
who have rights to DRI:
Section "DRI"
Mode 0660
Group video
EndSection
(making sure, of course, I am a member of group "video"). The
alternative is to set Mode 0666 so anyone can use DRI.
I know that's covered in FAQs all over the world, but I figure it makes
sense for it to be included with the other xorg.conf instructions.
