This should never happen. I'm curious as to how you even got this 
message :)

Do you have permissions to /dev/drm/* and /dev/dri/*? (video group)
Do you have the latest libdrm and mesa installed?

Try running with MESA_DEBUG=1 LIBGL_DEBUG=verbose to see more debug 
info,
but you're probably already getting 'MESA-LOADER: failed to retrieve 
device information', right?
