I think the above line is logged on systems that have both intel
and nvidia gpus.  The system runs on the intel, so the nvidia can only
be used with optirun.  Unlikely to be the problem.  If you are using
KDE, it seems a little iffy on some intel hardware right now, maybe try
software rendering instead of opengl?
