Comment # 20 on bug 1191515 from Stefan Dirsch

Thanks. Seems a Mesa update fixed the issue now. nvdia and suse-prime packages
haven't been installed again.

I would feel better if things would also work without packages 

xf86-video-nouveau
Mesa-dri-nouveau
libvdpau_nouveau

been installed though. I mean just plain intel drivers. If you could give this
a try by uninstalling these 3 packages, that would be great!
