Comment # 6 on bug 957917 from Stefan Dirsch

This looks like an Optinmus system (intel+nvidia GPU). Either 

1) try to disable nouveau kernel module completely, i.e. add it to blacklist 

--> /etc/modprobe.d/50-blacklist.conf

blacklist nouveau

Regenerate initrd via 'mkinitrd' command. Reboot. nouveau kernel module
should no longer be loaded (verify via 'lsmod').

Or 2) switch to intel GPU alone within your firmaware setup(if available).
Or 3) switch to NVIDIA GPU alone within your fimrware setup (if available).
      Then install NVIDIA driver according to our WIKI (the easy way):
      --> https://en.opensuse.org/SDB:NVIDIA_drivers

Does that help?
