Comment # 14 on bug 1188165 from Tilman Vogel

OK, I tried more in the other direction: I replaced suse-prime by
suse-prime-bbswitch and bumblebee. After gpasswd -a <me> bumblebee, I can
"optirun teams" and that works! Even though I am running with "prime-select
nvidia" anyway. 

I tried switching to "dicrete graphics" in the BIOS but then, after grub, I
only get a black screen.
