--- Comment #2 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
Can you explain what steps you take in order to make this happen? It seems like
vgaswitcheroo turns off the nvidia card, and then Xorg sends it an ioctl (which
I would have assumed should fail) which breaks since the card is off.

still a problem with newer kernels (3.17, 3.18)? there were really many fixes
in between that could fix this...
