--- Comment #26 from Peter Wu <peter at lekensteyn.nl> ---
Fixed the black screen issue (nouveau) and crash (modesetting) in
xf86-video-intel 2.99.917-895-gcb6bff95.

Sometimes there is still a crash on Xorg exit when a external screen is
attached, but at least it does not happen while in use (hopefully!). I can live
with that issue, but for completeness the trace can be found below.

Thread 1 "Xorg.bin" received signal SIGSEGV, Segmentation fault.
