I will be back from vacation on Jan 19th and then test report on #28 more

Wladimir, can you test the kernel in comment #28 since you are the
original bug reporter?
Thanks for the pointer to commit d472fcc, William. That commit is in
mainline as of v3.19-rc2. It was also cc'd to stable, so it should
also make it's way into all the stable kernels.

X server disables acceleartion or turns off output (makes screen
black)
Thanks for testing. We can perform a Reverse bisect to identify the
commit that fixes this in 3.19. First, can you also test the latest
3.18 upstream kernel to see if it already has the fix? It can be
downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18.2-vivid/
