Hi
Since [31c946e85ce6b48ce0f25e3cdca8362e4fe8b300] drm: If available use
atomic state in getcrtc ioctl, X doesn't start correctly on my
Sandybridge machine
I've tried reverting this commit and my X session still starts up blank
It only works again when I pass i915.nuclear_pageflip=0 - I realise
this is pretty new stuff but I thought I'd let you know I've been
testing it and it's stopped working on Sandybridge
Cheers
Mike

nuclear_pageflip=0 is the default. If you use this then you get to keep
all the pieces since we atm now that it doesn't fully work.
