[Bug 946311]


Hi, tested yesterdays drm-intel-nightly with hope this patch will fix

    drm/i915/dp: workaround BIOS eDP bpp clamping issue

suddenly it is not.
Right now i found one more way to bring eDP up. After start i can open gnome-control-center, display setting and press save. No changes needed. It will reenable eDP. Output of xrnadr --verbose, before and after this action, differs only here:
< 	CRTCs:      1 0 2
> 	CRTCs:      0 1 2

will it help?

Bug description:
  This is regression after some recent (2-3 weeks) xorg? update.

  I also tested newest kernel v3.3.0-rc6 with no changes, so we can
  exclude kernel.

  This ultrabook is intensively used. So if you need some testing, i can
  do it only on weekends.
