Public bug reported: The built-in screen is blank with nvidia drivers enabled on Macbook Pro 5,5 13.3" model. The screen does work with the nouveau drivers, though they do not work on native resolution. Nvidia drivers do work with external monitor when configured with nvidia-xconfig --twinview command in cli. The problem seems to be caused by incorrectly read EDID information from the monitor as seen in xorg.0.log (full log attached):
(WW) Mar 29 17:49:50 NVIDIA(GPU-0): The EDID read for display device DFP-0 is invalid: the (WW) Mar 29 17:49:50 NVIDIA(GPU-0): checksum for EDID version 1 is invalid.

Just blank screen with the backlight on.
