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.

The DFP-0 is the internal monitor, DFP-1 is external. nvidia-settings
shows the max resolution for the internal monitor as 640x480, which does
not give out any picture at all. Just blank screen with the backlight
on.
