Public bug reported:
I have a monitor connected to my macbook air 4,2 through a dvi to mini-
dvi adapter plugged into the thunderbolt port. If I have the adapter
connected to the mac when I start up, everything works fine. However,
when I remove or connect the dvi to mini-dvi adapter while the mac is
booted into Ubuntu, then the screen goes black.
