Re-opening this because the original problem still exists (fully updated
Natty beta as of 6 April).  If I boot with external monitor attached,
the screen of laptop and monitor turn black as soon as I log in.  If I
boot without external monitor, I can log in and the desktop appears as
expected.  If I plug an external monitor or projector in after the
desktop is running, then it either turns black or a blinking solid dark
red colour.
