A quick update of my experience -

When booting with an external monitor connected to my laptop, I get to the gdm login and successfully enter my password. Once the login event starts occuring, the laptop monitor goes black and the external monitor randomly and quickly flashes colors. I can switch to a terminal; switching back with ctrl+alt+f7 shows BOTH screens as black, but I will now seen a mouse cursor.

As a workaround I boot without the montor attached, go to System Properties > Multiple Screens, turn OFF the laptop monitor, plug in the external monitor.. and the display correctly comes up on the external. Enabling the laptop monitor again will reproduce the behavior described above.

I will be happy to do any diagnostic testing you need when I have access to my machine tonight around 5pm EST. Please advise as to any logs etc which may be of assistance. Thanks.
