Comment 29 for bug 747205

I'm not sure if I understand your question, but I think the answer is "no". Specifically, I don't notice a difference in behaviour that is dependent on when the monitor is plugged in. I get the same black screen result if I
(a) plug the monitor in before logging in (i.e., it goes black after I press enter to actually log in), or
(b) if I am already logged in and plug the monitor in (i.e., it goes black).

In both cases, unplugging the monitor doesn't return to normal operations - I need to reboot/relogin. Let me know if there are any other logs or debugging steps you'd like me to take.

thanks,
Jane
