I have a desktop machine with an ATI VGA/DVI AGP card driving two monitors. Everything is peachy until I connect to this machine via a remote desktop session. After a remote desktop session, I return to my desk to find one monitor completely off, and the second monitor shows a black screen and will display the cursor if I move my mouse over there.
I'm usually successful in logging in blindly, but it is getting more difficult now that my company has instituted a disclaimer screen after you login, that requires you to press OK before continuing.
I'm not sure if it is related to the problem but Windows 7 defaulted to think the monitor on the DVI card (display #1) was the primary, and the VGA (display #2) the secondary. I changed that default and set display #2 as the primary. It seems as if Windows is still outputting the primary screen to display #2 (i.e. the VGA monitor), however it isn't powering on the VGA port.
It is probably a bug given I'm running the RC of Windows 7, but just looking for ideas on workarounds.
