After connecting from my home via remote desktop, both my screens are black when I arrive at work. The only thing I can see is a mouse pointer on one of the screens. I then seem to have only two choices: rebooting or working from a remote desktop connection, which works fine.
It did happen every time I tried last week.
However, I did the same from my laptop in a meeting room today, and I didn’t have any problem.
Solution:
I have had a similar issue. While not a fix this is the work around we found to avoid restarting: While one of you screens is black and not showing the mouse the log-in screen is actually there.
Use the keyboard to log into your account (we press Esc a few times, then ctrl+alt+delete, then enter password and hit enter) you will log in and the monitor that wasn’t showing the mouse cursor will come back to life.
Again, just a work around I’m afraid but it saves a reboot or two.
