[BUG] Displays won't reconnect after being turned off.

[jorge-menjivar]

I am experiencing the following issue with dual monitors and nvidia graphics.

When trying the new cosmic idle feature that turns off the displays after some amount of time, both of my monitors will turn off as expected. However, when I move the mouse to turn them back on, sometimes only the main display turns back on. Manually turning the displays on/off after this point will cause both displays to not connect at all.

I am not sure if the system crashed after that point or not. It might be related to #906 if that is the case.
