Overview:
Whenever I disconnect or reconnect my monitor via HDMI or switch systems with
my HDMI switcher, the screen seems to be laggy and my mouse cursor won't move.
There seems to be input from the mouse as I can use the 'hidden' cursor to log
out and log back in which resolves the issue.

I can only describe the effect as being extremely laggy. In chrome I can see
that tabs change, however content won't show. I can type in the terminal but
only see some letters appearing (really slowly and random).

Steps to Reproduce:

1) Disconnect HDMI cable
2) Reconnect

Actual Results:
Slow and unusable screen

Expected Results:
Usable screen

Hardware:
NVIDIA Corporation GM206 [GeForce GTX 960]

Software:
Fedora 24
