Bug Description
When the mouse cursor leaves one of the screens, there is either :
- no problem
- the screen becomes black just below the position of the cursor and instantly comes back to normal.
- the screen becomes entirely black with some random colored pixels flickering on the far left of the screen. I have to move the cursor to the black screen, otherwise it stays black.
It happens on Ubuntu Gnome 16.04 Beta and Ubuntu Mate 16.04 Beta.
I have tested with other distributions (Debian Jessie and Fedora) and everything is fine.
Hardware : Intel Ironlake (Thinkpad X201) with an external monitor plugged in.

groucho, thank you for reporting this and helping make Ubuntu better.
To clarify, did this problem not occur in a release prior to 16.04?
