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.
