[Launchpad Bug Tracker <1559308@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
using 4.4.0-13-generic and the Nouveau drivers.

If I plug in an external HDMI monitor (FHD) either into either HDMI port
(there's one on the machine and there's one available via a usb 3.1
extra adaptor) then the whole system hangs, completely unresponsive and
needing a hard reboot. Before hanging the 2nd display gets an image as
expected, but the laptop's screen flashes randomly, sometimes you see
weird artifacts. Then the hang comes.
