[Bug 1559308] Re: Plugging HDMI screen in causes system hang
Christian: your cpu is broadwell, not skylake like for others on this
bug. Broadwell uses the stock i915 driver from 4.4, so file a new bug.

Title:
Plugging HDMI screen in causes system hang
Status in linux package in Ubuntu:
Fix Committed
Bug description:
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.
