Bug Description
The system is an Intel NUC D34010WYK with an i3 Hasell processor.
Monitor 1 is connected via micro HDMI
Monitor 2 is connected via mini DisplayPort
At boot BIOS, Grub, systemd, all get mirrored on both screens as expected.
However, once the login prompt hits Monitor 2 (DisplayPort) goes blank. It flickers periodically though.
When it does flicker on I can see the desktop, any windows that got moved to that monitor and the clock is up to date.
The two monitors are exactly the same model, Samsung SyncMaster 204B.
I have tried swapping monitors and the issue seems to persist on the mini DisplayPort connection only.
