Public bug reported:
This is a regression, at least trusty (and prior) worked fine on this
hardware.
Booting the Xenial installer image off USB also worked fine.
The system boots fine, however the monitor is in DPMS power-off and does
not ever turn back on. Switching VTs doesn't help, I have found no way
to get it switch on.
Removing '$vt_handoff' from grub resolves the problem and the system
seems to work fine.
