Hello Christopher,
I am not sure whether this is a xorg or kernel issue. xorg is not installed.

Complete new reinstall on the same server and I can confirm that the
main VGA connector works. If I switch to the front VGA the screen is
black. On trusty I see at least errors in dmesg (see mentioned bug in
#4) but nothing on xenial.

expect the login prompt, no output is sent to the monitor (black).
I documented this on the following video:
