maybe xorg server?: gnome is not starting without a screen connected?

Sat Mar 11 22:20:08 UTC 2017

Hi Eric,

This is basically just a normal desktop pc.
it is headless because it has no screen.
a keyboard is connected though.

on the arch wiki i read that this is a problem with auto configuring the 
screen.
the server can't find a screen on all graphics adapters so it seems to hang.
but yeah we will see.
Maybe someone else can chime in here.

but i might call a gnome mailing list.
maybe someone there has an idea what to do.

greetings,
Simon
