gdm has multi seat support btw: it will spawn X servers on all seats
capable of graphics. if you unplug all graphics cards than this simply
means that your number of graphics-capable seats went from > 0 to
0. That's all. And if you plug in a graphics card then, then it goes
from 0 to 1 again and you get a fresh new login prompt on it.
