can't guarantee that there is another GPU to display things on.
Yes you can.
Wait, what? No, you can't.
1) Not everyone has multiple monitors plugged into multiple GPU's.
2) The system ships with a dGPU and supports an xGPU. If you remove the
dGPU from the chassis, all you have is the xGPU. If you unplug xGPU,
there's nothing left..
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.

Lennart,
The kernel bits and discussion around hot unplug aside, can you please
add support to systemd to map the scan codes? For the other scenarios
such as the cable being connected and the disconnect button being
pressed userspace will need to provide a notification to the user what
to do next. I've added the details (and a proposed patch) to bug
90689. If these are also controversial, I'd like to know what else you
have in mind.
Thanks,
