Public bug reported:
If I restart gdm from a VT the screen starts flashing and becoming
unresponsive. If I press CTRL+C to end the process it stops flashing and
I'm again able to use the VT, but I can't start gdm again. The only
solution to have gdm back when this happens is to reboot and let gdm
start on its own.
Expected: gdm to restart and be prompted for login, or, if it fails, to
be prompted an error stating the failure reason on the VT
What happens: screen flashing like if it was continuously switching
between VTs (possibly gdm falls in an endless loop trying to start)
