Bug#672980: gdm3: relogin after logout not possible - displays go into standby (very large 2x 24")

[Arnaud Installe]

Package: gdm3
Version: 3.4.1-9
Followup-For: Bug #672980

Not sure if this is the same bug, but after boot, gdm3 works perfectly fine, I
can login and start a session. However, when I close the session, first I get a
spinning cursor for a while; then I get the message "Oh no, something has gone
wrong..." and I can't login any more, until I reboot. (IIRC restarting the gdm3
service didn't help.)
