Bug#652467: gdm3: doesn't show X after startup, but after changing in TTY it does

[Benjamin Sack]

Package: gdm3
Version: 3.0.4-4
Severity: normal

Dear Maintainer,

gdm3 shows some weird behaviour. I use autologin through the configuration of
the /etc/gdm3/daemon.conf file. Worked well till yesterday. After updating some
packages, gdm starts but X won't show up. Funnily enough it does after
switchting to TTY with ALT+F1-6 and then switching back to X with ALT+F8. 
Doing that brings me to my Desktop, fully logged in.
