[LightDM] Autologin (lightdm) questions

[poma]

Essentially when not working, this part is missing in the log:
...
: Session pid=3798: Greeter sets language eu_EU.utf8
: Session pid=3798: Greeter requests session xfce
: Seat: Stopping greeter; display server will be re-used for user session
: Session pid=3798: Sending SIGTERM
: Session pid=3798: Greeter closed communication channel
: Session pid=3798: Exited with return value 0
: Seat: Session stopped
: Seat: Greeter stopped, running session
: Registering session with bus path /org/freedesktop/DisplayManager/Session0
: Session pid=3847: Running command /etc/X11/xinit/Xsession startxfce4
