Bug#681310: gdm3 sometimes starts greater with ugly graphics (no wallpaper and poor gtk theme for the login window)

[Laurento Frittella]

Package: gdm3
Version: 3.4.1-2
Severity: normal

Dear Maintainer,
sometimes on the first start (just after the boot process) gdm3 starts in an ugly mode without graphic stuff: a black screen instead of the nice debian background and without the usual gtk theme for the login window.
If I manually restart the service all work as expected.

I suspect a problem with the service start order during boot... here is my (cleaned) bootlog file:
 INIT: Entering runlevel: 2
 Using makefile-style concurrent boot in runlevel 2.

Workaround:
 * switch to the tty1
 * /etc/init.d/gdm3 restart

Cheers,
Laurento
