Bug#637142: GDM3 - very slow start up

[lesh88]

Package: gdm3
Version: 3.28.2-4
Followup-For: Bug #637142

Dear Maintainer,

This bug is the same on my PC, the login is very slow and often it doesn't load
the desktop on version 3.28.2-4.
To solve it, I have to click random and move the mouse random. When I do that
the desktop appears.
I expect that the desktop appear when i enter the password and i press enter.

Regards
