Bug#940614: gdm3: GDM doesn't start (I see flickering on the console a few times until it decides it has failed)

[philippe batailler]

Package: gdm3
Version: 3.34.0-2
Followup-For: Bug #940614

Dear Maintainer,



   * What led up to the situation?

An upgrade from testing

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

apt upgrade

   * What was the outcome of this action?

a black screen on reboot.

I tried lightdm : I only get a gnome terminal. no desktop. and i can not close
the session.
I can launch emacs firefox or reportbug...

Regards,
