Bug#744152: gdm3 doesn't display anything at all anymore

[Gerfried Fuchs]

Package: gdm3
Version: 3.8.4-6
Severity: grave
Justification: renders package unusable


     Hi!

 Since the upgrade last weekend I am unable to get any login possibility
to my X anymore with gdm3.  The screen only keeps black.  I can
ctrl-alt-f1 to the text console, so it doesn't freeze up completely.  I
can startx /usr/bin/metacity so it's not the xorg configuration.  When I
try to startx gnome-session I get that splash screen that something went
wrong and just wants to log me out (probably I should file that as a
sperate bugreport?).

 Please let me know what you need to debug this further, it's pretty
tiring to have to do the startx dance and send it a terminal to do
anything graphical. :/

 Thanks for looking into the issue!
Rhonda
