Bug#724731: [gdm3] gdm does not start properly, cannot login via gdm

Mon Sep 30 20:04:29 UTC 2013

I have also tested GDM 3.8. Unfortunately, all I see is a blank screen.
I heard that Gnome 3.6 and higher requires systemd to work. So I
installed the sytsemd packages (without its recommended packages) but
the screen remains blank. Then I figured out that I need to install the
"libpam-systemd" package too. It works!

It looks like GDM3 needs a hard dependency (e.g. no "recommends") to
systemd and libpam-systemd.
