Bug#893964: gdm3: System goes into suspend mode unless a user is logged in on the console.

[Russel Winder]

Package: gdm3
Version: 3.28.0-1
Severity: normal

Dear Maintainer,

With the update to 3.28 a newly rebooted machine that starts GDM will suspend after about 15 mins unless a
user logs in to the console.  This means it is no longer possible to remotely reboot computers that run GDM
and then login over SSH, since SSH is not recognised as being used. This is but one workflow that is now
impossible as there appears to be no way of switching the GDM suspend behaviour off.

The Fedora people are having a debate about this at https://bugzilla.redhat.com/show_bug.cgi?id=1558485
