Bug#1051993: gdm3: System suspends after 15(!) minutes at login screen

[Michel Dänzer]

Package: gdm3
Version: 45~beta-1
Severity: normal

Dear Maintainer,


After upgrading to 45~beta-1, the system suspends after 15 minutes at
the login screen. This did not happen with older versions up to and
including 44.1-2. This is a desktop machine which is always connected to
AC.

Setting both sleep-inactive-ac-timeout & sleep-inactive-battery-timeout
(which default to 20 minutes though, not 15) to 0, and both
sleep-inactive-ac-type & sleep-inactive-battery-type to 'nothing' in
/etc/gdm3/greeter.dconf-defaults doesn't help.
