Bug Description

Recently I have come to use Whonix 15.0.0.7.1 as guest OS running in a VM under KVM, while the host OS I am running is Ubuntu 18.04.3. Problem is the slow shutdown of Whonix which most of times takes about 2 minutes. There is a problem report regarding this issue on Whonix which testifies I am not the only user affected by this problem.

Still other people seem not affected (a regular shutdown should take about 3 seconds).

One of Whonix maintainers Patrick asked for log files. Part of the systemd log:

Jan 24 11:13:38 host systemd[1]: session-1.scope: Stopping timed out. Killing.
Jan 24 11:13:38 host systemd[1]: session-1.scope: Killing process 1956 (lightdm) with signal SIGKILL.
Jan 24 11:13:38 host systemd[1]: session-1.scope: Failed with result ‘timeout’.
Jan 24 11:13:38 host systemd[1]: Stopped Session 1 of user user.

This provoked Patrick to ask for the lightdm logs. I sent those as well, which did not reveal anything out of the ordinary. Still Patrick thought I should contact the upstream maintainer of the lightdm package. Version lightdm: 1.26.0-4.
