I can start lightdm manually (systemctl start lightdm). But 'systemctl status lightdm' still shows some issues: Loaded: loaded (/lib/systemd/system/lightdm.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2017-09-21 20:02:13 CEST; 1min 29s ago Docs: man:lightdm(1) Main PID: 17728 (lightdm) Tasks: 6 (limit: 4915) CGroup: /system.slice/lightdm.service ├─17728 /usr/sbin/lightdm └─17734 /usr/bin/X :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch Sep 21 20:02:13 cheetahnew systemd[1]: Starting Light Display Manager...

I have this issue for some days on all machines, which I tested.
Could this be the same issue as https://bugs.gentoo.org/645648 ? If so, manually changing the symlink worked fine for me
Is this still a problem with 1.32.0?
