Control: reassign -1 xscreensaver I don't see a systemd problem here, so re-assigning to xscreensaver.

Package: systemd Version: 247.2-4 Severity: serious Hi, I am reporting this with high severity because it might affect system security. For details of this issue, see 978589. There are different symptoms to see but the originating cause is apparently the same: - xscreensaver user service is enabled as documented in its README - lightdm starts the service in its internal user session (owned by "lightdm" user) - lightdm stops its session when the login happens. However, xscreensaver process is NOT terminated for unknown reason. - having this xscreensaver hanging around disturbs the startup of another xscreensaver process in the new user session - after ~15s the old xscreensaver process (from lightdm) is finally dead, apparently a SIGTERM is emited only then! Visible symptoms: In the meantime, someone might lock the system (by xscreensaver-command) and go away, assuming that xscreensaver is locked. And then it suddenly dies. Same things happens if xscreensaver is invoked from .xsession or similar contents instead of user service.
