The pam module of systemd has a parameter kill-session that will kill all remaining process when a session ended. However, if this option is enabled, kde cannot shutdown or reboot the computer from a user session (can still do that in kdm). Reproducible: Always Steps to Reproduce: 1. use systemd 2. add kill-session=1 to systemd line of pam.d/kde 3. login and poweroff/reboot from menu Actual Results: fall back to kdm login screen Expected Results: poweroff/reboot
The kill-session parameter is renamed and then removed.
