Thanks. >From the logs you provided: > [ 467.018796] nue-p1.nue.private systemd[1]: Got message type=method_call sender=:1.4 destination=org.freedesktop.systemd1 object=session_2d4_2escope interface=Scope member=Abandon cookie=144 reply_cookie=0 error=n/a > [ 467.019310] nue-p1.nue.private systemd[1]: session-4.scope: cgroup is empty > [ 467.019481] nue-p1.nue.private systemd[1]: session-4.scope changed running -> dead > [ 467.019650] nue-p1.nue.private systemd[1]: session-4.scope: Failed to destroy cgroup /user.slice/user-1002.slice/session-4.scope, ignoring: Device or resource busy For some reasons the session scope appears to be empty whereas it should contain at least the screen process as well as the shell used to spawn screen... Can you inspect the session status before logging out ? So after: > charly@nue-p1:~> loginctl > SESSION UID USER SEAT TTY > 4 1002 charly > 1 481 sddm seat0 > > 2 sessions listed. > charly@nue-p1:~> screen -S TstSess04 > > (terminal clears) can you run "loginctl session-status 4" and show the ouptut ?
