Public bug reported: This concerns system-config-printer 1.5.12-0ubuntu1 in Ubuntu focal.
I log into the Xfce desktop, and then logout. The screen returns to the LightDM login screen. A few minutes later, "loginctl list-sessions" shows the following: SESSION UID USER SEAT TTY 9 0 root c2 1000 skunk seat0 c3 116 lightdm seat0 3 sessions listed. Output from "loginctl session-status c2": c2 - skunk (1000) Since: Fri 2020-05-08 03:09:05 EDT; 9min ago Leader: 2530 Seat: seat0; vc7 Display: :0 Service: lightdm; type x11; class user Desktop: xubuntu State: closing Unit: session-c2.scope └─2856 /usr/bin/python3 /usr/share/system-config-printer/applet.py This process sticks around forever until I kill it, or its parent "systemd --user" process. Only then does the session disappear from list-sessions. When I run "session-status" while I'm logged in, I see a list of nearly 30 desktop-related processes. All of them except this one go away on logout. This one should too. ** Affects: system-config-printer (Ubuntu) Importance: Undecided Status: New ** Tags: focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877528 Title: Applet does not terminate at end of X desktop session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/1877528/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
