unity-greeter has code to kill upstart, but for some reason this isn't being executed. My best guess is that unity-greeter often (if not always) dies before it exits the GTK main loop. Does it receive a second SIGTERM, or a SIGPIPE? (When lightdm says "Stopping display server, no sessions require it", I would think.) This should be testable.
Amending my earlier comment #7, I do see "Got a SIGTERM" some of the time, but I hardly ever see "Cleaning up" (when unlocking; new logins are another story). Indeed upstart is not to blame: it shuts itself off cleanly when signalled; the problem seems to be that unity-greeter doesn't send out that signal as it is supposed to. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1322275 Title: lightdm sessions started by dm-tool lock (or a session locker) never get closed To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1322275/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
