Hello, here's what I did on my Xubuntu installation that seems to work: In this file: /etc/xdg/xdg-xubuntu/lightdm/
In line 27, in a default installation, it reads: show-indicators=power;~session;~language;~a11y;~power; Remove the first "power" entry, leaving only the built-in indicators: show-indicators=~session;~language;~a11y;~power; Save the file, and any subsequent lock screens and the processes they spawn should now exit properly upon screen unlock. I can't say for sure why it solves the issue on my Xubuntu, but I suspect that trying to include two power indicators might cause one or the other to prevent lightdm's indicator services instance from properly terminating. Can you see if this solves the issue on your computers? -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
