> Can you see if this solves the issue on your computers? No luck here (Xubuntu 14.04), what actually did fix the issue was installing the latest stable release of lightdm-gtk-indicator from the upstream ppa. This caused a few hiccups with the Greybird theme, but at least the ghost sessions are gone without any kind of workaround.
This is a glaring red sign that neither lightdm nor upstart are the appropriate packages for this issue, but lightdm-gtk-greeter is. Anyone proficient with bzr willing to perform a bisect between 2.0.1 (ppa - working) and 1.8.5 (trusty-updates, not working)? ** Also affects: lightdm-gtk-greeter (Ubuntu) Importance: Undecided Status: New -- 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
