> 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 Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/1322275 Title: lightdm sessions started by dm-tool lock (or a session locker) never get closed Status in Light Display Manager: New Status in lightdm package in Ubuntu: Confirmed Status in lightdm-gtk-greeter package in Ubuntu: New Status in upstart package in Ubuntu: Confirmed Bug description: dm-tool lock starts a new lightdm greeter (for unlocking) and a new logind session.
