> 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)?
