Silly me, I had overlooked the fact that we aren't using the same greeter. I've got [SeatDefaults]greeter-session=unity-greeter in /etc/lightdm/lightdm.conf. So of course your solution didn't work for me. (I need to give users a choice of desktop sessions, and found unity- greeter to be better at remembering a user's last session.)
You may have found a valid workaround for GTK greeter users; unfortunately I cannot switch to it. -- 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 upstart package in Ubuntu: Confirmed Bug description: dm-tool lock starts a new lightdm greeter (for unlocking) and a new logind session.
