lightdm (1.11.4-0ubuntu1) utopic; urgency=medium

* New upstream release:
- Do timed autologin each time you are returned to the greeter
- Fix tests failing with Qt 5.3 due to it checking getuid/geteuid

- dm-tool: Warn if trying to switch to user without username
* debian/lightdm.service:
- Don't test for specific installation path
