I also experienced this bug after upgrading to 12.04 from 10.04. After chaning settings using Ubuntu Tweak, I could not login using LightDM at all. Switched back to GDM and was able to login & debug the issue.
Yes, I had DISALBED the login sound using Ubuntu Tweak. After re- enabling the login sound, I switched back to LightDM and was able to login perfectly. This appears to have something to do with the login sound and/or timing upon login. AGAIN, re-enabling the login sound appears to correct this issue. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/986967 Title: unable to log in - hangs on 'logging in' msg Status in Light Display Manager: New Status in “lightdm” package in Ubuntu: In Progress Status in “lightdm” source package in Precise: In Progress Bug description: On my laptop I upgraded from 11.10 to 12.04, 3 or 4 weeks ago. Recently I had trouble logging in - I'd type in my password but it would hang on the 'logging in...' message you get after pressing enter. After rebooting a few times I was able to log in. Now, rebooting isn't helping, I'm unable to log in at all. I stay at the 'logging in...' message until I shut down.
