Can you please elaborate on what "unable to log in" means, i.e. what happens? Does the computer freeze, or are you taken back to the login screen?
Also, can you please let us know the contents of ~/.xsession-errors and ~/.xsession-errors.old when you log in via console right after a failed attempt at a graphical login. ** Changed in: lightdm (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1408275 Title: Unable to log in with lightdm To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1408275/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
