I have the same problem using GDM. So, I think it's not related to lightdm. In .xsession-errors I read dbus terminated with status 2.
What can I do to track down the problem and get my system working again? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283826 Title: lightdm hangs after updates To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1283826/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
