A colleague of mine was also affected by this bug upgrading to 12.04. Just had to change the owner of the .Xauthority file: chown myuser:myuser /home/myuser/.Xauthority (.Xauthority was previously owned by root).
But from the user point of view, this bug is really hard to understand. When he try to login, the screen just get back to the login screen after few seconds. There is no error message, neither no log about what is the issue anywhere. It would be good to at least have an error message giving a clue about what is the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/871667 Title: .Xauthority sometimes owned by root, which blocks login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/871667/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
