I issued bug #877622, which was marked as a duplicate of this one. I've now worked around the problem by issuing the following command in the terminal:
sudo chown -R username:username /home/username This allowed me to log in graphically to my user account for the first time after I did a clean install over Natty. Recreating the other user accounts in the GUI perfectly reconnected them with their home directories and I haven't experienced any problems so far. I'm going to wait a couple of weeks before installing Oneiric to my other two machines, however. -- 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
