I've been experiencing this error for a while too, and reading the comments above I see that ssh -X was a component of the issue for a lot of people. I frequently log into this computer via ssh -X. I hadn't thought to consider that as a potential part of the issue, before. Looking at a backup .Xauthority I made when I was clearing it out to log in again, I see that there are a lot of magic cookies inside. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1036830 Title: Can't log in unless remove .Xauthority or use gdm To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1036830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
