12.04 64-bit in Unity 3D with ATI graphics. (Dell Inspirion laptop) Same EXACT problem.
What happened, was I was in a session when my battery ran down to about 6%. I put it to sleep instead of shutting down. It remained asleep until the battery fully-drained. When I plugged it back in and restarted, I encountered this problem. I renamed my .Xauthority -> .Xauthority.old (taking advice from a Ubuntu Forums poster, who suggested deleting all items in the home directory that start with ".", one by one, until the problem is resolved. . . - I renamed .conf, .gnome2, .gconf, a few others. . . but by renaming BACK, isolated the problem to .Xauthority). When the ONLY configuration delta was .Xauthority (the new file, and all of my old ~/. directories were restored), I was able to log back-in, but I only saw my desktop, (and conky). All the Unity elements were missing. No launcher, no menu-bar, and the popup thing didn't respond to the "windows" key. (various things would also crash, at random: colord, and compiz). But it was definitely a different symptom than being kicked right back to the login prompt as before. I tried to chown .Xauthority to my user, but that did not fix 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/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
