Let's see, I cannot log in in Lubuntu 12.04. On the shell I get when typing startx:
_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeA11C0TSServerListeners: server already running
Fatal server error:
Cannot establich any listening sockets - Make sure an X server isn't already running
...
Please also check the log file at "/var/log/Xorg.0.log" for additional information.

Before I had only read-right on the file-system with sudo autoremove I got my write-rights back. I removed the .Xauthority* files in /home/username. Still cannot login back
