Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

When I go to the home user and enter my password, I see a black screen, then flashes and it back to the login screen and asks me to reinsert my password in an infinite loop of logins.

I entered in TTY pressing Ctrl+Alt+F2 and login from there without problems. But when I try to enter with startx or xinit I get a server error (1)

We try to reconfigure xinit, try and purge, remove, clean, re-install xinit but I still have the receipt problem.

I can only enter in the guest session, in my personal session passes this problem

I have Ubuntu 12.10 and unity for default and my graphic card is a GeForce 6200 (not problem with card, windows not have problem)

Ubuntu says that your password is wrong? – Lucio Feb 17 '13 at 20:03
Could you use the guest account, and tell me if you have a file named ".Xauthority" on your user home folder? – Fábio Antunes Feb 17 '13 at 20:43
PS: If you can't see hidden files (.dotFile) use Ctrl+H to show them. – Fábio Antunes Feb 17 '13 at 20:54
