I can’t shut down nor reboot without console

Title says all. When I choose shut down or hibernate if my computer has been on a while, it just goes to the log-in screen. If I choose the shut down option there, it does nothing.

It only happens if I leave it on for a while. I do not have auto login enabled. I am running 11.10 ( with all the latest updates). I can shut down using the terminal.

Used to have the same problem, run this on a terminal:

sudo poweroff

The problem get fixed by itself after several times i had to do that.

Also check if theres a .Xauthority file in your home folder owned by root.
Log in a text console (Alt+Ctrl+F1) at the login screen, and then run

sudo rm ~/.Xauthority

Hope it helps. (:

Thanks! I will see if this works. Also, is it safe to do the terminal command even if you do not see that file, and do you mean do the sudo power off command when I have the problem, or run it several times in a row. –  Rocket101 Jan 8 '12 at 23:17
    
1. Yes it is Safe, if the file doesn't exists, it will show you a message like "the file doesn't exist" or something like that. 2. I mean do the sudo poweroff command when you have the problem only once (It will be enough) –  iLQ Jan 10 '12 at 2:18
