    Login loops back to login screen (12.10)

    hello there, I have a problem.

    when I login, it loops back to my login screen. however, when I enter the wrong password, it tells me it's wrong.

    I am aware that other people have had this problem elsewhere:http://askubuntu.com/questions/19711...grade-to-12-10, but they posted in the wrong place.

    HELP!

    I am having the same problem. Is it being discussed/addressed elsewhere?

    Press Ctrl + Alt + F1 to get inside a tty, log in, and type this command:
    Code:
    sudo chown username:username .Xauthority
    replace username with your user name.

    Have you been using the 'sudo' command with graphical applications lately? This is incorrect and usually the reason why this happens...
    One should only use 'gksudo' with such apps.

    Here is more info on that: LINK
    Graphical sudo

    You should never use normal sudo to start graphical applications as Root. You should use gksudo (kdesudo on Kubuntu) to run such programs. gksudo sets HOME=~root, and copies .Xauthority to a tmp directory. This prevents files in your home directory becoming owned by Root. (AFAICT, this is all that's special about the environment of the started process with gksudo vs. sudo).
    Examples:
    Code:
    gksudo gedit /etc/fstab
    or
    Code:
    kdesudo kate /etc/X11/xorg.conf
    • To run the graphical configuration utilities, simply launch the application via the Administration menu.
    • gksudo and kdesudo simply link to the commands gksu and kdesu
    How do you sudo?
