    In the session before it happened, did you install graphics drivers, any other software or have a software update ?

    Are you getting any message telling you the password is incorrect ?

    It sounds like X windows may be crashing.

    Kind regards
    it started when my desktop hanged. when i forced to shutdown, and try to login, that is the time that i cant log in but i input the correct password

    I have an idea. If you have any files that you need to retrieve, I recommend that you boot up via a live cd and retrieve the files if possible, then do a reinstall, I've heard that can work, it would show the hard drive as a mounted disk.

    EDIT regarding your newest post: If you can login via terminal successfully (implying that's possible), then it may be a GUI issue.

    Hi

    Login to a console (ctrl + atl + F1) and type

    Code:
    sudo apt-get install pastebinit
    This will install paste bin and allow use to see your logs.

    Then type

    Code:
    pastebinit /var/log/Xorg.0.log
    Post the URL created back here and we can see your X log file.

    Kind regards

    walter3 ; Hi ! Welcome to the forum .

    I did not notice anything alarming in your output.

    Let's back up to square one.
    Can you log in from the text console (ctl+alt+f1 at the GUI login) ?
    show the out put of terminal commands:
    Code:
    ls -al .ICEauthority
    ls -al .Xauthority
    good as any place to start

    Re: i can't login in ubuntu 12.04 LTS.

    Hi Bashing-om! This is my first hard issue with Ubuntu since 2010...

    I can login to TTY1. I can also login from the GUI to the Guest User, and I have created a new user, which also works in the GUI.

    I have already tried to reassign the owner of .ICE and .X

    This is what I got:

    -rwxrwxr-x 1 walter walter 27984 sep 15 14:34 .ICEauthority
    -rw------- 1 walter walter 0 sep 23 21:50 .Xauthority

    And again, thanks for your help (and sorry for using this old thread)

    Re: i can't login in ubuntu 12.04 LTS.

    walter3; Welp;

    That do narrow things down to a config file, huh .
    What version and distribution are you running ?
    Have you tried resetting the desk top back to defaults ?

    And let's see what is:
    Code:
    sudo ls -la /var/lib/lightdm
    ownerships - "assuming" that is your DE

    Lemme check ! Why is your .Xauthority file size "0" ?

    Edit: File size "0" not as expected -> no cookies to authorize access. Do:
    Code:
    xauth list
    to confirm.

    When you get caught up to here, and ready to proceed, I may have an easy solution.

    I be look'n

    Description: Ubuntu 12.04.3 LTS
    Release: 12.04
    Codename: precise

    I try to reset trough unity --reset from tty1, but it failed. Errors from D-Bus daemon (no protocol) and X11 initialization. Should I run this from the other session I've created?
