    Login Loop

    I have used Mythbuntu for at least 5 years now with very few problems. I am running 12.04 and everything was running very slow so I rebooted the computer (runs both front and back end). I came to the general login screen and entered my password and after a few seconds the screen turned blank, then a few seconds of that, then back to the login screen. I can login as guest, but I have no permissions to do anything (like start the front end). I don't know all that much about ubuntu, so please reply as though I know very little. Thank you in advance for your help!

    Re: Login Loop

    I tried the solution listed in the second thread. When I tried to login as user what do I type. On my main login screen it says JC-Myth under the icon of the computer. The user is JC (my initials). I tried both of those as the user and it told me the password was incorrect. I know the password was correct.

    Re: Login Loop

    Does the partition have enough available space on it? Check with -
    Code:
    df -h
    You may try logging into one of the virtual consoles with Ctrl+Alt+F1 to run above command. Alternatively, you may try the recovery mode or a live session.

    Re: Login Loop

    Alright I may have something useful to someone who knows what they are doing. I have to type this in as I am on a laptop and the system is on a desktop and I'm not sure how to transfer this any other way. I scrolled down and tried the next solution on the second thread. I typed sudo apt-get install --reinstall xorg then it asked for my password and accepted it. the following is what appeared: (I think this is correct, but I cannot see the first character, something with the display on the TV, it works fine when I am in Ubuntu I used my best guess or put a question mark)

    Re: Login Loop

    Are you comfortable with terminal??

    If so, have you tried using the terminal in a live boot CD or USB, mount your Hard Drive, navigate to /home/"user"/ and then delete the hidden .Xauthority file in your home directory?


    If you use an Ubuntu live CD/USB you will probably have to navigate to the home directory on the Linux partition.

    Once you are in the correct directory, use the terminal command...

    Code:
    sudo rm -rvf ./.Xauthority
    It should provide a verbose output of "removed './.Xauthority'" if successful.



    Otherwise you can just use Puppy Linux (which runs in root), mount the harddrive (by clicking on the Hardrive's Icon on the Desktop), and navigate to the home folder using GUI. You can then "show hidden folders" and then delete the .Xauthority file.

    Otherwise you will need to wait for someone else's help with this issue. Those are the only ways I know how do it.

    Re: Login Loop

    I cic Ctrl+Alt+F1 and got a prompt. To do that I was asked for a password that seemed to work (I only use one password for not financial things). So I was in the proper user.
