Ubuntu 13.04 Login Loop

I have a problem with Ubuntu 13.04.

I cannot log in to my account. I put the right password but there is an endless loop. (if i put wrong pass, it says “Invalid password…”). Also, it doesnt show the small drop down menu with choices “Gnome fallback, Default, etc..”

If i login as guest, the desktop is clear, no bars, no menus, anything. Just right clicks works only.

I have already try this solution ( chown username:username .Xauthority ) but there is no “Xauthority” at ubuntu 13.04. (?)

Is the problem about lightdm?
Also, i tried sudo dpkg-reconfigure lightdm but it soesn’t work.

I use the recovery mode (root command shell or something like this) in order to try the above commands.

Has anyone a solution?

Thank you.

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

Try deleting $HOME/.profile, I had the same problem before, because I added a function into $HOME/.profile.

When I deleted the function, I could login again.
The original content of $HOME/.profile is

# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.

# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
    . "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Solution 2

The file you need to make your own again is /home/[yourUsername]/.Xauthority (the . is important!).
And be sure to follow the procedure in the first solution

Solution 3

I had a similar problem, but neither changing the ownership of ~/.Xauthority nor commenting the content of ~/.profile made a difference. To fix it I did the following

rm ~/.Xauthority
sudo apt-get install --reinstall xorg
sudo reboot

It took a little longer than normal to login, but I was able to. My guess is that the .Xauthority file became corrupted in some way.

Solution 4

lightdm may be a good place to look. I had a similar problem in 12.04LTS and discovered a problem with Cairo-dock. Here’s what I did:

boot
login ->returns to lightdm login prompt

CTRL+ALT+F1 ->gets you to shell

sudo more /var/log/lightdm/lightdm.log

mine showed an error loading cairo-dock, followed by a couple of errors. You may get a different error, but it’ll point you where to look next

Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
