Solution 1

I was facing this issue after adding export PATH=$JAVA_HOME/bin:$PATH in /etc/environment and /etc/profile files.

Solution:

On Login Page

1. Go to the command line - Ctrl+Alt+F1 or Ctrl+F2
2. Enter your username & password
3. sudo nano /etc/environment and remove PATH=$JAVA_HOME/bin:$PATH
4. sudo nano /etc/profile and remove PATH=$JAVA_HOME/bin:$PATH

Note: If the sudo and nano commands are not working for you, try this commands

/usr/bin/sudo /usr/bin/nano /etc/environment

/usr/bin/sudo /usr/bin/nano /etc/profile

Solution 2

I recently faced the same problem in my Ubuntu 14.04. I tried every solution present on Internet. after getting frustrated I tried to do something similar to what I thought is appropriate. I deleted the .profile file and restart system, after that I was able to login to same user. Following are the steps :

• Press CTRL + ALT + F3 to go to TTYs.
• Type: sudo mv .profile .profile.backup
• Then Type: sudo reboot

Does logging in as guest work? Does it work if you select a different session type, like Ubuntu 2D? Also, are you able to log in non-graphically in a virtual console? To attempt this, press Ctrl+Alt+F1 and enter your username and password as prompted. As you enter your password, you won't see any placeholder characters (like *). That's OK, just type it in and press enter. If you're able to log in, please run df -h and report the output. (The best way to provide this information is to edit your question.)

Close voter(s): This might be a duplicate of something, but it is not a duplicate of any question about how to reset a password. Here, the problem is that login succeeds but the display manager fails to start a desktop (or starts one but it terminates immediately).

Please use the search on this site using login screen loop and you'll find some similar questions. Attempt proposed solutions from there and if it fails, include the steps and results here. With the currently provided information it's not answerable, I'm afraid.

Ctrl+F2 for Ubuntu in VirtualBox brings the command prompt
