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

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

Well did you tried to double check on your display manager. That may be there is a clash between gdm & lightdm.

Try CLT+ALT+F1 login to your account and sudo service lightdm start
