Try the following:

When you hit the log on screen type ctrlaltF1 to open a tty1 session.

Log in with your username and password.


sudo service lightdm stop

and then

sudo apt-get install --reinstall ubuntu-desktop

See if that solves your problem.

To clarify more on Musher's answer, it is a problem with Ubuntu's default display, as lightdm is being obsolete and unsupported. To fix this press Ctrl + Alt + F1 to open a temporary display-lacking terminal. If that doesn't work use Ctrl + Alt + F3 instead. Once there, there are a two options to solve lightdm.


 sudo apt-get install gdm && sudo dpkg-reconfigure gdm

Then select GDM and hit Enter.


 sudo apt-get purge lightdm && sudo apt-get clean
 sudo apt-get install lightdm && sudo dpkg-reconfigure lightdm
 sudo apt-get purge ubuntu-desktop && sudo apt-get clean
 sudo apt-get install ubuntu-desktop && sudo shutdown now -r
