Try the following:
When you hit the log on screen type ctrlaltF1 to open a tty1 session.
Log in with your username and password.
Type
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.
1: Use GDM Instead RECCOMENDED
sudo apt-get install gdm && sudo dpkg-reconfigure gdm
Then select GDM and hit Enter.
2: Repair LightDm NOT RECCOMENDED
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
