I had a similar issue when logging into Ubuntu GNOME, my issues was resolved by:

When you reach the black screen upon login, you could try pressing 'Ctrl + Alt + F1' and blindly type your username, press enter and then type your password. Press enter after this and a CLI environment should be displayed similar to a normal terminal.

From here, enter the command: startx which should start the unity 8 desktop environment.
