Corrupt NVidia driver causes user to be stuck in the login screen

I was playing with dual monitors on my NVidia GTX 1050Ti card and at some point, the UI stopped to allow me to log in. It was going in the loop after each (correct) login.

Steps to fix it:

Press Ctrl+Alt+F1

or F2, F3

Log into in Command Line

Remove NVidia drivers

$ apt-get purge nvidia-*

Add repository

add-apt-repository ppa:graphics-drivers/ppa 

Refresh packages

sudo apt-get update

Install your NVidia driver  GTX 1050Ti driver 275.10

apt-get install nvidia-375

Reboot

sudo reboot

This has fixed it for me!
