Press ctrl+alt+f1 then once you log in to command line try to create a file or folder to see if the problem is not lack of disk space. — nassim, May 18 '21 at 15:15
@ankushjamthikar, sorry I don't remember this issue at all, but from the top of my head maybe you can use a live CD or USB to delete some stuff? — Baha, May 12 '22 at 11:59

When the password entry screen appears on the display manager screen press Ctrl + Alt + F1. After that, you will get to the console. There enter login and then password.

sudo chmod -R u+w /home/user
cd /home/user
sudo rm -f .Xauthority .ICEauthority

go through live USB, when you start clicked to restore the system - it also helps

thanks, man! I've moved both .Xauthority and .ICEauthority to backup, and worked like a charm. – Eugene May 03 '18 at 10:02

Ctrl + Alt + F1 did not work in my case of Ubuntu 18.04 in VirtualBox, but Ctrl + F2 did take me to the command line.

My issues did not end there however, I simply could not issue any command (resulted in error "Command ... not included in the PATH environment variable") until export PATH=/usr/bin:/bin. But then, to my dismay, none of the procedures listed here helped. What worked is the answer by Prometheus and Chaos at https://askubuntu.com/questions/249363/my-ubuntu-system-is-asking-login-again-and-again-when-i-even-entered-the-correct

I have Ubuntu 19.10 and changing the PATH variable in /etc/environment caused asking the password again and again when I wanted to restart my machine. I used another environment variable in my PATH variable and Ubuntu didn't like it.

So as Arthur wrote I pressed Ctrl + F2 when it asked the password, logged in, realized the problem with echo $PATH, edited the PATH variable with nano /etc/environment, replaced the other variable in the PATH with its value, restarted my machine, and it works now.

I faced the same issue on my laptop and solved it by following below steps:

Press CTRLAltF1 and It will open the console.
Enter your username and press Enter.
Enter your username password and press Enter.
Run command: mv .Xauthority .Xauthority.bak
Run command: exit
Press CTRLAltF7 for graphical mode.
Try to login by entering your password.

I had the same problem on Ubuntu 16.04LTS 64bit. My nvidia driver was the reason of it. I dont't know the details. However removing nvidia-340 package fixed the trouble (apt-get remove nvidia-340).
