Press Ctrl+Alt+F1 and login into the shell.
Now run ls -lA | grep 'Xauth*'. you'll see the line
-rw------- 1 root root 53 Nov 29 10:19 .Xauthority
then you need to do chown username:username .Xauthority and try logging in (you may also need to do the same for for .ICEauthority).
Else, do ls -ld /tmp. Check for the first 10 letters in the left: they should read exactly so: drwxrwxrwt.
drwxrwxrwt 15 root root 4096 Nov 30 04:17 /tmp
Else, you need to do sudo chmod a+wt /tmp and check again.
Now press Ctrl+Alt+F7 to reach the login screen again, and restart.
