First of all, I know there are similar, already answered questions about this, I checked most of them, but I didn't find a solution. I've got a login loop problem in Ubuntu 18.04 (after entering the password the login screen comes back).
Then I've tried the CTRL + Alt + F1 combination and the following screen came up
With the CTRL + ALT + F2 combination the login screen came back.
While with CTRL + ALT + F3 I get this, same goes with tty 4-6 too.
Does anybody have any solution for my problem?
