Hey,

I just customized new Kali linux (2020.3 - 5.6.0-kali1-amd64) when suddenly I wasn't able to do nothing in terminal. I rebooted the system and now I am not able to login back
with my created account. When I enter username and password, the screen just blink, and it is asking for username and password again. The credentials are correct cos when
using wrong credentials there is an error message. I can log in just with a ROOT account. When switching in terminal to created user it is working properly.

I am using KDE Plasma and lightdm-greeter.

Thanks in advance.
