My problem is I can’t login to a desktop as normal user and I can as administrator-root,
Any sugestion?
Hi @tompravi1 ! 
Let’s get some information:
- Get into the TTY using
Ctrl Alt F2orCtrl Alt Fn F2 - Try logging in here with your normal username and enter the password for that user (you would have entered this information during installation).
- Take a picture of the output you see and post it here.
