I have installed LM20.4 XFCE and also LM20.4 MATE with the same problem.
The login screen is perfect, and when I valid my user account the screen seems with bad resolution or bad synchronisation, or other I don't know. The PC become unusable. Maybe just an configuration in command line can solve this, if somebody knows this and help me, thanks by advance.
