I couldnt connect my remote ubuntu desktop by xrdp. Unfortunately, I wasnt able to use nomachine, either. I wonder what problem it is. I ve read these issue like mine but I couldnt solve it .

First thing is to make sure you're not using the same account for xrdp as you use to log in to the box normally. This is a common problem and is in the FAQ

Yep, I ve used this before in ubuntu machine 20/22, but today my machine cracked. I think its of some build dependency question

The session is finishing early:-

[20231216-14:51:41] [WARN ] Window manager (pid 3124, display 10) exited quickly (0 secs). This could indicate a window manager config problem

Do you have any useful information in ~/.xsession-errors?
