I was trying to control Ubuntu 20.04 remotely via windows 10.
I installed xrdp with the scripts from https://c-nergy.be/.
After logging in on windows, the screen was refreshing but the mouse and keyboard did not respond.
The Ubuntu system is installed on a laptop, and the keyboard and mouse are normal.
Here is the log file.
