Install xrdp on Ubuntu 20.04

NOTE: Before installing xrdp add any secondary language you need to your system
by using, NOT an RDP connection, but a direct access to it, i.e. through a console of the virtualization system if it’s a VM

# install xrdp sudo apt install xrdp -y sudo systemctl status xrdp  # the xrdp user must be a member to the "ssl-cert" group sudo usermod -a -G ssl-cert xrdp   # if UFW firewall is in use, # then you shoud open the RDP port 3389 for your LAN network # so google for "what is my public ip address" to find you public IP sudo ufw allow from PUBLIC_IP_ADDRESS to any port 3389 sudo ufw reload  # if you experience the black screen issue # then edit the /etc/xrdp/startwm.sh sudo nano /etc/xrdp/startwm.sh   # by adding the following lines # just before the commands that test and execute XSession  unset DBUS_SESSION_BUS_ADDRESS unset XDG_RUNTIME_DIR  # do not forget to restart the service (or the machine) sudo systemctl restart xrdp

A glitch

Switching languages does not work properly, at least when connecting from a MS Windows 10 system to Ubuntu through xrdp.

If you use the X button, upper right corner, to close the Windows RDP window, then the next time you connect to Ubuntu switching languages stops working.

The work-around I found is to NOT close the RDP window, but to log-out from Ubuntu, which closes the RPD window too by the way.

Tested on:

• Ubuntu 20.04 with GNOME 3.36.8
