The notes below were adapted from How To Enable Remote Desktop Protocol Using xrdp on Ubuntu 22.04

• Ensure you have the Xfce Desktop Environment installed and working on the machine you want to access remotely.
  • Consult Xfce install info as needed.
• dnf install xrdp
• As root, make a backup copy of /etc/xrdp/xrdp.ini and then prepare to edit it.
  • You should be able to comment out the Xorg section and just keep the Xvnc active.
  • Modify the port=3389 line to a different number if you don't want to use the default.
  • systemctl restart xrdp
  • systemctl enable xrdp
• Modify firewall to allow xrdp or custom port:
  • firewall-cmd --permanent --zone=public --add-port=NNNN/tcp
  • firewall-cmd --reload
  • Note that if you want to remove a port, use --remove-port instead.
• Modify local router to forward to custom port if needed.
• Create a file $HOME/.xsession as 700 permissions and the following contents:
  • /usr/bin/dbus-launch --exit-with-session xfce4-session
• Use Microsoft Remote Desktop Connection to test access.
  • Don't forget to append a ":NNNN" for the port number if you are not using the default 3389.
