I installed Fedora Mate Compiz on my desktop machine – but I wanted to also be able to access the desktop remotely using RDP

To do so –

yum -y install xrdp 
firewall-cmd --permanent --zone=public --add-port=3389/tcp
firewall-cmd --reload
systemctl start xrdp.service
systemctl enable xrdp.service

To prevent the “xrdp could not acquire name on session bus” error message, do the following

For each existing user account

echo "unset SESSION_MANAGER" > ~/.Xclients
echo "unset DBUS_SESSION_BUS_ADDRESS" >> ~/.Xclients
echo "exec mate-session" >> ~/.Xclients
chmod 700 ~/.Xclients

To automatically generate the above settings for all future accounts you may create:

echo "unset SESSION_MANAGER" > /etc/skel/.Xclients
echo "unset DBUS_SESSION_BUS_ADDRESS" >> /etc/skel/.Xclients
echo "exec mate-session" >> /etc/skel/.Xclients
chmod 700 /etc/skel/.Xclients

You are ready to go!

Tested on: Fedora release 31
