In this description, we will go through the settings inside or outside the server that we need to change in order for the services on the machine to work with the new IP address.

How to control your remote computer with Chrome Remote Desktop

This is because Google Remote Desktop on Linux machines basically starts a new session instead of using an existing desktop. In this description, after installing and starting the program, we make a setting that allows the remote control part to be connected to the same session on Linux host machines, which allows us to use the remote control system in the usual way.
