 +====== XRDP ======
 +
 +xrdp runs on a Linux system and allows for native Windows RDP to connect to it.
 +
 +**Note:** xrdp checks only if a session with the same geometry is already opened. It will start a new session if the geometry/​resolution doesn'​t match. This means if you connect using an external monitor initially, and resume with a different monitor with different resolution being sent, you will get a new session. Resolution settings are configurable via the RDP client display settings. (Full screen is the default)
 +
