On Jessie, with the Rpi3B, it is simple to enable xrdp:
sudo apt-get update sudo apt-get install xrdp
But with the new Rpi3B+ which requires Stretch, it has a problem.
It will still allow you to get to the login screen, but then after supplying the credentials it then goes to a blank screen.
How to make xrdp work with Stretch on the new Rpi3B+?
