I have setup a server running XRDP as a way to allow me to RDP from windows host into this system. The account I have set it up with is able to successfully RDP into the system.
However, none of the other users can. After they authenticate to the XRDP interface, the screen is just a light blue solid background.
My suspicion right now is that there is a setting somewhere that needs to configured to allow other users. I have found some articles which say you need to edit a startup script to echo the desktop into the config but I do not think these were right.
As a troubleshooting measure, I rolled back the VM to a pre-XRDP state. Re-installed the service and had and identical outcome.
