I did some terrible typos in comment 5 and cant edit the message. Next time i will let my cat write the report for our sanity. Please accept my sincere apologies.
Blank session when connecting through rdp protocol from a Windows/Linux machine SUMMARY When attempting to remotely connect using rdp protocol from a Windows PC, I get logged in but after the splash screes is showed, I end with a blank (actually, black) session where I can't do nothing. 1- Login in your KDE Neon PC 2- Start RDP connection from a Windows PC (7 and 10, both were tested) or a Linux (Kubuntu 18.04) to your KDE Neon PC. 3- Login in the xrdp session manager window 4- Wait for the splash screen until it finishes 5- Now you have an empty, useless session in which you can't even logoff Operating System: KDE neon 5.20 KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 Kernel Version: 5.4.0-62-generic OS Type: 64-bit NOTE: As an additional detail, the same computer, booting the Kubuntu 18 it has also installed, with the same xrdp configuration doesn't run into this issue.
