Remote desktop connection - BPi-F3

Hi, I’m trying to setup the F3 board (with latest version of Bianbu) to use remote desktop connection (from Windows 10). I followed tons of similar procedures involving xrdp, tightVNC and so on, but even if the system said that my remote user is connected, the exported desktop session is totally blank. Any idea or suggestion on how to solve this issue? I already tried ot force SESSION variables but nothig happens.

regards
