Xrdp can't work on Nano

Hi,

I have installed xrdp into Jetson nano then I use Windows remote desktop to logon into it, I can see the big nvidia logo then the connection stopped.
I got this message:

If I run systemctl status xrdp on nano, I got this:

What could be the problem? I connected my Nano with my PC with direct cable.
(I can use vino/vnc without any issue as documented in nano’s readme document)

We don’t have official support for xrdp but only VNC.

I will let other forum users to share their experience of xrdp.

but the officially supported vnc is lagging, for example, If I move my mouse onto a button, I can observe the delay before the button’s color is changed.

Is vnc designed to be so slow?
