I've been trying to extend my screen to my iPad (iPad pro 12.9 A1652", iOS 16.7.8) over RDP for when I work at home.
I followed this guide and similarly in this guide but have failed to get it to work despite spending inordinate amounts of time on it.
It does make the connection, but something isn't working right with the auth. I've tried all manner of different user/password combinations but none have worked. It just bombs out right after auth. I can see the following in the logs:

I've got biometric login enabled and have tried both in wayland and x11.
I'm wondering if it's related to this bug in FreeRDP. I did look at manually updating to the suggested version of FreeRDP that does not contain the auth bug (2.10.0) but the steps seemed a little above my pay grade so decided against for fear of borking something else up.
I think you would be better using TightVNC. I used to work as a Vision Support Technician and an Advisory Teacher for the Vision Impaired working for another service wrote a guide on implementing Tight-VNC which worked in school setting using i-Pads.
May take some time to find it.
Do you mean by that screen sharing? Tight-VNC would allow iPad to view the desktop but not necessarily allow control of it, obviously would not be allowed in Education establishment. Will do some more digging.
No, I mean using the protocol so that you can use a second device on same local network like it's a connected external monitor, which is what gnome-remote-desktop is supposed to do.
In windows I used Splashtop Wired xDisplay or Spacedesk Display Monitor to achieve this.
