Does the current state of development with KDE 6.0.x and Wayland fanfare permit the setup of remote RDP style login with a desktop backed by a virtual screen. It doesn’t have to be point and click, willing to play with setup.
I am aware of the workaround hacks like NoMachine that disable keyboard/mouse/monitor on connection but I’d like a truely not backed by physical session remote desktop.
If not, does anyone know if this is on roadmap for 6.1?
I think 6.1 comes next month.
That being said there is krdp have you tried it?
I can’t get it working but I’ve read good things.
krdp with krfb acts more like a teamviewer for hijacking current sessions connected to real keyboard/mouse/monitor but slightly worse as you still need to confirm to entry to the current session. I tried it months ago it wasn’t practical, leaving the coffee shop to go accept my remote session back home and come back and hope laptop was still there… 
I agree. It is somewhat surprising that there hasn’t been more interest in developing headless session remote desktop functionality.
There are some good commercial alternatives but not many free ones. X2go I think is the best/fastest but no Wayland. And there is an annoying bug that have persisted for many years, and there seem to be problems with win11 for some reason. Xpra and xrdp are noticeably slower.
Haven’t tried the RDP connect feature in kde, but if it is snappy like RDP in windows and would support headless sessions, that would be amazing.
Most of the time it’s ok without a desktop but on occasion it’s really good to have.
