I’m been researching for remote desktop on linux for a while. Finally few weeks ago I can setup xrpd server, but it only work in plasma-x11 session on my arch.
Now it works flameless in my network even with vpn across internet.
But kde dev team said x11 will drop from developement. So i guess there is other options for acces to my desktops across my vpn just like now with any windows android or linux with freerdp client.
