I really wish there was a good remote desktop method that supported attaching to my "local" session but keeping the displays locked. Similar to how windows RDP works.
If I have to remote into my work machine from home, I have XRDP setup to make a separate session that I can have run simultaneously to my local session. It's fine, but if I could use the existing local session that would be superb (without unlocking my local displays while I'm not there is the big point)
GNOME has RDP/VNC abilities, but in my experience a) the screen has to be awake, or else it becomes none responsive, b) it only worked with one monitor IIRC, and c) it unlocks the local display. x11vnc has issue C.
I think KDE is working on improved Wayland RDP? Haven't seen if it satisfies this. Sadly though, my work IT doesn't support Wayland
