I can get fullscreen mode if i installed xorgxrdp, plasma-workspace-x11. After editing startwm.sh in home directory and adding this parametr dbus-launch --exit-with-session /usr/bin/startplasma-x11 i can see fullscreen mode. On the xrdp login screen i choose Xorg.
But how to get fullscreen mode with Wayland via xrdp without x11 components?
