xorgxrdp is a collection of modules to be used with a pre-existing X.Org install to make the X server act like X11rdp. Unlike X11rdp, you don't have to recompile the whole X Window System. Instead, additional modules are installed to a location where the existing Xorg installation would pick them.

xorgxrdp is to be used together with xrdp and X.Org Server. It is pretty useless using xorgxrdp alone.
