I should really do a Show HN of my X11rdp-o-Matic script, which automatically builds and installs X11rdp/xrdp from the github repo - it's been in existence for 2 years and I update the script(s) with enhancements from time to time.
xrdp and the X11rdp back-end X server is in constant and full development, with an actual Xorg module being worked on as well.
