3) What is expected to happen is when one installs xrdp on the host and attempts to use remmina or vinagre on a Ubuntu 14.04 client to RDP in, it works.

4) What happens instead is it shows a gray static screen as per attached screenshot. This would appear an issue with gnome-session as per client log:
