Ubuntu 12.04 xrdp failed to load session 'ubuntu'

This error is caused by xrdp trying to run the  Ubuntu desktop when it is not installed. This can happen when you install  gnome-classic desktop only. There are 2 files you need to worry about: /etc/xrdp/startwm.sh which should have: . /etc/X11/Xsession at the end. (there is a space between '.' and '/etc') and ~/.xsession  (Don't worry if there isn't – it just means you haven't created it yet) This file should have: gnome-session --session=gnome-classic restart xrdp with: /etc/init.d/xrdp restart Connect with "sesman-Xvnc" settings.
