I am trying to get XRDP working with the latest Ubuntu 14 server. However, after my rdp client logs in all I get is a grey screen with an X in the middle. This is the error from my .xsession-errors file:

Xsession: X session started for  at Wed Apr  9 10:16:16 EDT 2014

The GUI environments I have tried after the base install of the server and how I installed them:

  1. sudo apt-get install ubuntu-desktop: Gets the grey screen when I use my RDP client
  2. sudo apt-get install xubuntu-deskop: Gets the grey screen when I use my RDP client
  3. sudo apt-get install xubuntu-desktop xfce4: Gets the grey screen when I use my RDP client
  4. sudo apt-get install xorg xfce4: The rdp client works but doesn't provide all of the tools that the Ubuntu and Xubuntu desktop provide.

I also tired going though this post with no success.

Does anyone have any suggestions that my help in getting XRDP to work with one of the standard Ubuntu desktops?

Already answered here: 13.10 XRDP problem with gnome-fallback

As you know by now, the ability to fire up a gnome-session with xrdp broke with Ubuntu 14.

Bug here: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1251281

Ubuntu 12 does not have this problem. This might be your solution. However it will be soon out of support so that is not an acceptable option for many.

XFCE4 + tightvncserver + xrdp is an option, but you said that is not acceptible. And you may run into problems with this too. See my post here: Ubuntu 14.x with xfce4-session desktop - Terminates abruptly

I have been hanging out in #ubuntu freenode IRC chatroom looking to see if anyone has an ETA on fixing gnome + xrdp. Nothing yet.

I would suggest trying another well supported Linux distro such as CentOS6 that does not have this issue.
