I followed the directions for installing a remote desktop server XRDP on my Lubuntu virtual machine. On the third step I am supposed to update the file
sudo nano /etc/xrdp/startwm.sh , for that update do I just go to the bottom of the file and add startxfce4 ?

I did that and it still does not work

Please advise, thank you

Follow these steps :

Step 1 – Install xRDP

Open Terminal (Crtl+Alt+T) and execute the following commands:

sudo apt-get update
sudo apt-get install xrdp

Step 2 – Install XFCE4 ( Unity doesn't seem to support xRDP in Ubuntu 14.04; although, in Ubuntu 12.04 it was supported ). That's why we install Xfce4.

sudo apt-get install xfce4

Step 3 – Configure xRDP

In this step, we modify two files to make sure xRDP uses Xfce4. First we need to create, or edit, our .xsession file in our home directory. We can either use nano or simply redirect an echo statement (easier):

echo xfce4-session >~/.xsession

The second file we need to edit is the startup file for xRDP, so it will start Xfce4.

sudo nano /etc/xrdp/startwm.sh

The content should look like this (pay attention to the last line and ignore . /etc/X11/Xsession):

#!/bin/sh
if [ -r /etc/default/locale ]; then
 . /etc/default/locale
 export LANG LANGUAGE
fi
startxfce4

Step 4 – Restart xRDP

You should edit only one file to have xfce desktop environment started

if you are the only user needing remote access, you can simply edit (or create) the ~/.xsession file and add the following line

• echo xfce4-session >~/.xsession

or if multiple users are using the system, you can edit the /etc/xrdp/startwm.sh and add the following line at the end

• echo xfce4-session >~/.xsession

This command will automatically populate the .xsession file o all the users

If you are using Ubuntu 14.04 (as mentioned in your question somewhere), you can try to get more information in the step by step guide provided here

Hope this help
Till next time
See ya
