Standard XRDP installation on Ubuntu 16.04

Assumptions

For this post, we have make some assumptions.

Ubuntu 16.04 (Final Release version) is used
The Mate-desktop will be installed on the machine (as alternative desktop environment)
We will configure our system to match on localized version (i.e. we are using a Belgian french keyboard)
Since Ubuntu 15.04, upstart has been replaced by systemd component. The systemd component is used in our scenario
No additional configuration is needed to reconnect to the same session if you are using the latest version of the xrdp package found in the Ubuntu Repository

Installation Process

Step 1 – Install XRDP Package from Ubuntu Repository

A standard installation for us means that we will be using the xrdp package available within the Ubuntu repository. To install the xrdp software from Ubuntu repository, you will need to issue the following command in a terminal.

sudo apt-get install xrdp

Because of the sudo command, you will be prompted for a password. After entering your password, you will be asked to confirm your action by pressing Y (see screenshot below)

Step 2 – Install an alternative Desktop

xrdp and Unity desktop (or Gnome 3) are not working well together. If you do not install another desktop environment, when you will try to connect to your Ubuntu machine, you will see only a gray screen. The workaround to this situation is to install an alternate desktop that can work with xrdp software solution.

Our preferred desktop alternative is Mate-Desktop. This post will show you how to install the Mate-Desktop and have it working with the xrdp software solution.

To install the Mate-desktop, issue the following command from the Terminal Session

sudo apt-get update

sudo apt-get install mate-core mate-desktop-environment mate-notification-daemon

Note :

Desktop interface such as xfce, LXDE,LXQT, KDE are all potential candidates. Check the following links for more information and installation and configuration procedures

Step 3 – Configuring xRDP to use your desktop environment

At this stage, we need to configure our system in order to tell xrdp that an alternate desktop needs to be used. In our case, we have to tell xrdp that we want to use Mate-Desktop as alternate desktop. With the previous version of Ubuntu, you would need to create the ~/.xsession file. In Ubuntu 16.04, it seems that this approach is not working anymore. We need to configure the system differently when working with Ubuntu 16.04

Starting the alternate desktop environment

Important Note :

In our scenario, we have installed mate-desktop, If you have installed another Desktop alternative, you will have to adapt the configuration of the startwm.sh file to reflect your settings.

If you use the ~/.xsession file approach, you will experience the same symptoms as before i.e. grey screen. We will need to configure the system in a different way. To have xRDP working in Ubuntu 16.04, you will need to update the /etc/xrdp/startwm.sh file. To configure this, issue the following command in your Terminal console

sudo sed -i.bak '/fi/a #xrdp multiple users configuration \n mate-session \n' /etc/xrdp/startwm.sh

Note :

Remember that the command above is to be used when you have installed the Mate-Desktop. If you have installed a different desktop environment, you will need to adapt the command accordingly. Please check the following links

Step 4 – Configuring xRDP Keyboard

By default, the xRDP login screen will use an en-us keyboard layout. You remote session will also be using the en-us keyboard layout. If you are using a different keyboard layout than the english one, you need to perform the following actions in order to update the configuration of the xrdp software.

In my case, I’m using a Belgian French keyboard, so I had to tell xrdp to use the belgian french keyboard as well. To do that, you need to perform the following actions :

Step 1 : You go to the /etc/xrdp directory

Step 2 : you issue the command setxkbmap -layout <%your layout%> to define which keyboard map/layout to use

Step 3 : create a copy of the km-0409.ini file into the same directory. It seems that this is the default file used by xrdp to define the keyboard layout. You will need to use sudo in order to be able to write into the directory

Step 4 : Check that you have a backup of your file by typing the dir or ls command

Step 5 : update the file by issuing the following command sudo xrdp-genkeymap km-0409.ini

Step 5 – Reconnect to the Same Session

Since Ubuntu 14.10, a new xrdp package has been made available in the Ubuntu repository. This package fixes a long time issue related to the fact that users could not reconnect to the same session. If you are using the package xrdp 0.6.1-1, you do not need to perform any customization, you will reconnect automatically to the same session.
