The script hereafter is outdated and has been replaced by a newer version.  Please Check the Download page for latest version.

Hello World, 

Since Ubuntu 21.04 has been released (April 2021), it’s time for us to update and publish the latest version of our famous xrdp-installer script. As we tend to follow the Ubuntu life cycle, we tend to update our script to include supported version of Ubuntu Operating system.  This new release will basically include support for Ubuntu 21.04 but it will also introduce some important changes that you need to be aware of (no support for Ubuntu 16.04 anymore !!!)

The new version of our famous xrdp installation script will be set to 1.2.3 (i.e. xrdp-installer-1.2.3.sh).  This script replaces all previous versions.   

Note : This script should be seen as a quick maintenance release to include Ubuntu 21.04. A new version of the script is being worked out which will be released at a later time….

So, let’s go ! 

Overview

The xrdp-installer-1.2.3.sh script ease the installation and post-configuration actions of xRDP on top of Ubuntu Operating System.  This version is the latest iteration of the script which include support for Ubuntu 21.04 (recently released in April 2021). 

What’s new in this release (Version 1.2.3) ?

While the script structure and code has not changed drastically, Version 1.2.3 introduce some important changes that you have to be aware of. 

Removed Ubuntu 16.04 as supported OS !

Since Ubuntu 16.04.x has reached end of standard support, the xrdp-installer script has removed support for Ubuntu 16.04.x.    Version 1.3 of the script will not run on Ubuntu 16.04.x !  

If you still need to support Ubuntu 16.04.x, please use the xrdp-installer-1.2.2.sh version of the script to perform your xRDP installation. Use the script at your own risk as we will not provide anymore any updates for Ubuntu 16.04 Support 

Note : Visit our archive Repository page to retrieve previous version of the script

Added Ubuntu 21.04 as supported OS !

Since Ubuntu 21.04 has been released, we have adapted the script in order to include support of the latest Operating System version.  The script can be run against Ubuntu 21.04. 

Improved removed function  

The script allows you to uninstall the xRDP installation previously performed with the script.  The previous script was removing only basic information from the system. Script version 1.2.3 checks more settings and delete files that are not needed anymore.   There is still room for improvements and we will probably perform that in the next iteration of the script 

Minor Bug Fixing, Cleaning up code 

We have found some small bugs or minor issues that have been fixed or improved in this release. We have also modified a little bit the code structure but nothing major  

Download the Script 

The script can be download at this location  :    xrdp-installer-1.2.3.zip 

Note : All the xrdp scripts can be found at https://www.c-nergy.be/products.html

How to Use the Script

A downloadable version of the script is available at the bottom of the post

The xrdp-installer-1.2.3 script will work in a similar way as the previous versions. The following section will explain how to download, extract, set executable mode and perform the installation using the script.  The script provides some switches that can be used to customize the installation process.

So, let’s see how this would be working…. 

Disclaimer

Script version & Supported Ubuntu Version

The xrdp-installer-1.2.3.sh script will support the following Ubuntu operating system version 

• Ubuntu 18.04.x
• Ubuntu 20.04.x
• Ubuntu 20.10.x
• Ubuntu 21.04.x

Ubuntu 16.04.x is not anymore a supported OS version with the xrdp-installer-1.3.sh script ! 

Step 1 – Download the script 

To download the script, you have multiple options.   You can from a Terminal issue the following command 

wget https://www.c-nergy.be/downloads/xRDP/xrdp-installer-1.2.3.zip

You can also simply use your browser and click on the link to download the script :  

•  xrdp-installer-1.2.3.zip

Step 2 – unzip the file 

After downloading the zip package containing the file, you will need to unzip it first. To unzip the package, you can use the Terminal console and issue the following command 

unzip xrdp-installer-1.2.3.zip 

You can also use the GUI and the Nautilus file manager to select the downloaded package, right-click on it and select the option Extract Here

Step 2 – Set Execute Right on the script

Download the xrdp-installer-1.2.3.sh script to your system, extract content and mark it as executable . To do this, perform the following action in a terminal console

chmod +x  ~/Downloads/xrdp-installer-1.2.3.sh

Note : Adjust the path where the xrdp-Installer-1.2.3.sh script to reflect your environment

Step 2 – Run as normal user 

The script needs to be run as a normal user.  The script will start running and will prompt you for password when sudo actions are initiated.  If you run the script as root or using sudo command, the Download folder does not exist for the root user and the script fails to run as expected.   To overcome this situation, the script also check which user is executing the script. If the script is run under sudo or root accounts, a warning message will be displayed and the script will not execute

Step 3 – Switches and parameters 

The xrdp-installer-1.2.3.sh script can be executed as is (with no parameters or switches). This will perform a standard (and basic) installation of xRDP.  No sound or custom xrdp login script will be made available.  However, remote desktop, drive redirection and clipboard redirection would be available with this installation mode.  

The xrdp-installer-1.2.3.sh script accept also some additional parameters that will help customize the xrdp installation and enable additional features.  The script provides the following parameters 

--help or -h          => will display a basic help menu
--sound or -s         => will enable sound redirection 
--loginscreen or -l   => will customize the xRDP login screen 
--remove or -r        => will remove the xrdp package 
--custom or -c        => will perform a custom installation (i.e. compiled from sources)

Step 4 – Perform xRDP installation using the script 

The following sections will provide some examples and scenario on how you can use the script….. 

Standard Installation – No Parameter

As mentioned above, you can decide to use the default xrdp package available in the Ubuntu repository and perform a basic installation which will provide you remote desktop capability and will also customize the remote sesssion.  The script will ensure that the same look n’ feel will be maintained when the user logs on locally or remotely. 

To perform a standard installation, you execute the script with no parameters.  Open a Terminal console, browse to the location where the script has been downloaded and issue the following command 

 ./xrdp-installer-1.2.3.sh

When the xrdp installation package will start, you be requested to enter your password. Provide the password and proceed with the installation. Wait for completion of the script.  The machine will not reboot automatically when done so you can review the actions performed by the script….

Standard Installation with Parameters

The script can be used to perform a standard installation and still passes some parameters to get the most of the xRDP packages and their features.  For all the Ubuntu versions, we could use the following combination of parameters 

./xrdp-installer-1.2.3.sh -s      (this would enable the sound redirection) 
./xrdp-installer-1.2.3.sh -l      (this would customize the xrdp login screen -see here)

Obviously, you can combine the switches (any order) to have more features enabled  

./xrdp-installer-1.2.3.sh -s -l      (this would enable the sound redirection and customize the xrdp login screen)

Important Notes

The script can be run multiple times on the same machine.  If you have run initially the script with no parameters but you decide afterward to enable additional features, the script can be re-executed and the additional features will be enabled.  

Custom Installation – Default Installation 

Custom installation script is really flexible. Custom installation means that the script will compile the xrdp package from the source binaries. The custom installation script always uses the latest xrdp package version available 

To perform a custom installation, you will need at minimum to pass one parameter.  The following command line shows you how to perform a custom installation  

./xrdp-installer-1.2.3.sh -c     (this would perform a custom installation but will not enabled adv features like sound redirection or custom login screen)

Custom Installation – Additional Options  

If a user wants to enable additional features, you will pass some additional parameters as shown in the following examples 

./xrdp-installer-1.2.3.sh -c -s     (this would perform a custom install and enable sound redirection)
./xrdp-installer-1.2.3.sh -c -l     (this would perform a custom install and customize xrdp login screen)
./xrdp-installer-1.2.3.sh -c -l -s  (this would perform a custom install, enable sound and customize login screen)

Important Notes

The script can be run multiple times on the same machine.  If you have run initially the script with no parameters but you decide afterward to enable additional features, the script can be re-executed and the additional features will be enabled.  

Remove Installation option

This version of the script also ship with the option to remove xRDP package.  The removal option should be only used  if you have uses this version of this script to perform the installation.  To remove the xrdp package, you would simply execute the following command  

./xrdp-installer-1.2.3.sh -r     (to remove the xrdp packages)

Step 5 – Test your configuration 

After the script has run and after the reboot/shutdown and start process, it’s time to test and see if you can indeed perform a smooth remote connection to your Ubuntu machine.  Start your favorite rdp client and simply enter your credentials and start testing your installation.  If everything is ok, you will see a similar Desktop interface where Gnome Desktop is used and the Dock is visible. 

Known issues and limitations 

Known Issues 

Drive Redirection  

To redirect your drives to your xrdp remote session, you have to ensure that the only option selected in the local resources tab are the Clipboard option and the drive option. Check the screenshot below and ensure that you have the same settings.

Click on picture for better resolution

Click on picture for better resolution

When these settings have been set accordingly, you should see the thin client folder populated with redirected drives coming from your Windows machine.

Sound redirection Issue

If the Sound redirection option has been selected, rebooting the Ubuntu system is not enough and the sound redirection might not work.  if the sound redirection option has been selected, you will have to shutdown your Ubuntu machine and then start it again in order to ensure that the sound redirection feature would work as expected. 

Sound redirection is not working as expected on Ubuntu 19.10 and later  The modules are created and copied to the correct location. However, the xrdp sink modules are never loaded in the remote session or randomly loaded in the remote session.   To fix this, you simply need to execute the following command within your remote session and the sound will start working 

pulseaudio -k

Black Screen or disconnected immediately after connecting

As mentioned and explained multiple times,  this situation will happen (or can happen) when the same user account is used concurrently locally and remotely.  In other words,  the problem is related to the fact that the same user account is already logged in locally and a remote connection is attempted at the same time.  With xRDP software solution, a specific user account can be logged on either locally or remotely but not both….  

You can read more information and some workarounds (provided as is) to try to fix the issues in the following posts 

• xRDP – xRDP shows only black screen after authentication windows – HowTo Fix !
• xRDP – Allow multiple sessions (local and remote) for the same user – HowTo

Limitations

Switch between standard and Custom install

This version of the script can be run multiple times on the same machine.  However, because of this new behavior, you cannot perform a standard installation and then decide to perform the custom installation.  Once you have selected your installation mode, you will have to stick to it.  This is kind of checked by the script.  

So, if you have performed a standard installation but afterwards you might want to use the custom installation option, the script will ignore the request.  If you want to move from standard install mode to custom mode (or vice versa), the correct process is 

• remove xrdp (using the xrdp-installer-1.3.sh -r option) 
• perform a new installation using your selected installation mode (standard or custom install mode)
