xRDP – Easy install on Ubuntu 16.04,18.04,19.04 & 19.10 (xrdp-installer version 1.1)

 

  The script hereafter is outdated and has been replaced by a newer version.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

Hello World, 

Recently, we have released the latest version of our famous xrdp installation script (i.e. xrdp-installer-1.0.sh).  The latest version of the script is merging and consolidating the standard installation script and the custom installation script.  The xrdp-installer-1.0.sh script is basically replacing any previous versions of the script that has been released so far.  The script has been made available with the release of Ubuntu 19.10.   We have received positive feedback on the script.  However, some minor issues have been detected and we have decided to update already the script and release a new version of the script… 

So, let’s go ! 

Overview

Initially, this script should have been released with the next LTS Ubuntu release (i.e. Ubuntu 20.04).  However, we have decided to release it with Ubuntu 19.10 which offers us the opportunity to detect possible bugs and issues and fix them before the next LTS release.  This seems to be the good strategy as we have indeed detected some minor issues that have been fixed in this version of the script (version 1.1).   

Note : This version of the script is stable but need to still go through some more validation process…..

Script version & Supported Ubuntu Version

The script version will be set to 1.1. So, the xrdp-installer-1.1.sh script will support the following Ubuntu operating system version 

  • Ubuntu 16.04.x 
  • Ubuntu 18.04.x
  • Ubuntu 19.04
  • Ubuntu 19.10 

Prerequisites and assumptions  

The following conditions should be met in order to have the best results while using the script

  • We assume that your machine is connected to internet while performing the installation.  This is needed as additional packages and software needs to be downloaded and installed on your Ubuntu machine
  • The script runs against a supported Operating system (Ubuntu 16.04.x, Ubuntu 18.04.x,Ubuntu 19.04, Ubuntu 19.10)
  • The Official Ubuntu distribution needs to be used (we do not support other Ubuntu flavors – so far !!) 
  • No additional Desktop interface is used ( xRDP session will be showing Ubuntu Gnome Desktop with the Dock menu or Unity if running Ubuntu 16.04)
  • Sound functionality is present on the computers if you sound feature is available as well

The Script 

The script has been modified slightly and try to improve the script usage.   The following modifications have been included in the script 

  • the script is not using hard coded folder ~/Downloads anymore. We are using a variable to detect the Downloads folders on the system.  This ensure that the script could theoretically run on non english configured systems. (Thanks to Olivier for the Suggestion :-))
  • the script check if group membership ssl-cert contains or not the xrdp user.  This action ensure that no warning message is thrown if the user is already member of the group
  • checkinstall run with additional parameters (i.e. package version for xrdp).  This is to avoid that possible ubuntu xrdp updates breaks the custom install performed ((Thanks to Olivier for the detecting the issue :-))
  • additional check that detect if the script has been run more than once on the system. 

Important Note :

If you copy/paste the script, you might encounter some issues because font formatting might be not maintained during the copy/paste operation. Please ensure that format is  accurate before launching the script. A downloadable version of the script is available at the bottom of the post

How to Use the Script

The xrdp-installer-1.1 script will work in a similar way as the previous versions.  First, we will need to set the execute permission on the script.  Then, you will need to choose between standard and custom installation.  Finally, you would need to decide if additional options would be enabled or not…   So, let’s see how this would be working…. 

Step 1 – Set Execute Right on the script

Download the xrdp-installer-1.1.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-1.1.sh

Note : Adjust the path where the xrdp-Installer-1.1.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-1.1.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-1.1.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-1.1.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….

Important Notes

If you are running the script on Ubuntu 16.04.x, the custom installation will always be performed even if you have not specified any parameters.  This is because Ubuntu 16.04.x ships with a really old xrdp package (version 0.6) and does not provides all needed features. The custom installation provide drive redirection,clipboard and access to Unity Desktop

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-1.1.sh -s      (this would enable the sound redirection) 
./xrdp-installer-1.1.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-1.1.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 and help avoiding issues like we have encountered in Ubuntu 18.04.x (see here,here and here).  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-1.1.sh -c     (this would perform a custom installation but will not enabled adv features like sound redirection or custom login screen)

Important Notes

If you are running the script on Ubuntu 16.04.x, the -c switch will be ignored and a custom installation process will be performed. This is because Ubuntu 16.04.x ships with a really old xrdp package (version 0.6) and does not provides all needed features. The custom installation provide drive redirection,clipboard and access to Unity Desktop

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-1.1.sh -c -s     (this would perform a custom install and enable sound redirection)
./xrdp-installer-1.1.sh -c -l     (this would perform a custom install and customize xrdp login screen)
./xrdp-installer-1.1.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 the script to perform the installation.  To remove the xrdp package, you would simply execute the following command  

./xrdp-installer-1.1.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.  Remember that a user can either be logged on locally or logged on remotely on the machine when working with xRDP solution.  If the user, performing the remote connection, is logged into the system locally the remote connection will start but will be terminated immediately.  This is the way it works nowadays. 

So, ensure that the user performing the test is not locally logged on, start your favorite remote desktop client and perform your connection.  Based on your options, you will be presented either with the green xrdp login screen or with the custom login screen (purple background). 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 

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.  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

For Detailed information, see post below

xRDP – Sound not always working on Ubuntu 19.10 – Quick Fix

Limitations

One session per user limitation

Only one session is allowed per user.  This means that if a user is logged on locally on the Ubuntu machine, the user will not be able to perform a remote session (the xRDP connection will initiate but will end up immediately).  If a user is logged on remotely on the system, it will not be able to login locally (if the user tries to login locally, the login screen will loop and the login screen will be presented again to the user) 

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-1.1.sh -r option) 
  • perform a new installation using your selected installation mode (standard or custom install mode)

  1. @Chandrashekaran,

    Performance are not really great when using xRDP against Ubuntu 16.04 + Unity. You could achieve better (acceptable performance) if you would xrdp to more recent Ubuntu releases (18.04, 19.10, or even Ubuntu 20.04) which will be released in a few days…. We never really worked with multiple monitor setup but this might be an interesting topic to investigate..

  2. Hello Griffon,

    after testing your script on a few different 16.04. machines I found another small issue.

    The HWE check doesn’t work reliably on some installations. When xserver-xorg-core status is “config-files” rather than “not-installed” it is falsely assumed than a non-hwe version is installed.

    Due to dpkg returning 1 in both “package not found” situations and in case of internal errors, I would propose to make the check more explicit and do something along the lines of

    check_hwe()
    {
    Release=$(lsb_release -sr)
    echo
    /bin/echo -e “\e[1;33m |-| Detecting xserver-xorg-core package installed \e[0m”

    xorg_no_hwe_install_status=”$(dpkg-query -W -f =’${Status}\n’ “xserver-xorg-core”)”
    xorg_hwe_install_status=”$(dpkg-query -W -f =’${Status}\n’ “xserver-xorg-core-hwe-$Release”)”

    if [[ “$xorg_hwe_install_status” =~ \ installed$ ]]
    then
    # – hwe version is installed on the system
    /bin/echo -e “\e[1;32m |-| xorg package version: xserver-xorg-core-hwe \e[0m”
    HWE=”yes”
    elif [[ “$xorg_no_hwe_install_status” =~ \ installed$ ]]
    then
    /bin/echo -e “\e[1;32m |-| xorg package version: xserver-xorg-core \e[0m”
    HWE=”no”
    else
    /bin/echo -e “\e[1;31m Error checking xserver-xorg-core flavour \e[0m”
    exit 1
    fi
    }

  3. @Andrej,

    perfect timing 🙂 As Ubuntu 20.04 is about to be released, we have been working on the script and we
    have updated slightly the script… we have indeed notice the issue just recently (as more people were encountering issues) but we didn’t had the chance to look at a possible workaround….

    We will test your proposal and if we are ok with it, we will use it…We will credits you for the update in vers 1.2

    Thank you for your help and the positive feedback provided

  4. Hello, thanks for the very useful script and articles regarding xrdp.

    By the way, I prefer traditional GNOME Fallback desktop.
    Following .xsession/.xsessionrcs support many desktops.
    Multiple users can execute different desktops simultaneously.
    Local user can select desktop from GDM menu.

    Following steps are enough.
    – Skip fix_theme() in xrdp-installer-1.2.sh (copy /etc/xrdp/startwm.sh.griffonl to /etc/xrdp/startwm.sh).
    – Put following .xsession/.xsessionrc in user’s home directory.

    GNOME Flashback works on 20.04, 18.04 and 16.04.
    Ubuntu desktop works on 20.04 and 18.04.
    Unity desktop works on 16.04, though there is an issue.

  5. Thanks for your guide!! Its’s amazing…..but i have a small problems. for the moment i just took the part to get a gnome session similar to the local adding:

    cat < ~/.xsessionrc
    echo export GNOME_SHELL_SESSION_MODE=ubuntu
    export XDG_CURRENT_DESKTOP=ubuntu:GNOME
    export XDG_CONFIG_DIRS=/etc/xdg/xdg-ubuntu:/etc/xdg
    EOF

    to the Startwm.sh

    Sometimes this modification it is not applied, seems not to be able to create the .xessionsrc file under the users’s home. Basically in some case even if i modifying the starwm.sh seems don’t have any effect and i don’t know why?

    Can you help me? Thanks in advance!

  6. Hello Giovanni,

    We have used the script and test it and so far we have not encountered the issue. The .xsessionrc is created all the time.
    We will need to take a closer look into this as we never had such issue….
    will try to perform some additional tests using your specific scenario

    Till next time
    See ya

  7. Just wanted to say thanks for automating this setup. I missed a setting somewhere and was stuck on the post-authentication blank screen. This fixed it and saved me a lot of time.

  8. Thanks for doing this. However, I used the script for Ubuntu 20.04.4 after I had installed xrdp with apt and experienced two mayor problems:

    – Dock is not shown on the left side (it seems to be excluded from the transmission)
    – Logging in after logging out gets you stuck after the password.

    Running your script did not change this. Both problems still persists.

  9. @Ben,

    Thank you for visiting our blog and sharing your findings… First of all, the script version 1.1 is outdated and should not be run against Ubuntu 20.04 version. You should have tried the latest version of the script version 1.3
    If you have used the script after installing manually xrdp software, this might not have executed full set of instructions… (but it should have been working)

    Dock not showing up means that your ~/.xsessionrc is not populate accordingly. So, if you have used the script, you should have the file /etc/xrdp/startwm.sh populated with the following information (in the beginning of the file)

    #!/usr/bin/env bash
    #
    # This script is an example. You might need to edit this script
    # depending on your distro if it doesn't work for you.
    #Improved Look n Feel Method
    cat < ~/.xsessionrc
    export GNOME_SHELL_SESSION_MODE=ubuntu
    export XDG_CURRENT_DESKTOP=ubuntu:GNOME
    export XDG_CONFIG_DIRS=/etc/xdg/xdg-ubuntu:/etc/xdg
    EOF

    If this is missing or does not reflect what’s shown above, this might explain why the dock bar is not showing in your xRDP Session. So, edit the file /etc/xrdp/Startwm.sh with admin rights and populate it with the info provided above, restart the xrdp service and try again.

    For the login/logout issue, not sure what you mean…. If you see the xrdp login box, digit username/password, what do you get… a dialog box message stating that the password is not correct or do you simply see a black screen after login process

    If dialog box, can you check that the keyboard layout is the one you thinking it is. To be sure, type the password in the user name dialog box so you can see if there is a keyboard issue or not
    if it’s a black screen (do not think so); you should ensure that only one session for your user account exists..So either you are logged on locally or remotely but not both at the same time

    Hope this help
    Till next time
    See ya
