Installing Desktop Environment

Ubuntu servers are managed from the command line and do not have a desktop environment installed by default. If you run the desktop version of Ubuntu, skip this step.

There are various desktop environments available in Ubuntu repositories that you can choose. One option is to install Gnome, which is the default desktop environment in Ubuntu 20.04. Another option is to install Xfce . It is a fast, stable, and lightweight desktop environment, which makes it ideal for usage on a remote server.

Run one of the commands below to install the desktop environment of your choice.

Install Gnome:

sudo apt updatesudo apt install ubuntu-desktop

Install Xfce:

sudo apt updatesudo apt install xubuntu-desktop

Depending on your system, downloading and installing GUI packages will take some time.

Installing Xrdp

Xrdp is incuded in the default Ubuntu repositories. To install it, run:

sudo apt install xrdp

Once the installation is complete, the Xrdp service will automatically start. You can verify it by typing:

sudo systemctl status xrdp

The output will look something like this:

● xrdp.service - xrdp daemon
     Loaded: loaded (/lib/systemd/system/xrdp.service; enabled; vendor preset: enabled)
     Active: active (running) since Fri 2020-05-22 17:36:16 UTC; 4min 41s ago
  ...

By default Xrdp uses the /etc/ssl/private/ssl-cert-snakeoil.key file that is readable only by members of the “ssl-cert” group. Run the following command to add the xrdp user to the group :

sudo adduser xrdp ssl-cert

Restart the Xrdp service for changes to take effect:

sudo systemctl restart xrdp

That’s it. Xrdp has been installed on your Ubuntu server, and you can start using it.

Xrdp Configuration

The Xrdp configuration files are located in the /etc/xrdp directory. For basic Xrdp connections, you do not need to make any changes to the configuration files.

Xrdp uses the default X Window desktop environment (Gnome or XFCE).

The main configuration file is named xrdp.ini . This file is divided into sections and allows you to set global configuration settings such as security and listening addresses and create different xrdp login sessions.

Whenever you make any changes to the configuration file, you need to restart the Xrdp service.

Xrdp uses startwm.sh file to launch the X session. If you want to use another X Window desktop, edit this file.

Configuring Firewall

The Xrdp daemon listens on port 3389 on all interfaces. If you run a firewall on your Ubuntu server , you’ll need to open the Xrdp port.

To allow access to the Xrdp server from a specific IP address or IP range, for example, 192.168.33.0/24, you would run the following command:

sudo ufw allow from 192.168.33.0/24 to any port 3389

If you want to allow access from anywhere (which is highly discouraged for security reasons), run:

sudo ufw allow 3389

For increased security, you may consider setting up Xrdp to listen only on localhost and creating an SSH tunnel that securely forwards traffic from your local machine on port 3389 to the server on the same port.

Connecting to the Xrdp Server

Now that you have set up your Xrdp server, it is time to open your Xrdp client and connect to the server.

If you have a Windows PC, you can use the default RDP client. Type “remote” in the Windows search bar and click on “Remote Desktop Connection”. This will open up the RDP client. In the “Computer” field, enter the remote server IP address and click “Connect”.

On the login screen, enter your username and password and click “OK”.

Once logged in, you should see the default Gnome or Xfce desktop. It should look something like this:

You can now start interacting with the remote desktop from your local machine using your keyboard and mouse.

If you are running macOS, you can install the Microsoft Remote Desktop application from the Mac App Store. Linux users can use an RDP client such as Remmina or Vinagre.
