Note: You may try and create an image using other Linux distributions with other desktop environments than those specified below, but due to the large variety of Linux distributions and desktop interfaces, we may not be able to officially support them. Having said that, our customers have been able to run their own setups using Strigo. Examples of other configurations can be found here.

If you wish to deliver your training using a Linux-based desktop, you've come to the right place. There are two steps you must follow to achieve that:

Make sure you have a properly configured lab image.
Set up the lab interface to show a desktop interface instead of the default terminal interface.

Make sure you have a properly configured lab image

Below is a detailed explanation of both methods for achieving this:

Using our preview images

The AMI IDs provided below are Strigo preview images that were pre-configured to support the desktop functionality on a Linux-based image. The current configuration provides an Ubuntu 22.04 LTS with the XFCE desktop environment with minimal pre-installed applications.

To be able to use a Linux desktop, do the following:

Add a new resource to your lab, click the Image button, and make sure to select the Custom tab. Use one of the following AMI IDs below:
eu-west-1: ami-0b32f4a77e48fcb24
eu-west-2: ami-032c3572d45404ef3
eu-west-3: ami-0842ef6d5d28dfc9d
us-west-1: ami-0e07d64097c85b619
us-west-2: ami-0c66d9067fb13e38c
us-east-1: ami-011f6718a3b3f313a
us-east-2: ami-0b2e72cfc3a8d6793
ap-southeast-1: ami-06e63b7a85515d728
ap-northeast-1: ami-03cc6320a82893b19
In the username field, use ubuntu.
Click the Edit Interfaces button and select Desktop under the default interface section.
Proceed as usual with configuring the rest of the class.

Note: You can use the aforementioned images as a base for your own custom images. Alternatively, if you would like to prepare a totally new custom image by following the instructions below.

Creating your image from scratch

Supported configurations

Due to the great variability in the Linux world, Strigo only officially supports a very narrow set of configurations:

Ubuntu 20.04 LTS
XFCE 4 Desktop environment
xrdp server

On an Ubuntu 20.04 server image run the following as root:

#!/bin/bash -e

apt-get update -y
apt-get upgrade -y

apt-get install -y xfce4 xfce4-goodies xrdp
echo "xfce4-session" > /home/ubuntu/.xsession
cat <<EOF > /home/ubuntu/.xsessionrc
export XDG_SESSION_DESKTOP=xubuntu
export XDG_DATA_DIRS=/usr/share/xfce4:/usr/share/xubuntu:/usr/local/share:/usr/share:/var/lib/snapd/desktop:/usr/share
export XDG_CONFIG_DIRS=/etc/xdg/xdg-xubuntu:/etc/xdg:/etc/xdg
EOF

chown ubuntu:ubuntu /home/ubuntu/.xsessionrc /home/ubuntu/.xsession

apt-get autoremove -y
apt-get clean -y

User requirements

The above snippet assumes that the username that will be used to connect to the running instance over RDP is ubuntu.

This user must be allowed to execute commands with sudo without being prompted for password.

For users that are familiar with Packer we also provide a public repository with all of the required configuration ready to run.

Set up the lab interface

In order for the desktop to show up inside the training environment, you will need to change the default interface for Linux-based images from Terminal to Desktop. You can do that using the Edit Interface functionality in your lab resources area. Learn more about how to do that here.
