What you’ll learn
In this tutorial we will create a snap of an X11 application to act as the graphical user interface for an IoT or kiosk device. For the introduction to this tutorial series and the Mir display server please visit here.
X11 is a legacy protocol, it is known to be insecure, so we need to take steps to ensure it is secured correctly. To do this we shall embed an intermediary X server based on Mir in the application snap and use snapd’s infrastructure to maintain security.
This tutorial assumes you are familiar with the material in Make a Wayland-native Kiosk snap. In particular, techniques for debugging problems in your snap are not repeated here.
What you’ll need
- An Ubuntu desktop running any current release of Ubuntu, or an Ubuntu Virtual Machine on another OS.
- A ‘Target Device’ from one of the following:
Using a Virtual Machine (VM) You don’t need to have a physical “Target Device”, you can follow the tutorial with Ubuntu Core in a VM. This guide shows you how to set up an Ubuntu Core VM.
Using Ubuntu Classic You don’t have to use Ubuntu Core, you can use also a “Target Device” with Ubuntu Classic. Read this guide to understand how to run kiosk snaps on your desktop, as the particular details won’t be repeated here.
