A simple Electron Kiosk app that acts as a fullscreen browser to be used on Ubuntu Core 20 systems with the ubuntu-frame display server.
Install an Ubuntu Core 20 image on your device and configure network and user, so you can ssh into the system.
First install ubuntu-frame with
snap install ubuntu-frame
Now install this snap with
snap install electron-kiosk-wayland
To quieten log spam please connect the interfaces below
snap connect electron-kiosk-wayland:hardware-observe
snap connect electron-kiosk-wayland:process-control
The app comes with a configuarble url option that allows you to pick which page is shown. To use this feature simply call
snap set electron-kiosk-wayland url=https://www.ubuntu.com
The app will restart with the new URL
To make use of audio playback on your Ubuntu Core 20 Kiosk you
need to install the pulseaudio snap (currently it requires the version
from the beta channel, since only this provides the audio-playback
interface
snap install --beta pulseaudio
Now connect the app to the audio-playback slot pulseaudio provides
snap connect electron-kiosk-wayland:audio-playback pulseaudio
And restart it with
snap restart electron-kiosk-wayland
Audio playback should work seamlessly now. To adjust the volume you can use the shipped pactl command when logged in via ssh
sudo pulseaudio.pactl set-sink-volume @DEFAULT_SINK@ +10%
Raises the volume by 10%
sudo pulseaudio.pactl set-sink-volume @DEFAULT_SINK@ -10%
Lowers it by 10% To set it to an exact value you use
sudo pulseaudio.pactl set-sink-volume @DEFAULT_SINK@ 50%
Just clone this tree, make sure to have snapcraft installed, cd into
the cloned tree and just run
snapcraft
This will produce a snap package that you can install with the --dangerous
option of the snap install command.
