|
|
===================================
|
|
|
|
Inspired by: https://pimylifeup.com/ubuntu-chromium-kiosk/
|
|
|
|
Steps
|
|
-----
|
|
|
|
|
|
|
|
### 1.) Install Ubuntu Server (no desktop) on your computer than set hostname and timezone.
|
|
|
|
```sh
|
|
hostnamectl set-hostname check.local
|
|
timedatectl set-timezone Europe/Berlin
|
|
```
|
|
|
|
|
|
|
|
### 2.) Install minimal GUI and Tools.
|
|
|
|
```sh
|
|
apt install ubuntu-desktop-minimal
|
|
apt install language-pack-gnome-de
|
|
apt install xdotool
|
|
apt install dbus-x11
|
|
```
|
|
|
|
|
|
|
|
### 3.) Create a kiosk user with home-directory.
|
|
|
|
```sh
|
|
useradd -m kiosk
|
|
```
|
|
|
|
and disable Welocme-Screen
|
|
```sh
|
|
echo "yes" > /home/kiosk/.config/gnome-initial-setup-done
|
|
```
|
|
|
|
|
|
|
|
### 4.) Edit following file `nano /etc/gdm3/custom.conf` to turn of wayland and turn on autologin for user 'kiosk'.
|
|
|
|
```
|
|
[daemon]
|
|
# Uncomment the line below to force the login screen to use Xorg
|
|
#WaylandEnable=false
|
|
|
|
WaylandEnable=false
|
|
|
|
# Enabling automatic login
|
|
# AutomaticLoginEnable = true
|
|
# AutomaticLogin = user1
|
|
|
|
AutomaticLoginEnable = true
|
|
AutomaticLogin = kiosk
|
|
```
|
|
|
|
|
|
|
|
### 5.) Configure GUI of user kiosk to prevent monitor from sleeping
|
|
|
|
```sh
|
|
#gsettings list-recursively
|
|
|
|
# Does not work
|
|
#sudo -u kiosk gsettings set org.gnome.desktop.session idle-delay 0
|
|
|
|
# Set idle-delay from "uint32 300" to "uint32 0", needs 'apt install dbus-x11'
|
|
# You can check the value in "GUI-Session of kiosk -> Settings -> Power"
|
|
sudo -u kiosk dbus-launch dconf write /org/gnome/desktop/session/idle-delay "uint32 0"
|
|
```
|
|
|
|
|
|
|
|
### 6.) Create custom service to start firefox loading the page.
|
|
|
|
Therefore create a file `/etc/systemd/system/kiosk.service` with this content:
|
|
|
|
```
|
|
[Unit]
|
|
Description=Firefox Kiosk
|
|
Wants=graphical.target
|
|
After=graphical.target
|
|
|
|
[Service]
|
|
Environment=DISPLAY=:0
|
|
# Set firefox language, needs 'apt install language-pack-gnome-de'
|
|
Environment=LANG=de_DE.UTF-8
|
|
Type=simple
|
|
# Always a fresh firefox ('-' allow error if common does not exist)
|
|
ExecStartPre=-/usr/bin/rm -r /home/kiosk/snap/firefox/common
|
|
# Move Mouse (should also work on small screens), needs 'apt install dbus-x11'
|
|
ExecStartPre=/usr/bin/xdotool mousemove 4096 2160
|
|
# See: https://wiki.mozilla.org/Firefox/CommandLineOptions (just -kiosk URL => Start-Assistant, so use -url too)
|
|
ExecStart=/usr/bin/firefox -fullscreen -kiosk -url http://monitor.example.net/check.html
|
|
Restart=always
|
|
RestartSec=30
|
|
User=kiosk
|
|
Group=kiosk
|
|
|
|
[Install]
|
|
WantedBy=graphical.target
|
|
```
|
|
|
|
|
|
|
|
### 7.) Enable the service and reboot
|
|
|
|
```sh
|
|
systemctl enable kiosk
|
|
reboot
|
|
```
|
|
|
|
|
|
|
|
Troubleshouting

|
---------------
|
|
