How to make the Raspberry Pi display a web page fullscreen at power on

This short tutorial should be enough for you to be able to setup a Raspberry Pi with GUI mode and auto login enabled to disable a web page full screen automatically when it turns on.

Copy full-screen.sh into the home folder of the pi user, and run the following command: /home/pi/full-screen.sh

sudo chmod +x full-screen.sh

full-screen.sh

export DISPLAY=:0.0
xset s off
xset -dpms
xset s noblank
chromium-browser --noerrdialogs --kiosk https://google.co.uk --incognito

Create a folder called autorun inside the .config folder of the home folder of the pi user: /home/pi/.config/autorun/kiosk.desktop

cd /home/pi/.config mkdir autorun

kiosk.desktop

[Desktop Entry]
Type=Application
Exec=/home/pi/full-screen.sh
Hidden=false
X-GNOME-Autostart-enabled=true

Reboot the Raspberry Pi.
