Set Full-Screen Boot Up

Experience the full-screen self-boot interface first. Please close the already open Home Assistant URL and run chromium-browser --start-fullscreen "http://localhost:8123".

If you want to automatically display the Home Assistant interface in full screen after booting, then do the following.

1. Go to the autostart folder

cd /home/pi/.config/autostart/


If the autostart folder does not exist, you need to create a new one.

sudo mkdir -p /home/pi/.config/autostart/

2. Create chrome_start_fullscreen.desktop file

sudo nano chrome_start_fullscreen.desktop

3. Edit the chrome_start_fullscreen.desktop file

[Desktop Entry]
Type = Application
Exec = chromium-browser --start-fullscreen "http://localhost:8123"

Save and exit: Ctrl+ X, Y, Enter.


If you want to cancel the full-screen self-start, comment out the contents of the .desktop file (by “#” )and restart the RaspberryPi.

cd /home/pi/.config/autostart/
sudo nano chrome_start_fullscreen.desktop

4. Exit full screen


Method 1: Press F11.

Method 2: Move the mouse to the upper column of the screen and click the exit button that appears.

Method 3: Right-click the pop-up menu, select “Exit full screen”.

Touch screen:

Long press the blank space to pop up the menu, click the exit button at the top of the screen or select “Exit full screen”.
