How to Set Up Raspberry Pi in Kiosk Mode: A Complete Guide

Posted on by Lab

A Raspberry Pi in Kiosk Mode transforms your device into a single-purpose machine. Whether you’re building a digital signage system, an interactive information display, or a single-application setup, Kiosk Mode locks down the Raspberry Pi to display only the desired content. This guide will show you how to configure Kiosk Mode on a Raspberry Pi for seamless operation.

What is Raspberry Pi Kiosk Mode?

Kiosk Mode refers to a system configuration where the Raspberry Pi boots directly into a specific application or website, hiding all unnecessary UI elements. It ensures users can only interact with the intended interface, making it ideal for:

  • Digital Signage: Display advertisements, slideshows, or videos.
  • Interactive Kiosks: Run a web app or information display.
  • Single-App Environments: Lockdown the system to a specific application like a media player.

Why Use Raspberry Pi for Kiosk Mode?

  • Affordable Solution: Raspberry Pi offers a cost-effective alternative to commercial kiosk systems.
  • Customizable: Tailor the setup to display websites, apps, or multimedia content.
  • Compact and Energy Efficient: Small footprint and low power consumption.

What You’ll Need

  1. Raspberry Pi (Raspberry Pi 3, 4, or 5 for better performance).
  2. MicroSD Card with Raspberry Pi OS installed.
  3. Power Supply for Raspberry Pi.
  4. Monitor and HDMI Cable.
  5. Keyboard and Mouse (for setup only).

Step-by-Step Guide to Set Up Kiosk Mode

Step 1: Install Raspberry Pi OS

  1. Download Raspberry Pi OS Lite (for minimal resource usage) or Raspberry Pi OS Desktop.
  2. Flash the OS to a microSD card using Raspberry Pi Imager or Etcher.
  3. Boot the Raspberry Pi and complete the initial setup.

Step 2: Install Necessary Software

  1. Update the System:
    sudo apt update && sudo apt upgrade -y
  2. Install Chromium Browser:
    Chromium is commonly used for displaying web applications in Kiosk Mode.

    sudo apt install chromium-browser -y
  3. Install X Server (for Lite Version):
    If using Raspberry Pi OS Lite, you’ll need an X server:

    sudo apt install --no-install-recommends xserver-xorg x11-xserver-utils xinit openbox -y

Step 3: Configure Auto-Start for Kiosk Mode

  1. Create a Script to Launch Chromium in Kiosk Mode:
    nano ~/.xinitrc

    Add the following content:

    #!/bin/bash
xset s off # Disable screen saver
xset -dpms # Disable power management
xset s noblank # Prevent screen blanking
openbox-session & # Start Openbox window manager
chromium-browser --kiosk --noerrdialogs --disable-infobars --disable-session-crashed-bubble --disable-features=TranslateUI http://your-url-here

    Replace http://your-url-here with the website or app URL. Save and exit.

  2. Make the Script Executable:
    chmod +x ~/.xinitrc
  3. Set Up Auto-Login:
    Enable auto-login to avoid manual login at boot.

    sudo raspi-config
    • Navigate to System Options > Boot/Auto Login > Console Autologin.

Step 4: Enable Auto-Start of the GUI

  1. Edit the ~/.bash_profile file:
    nano ~/.bash_profile

    Add the following line at the end:

    startx

    Save and exit.

Step 5: Reboot and Test

Reboot the Raspberry Pi to verify that it launches into Kiosk Mode:

sudo reboot

You should see the specified website or app displayed fullscreen on the monitor.

Advanced Kiosk Mode Customization

Add a Virtual Keyboard (Optional):

For touchscreens, install a virtual keyboard:

sudo apt install matchbox-keyboard -y

Schedule Content Updates:

Use cron jobs to refresh or update displayed content periodically.

crontab -e

Add a job to restart the browser at specific intervals:

0 2 * * * pkill chromium-browser && chromium-browser --kiosk http://your-url-here

Hide Mouse Pointer:

Install unclutter to hide the mouse cursor:

sudo apt install unclutter -y

Use Omxplayer for Video-Only Kiosks:

For video loops, use Omxplayer to play files directly.

omxplayer --loop video.mp4

Troubleshooting Kiosk Mode

  1. Chromium Not Launching in Kiosk Mode:
    • Ensure the URL is correctly specified in the script.
    • Check for typos in the .xinitrc file.
  2. Screen Blanking Issues:
    • Double-check the xset commands in your script.
    • Disable blanking in /etc/xdg/openbox/autostart.
  3. Performance Problems:
    • Use a lighter Raspberry Pi OS version.
    • Disable unnecessary background processes.
