Setting Up a Public Kiosk in Ubuntu MATE 16.04: A Comprehensive Guide

Creating a public kiosk using Ubuntu MATE 16.04 is a practical solution for many environments, whether for libraries, schools, or even exhibitions. A public kiosk provides internet access, information dissemination, and an interactive experience for users. In this guide, we’ll explore the steps to achieve this setup, including configurations, security measures, and some customization options to enhance user experience.

Understanding the Public Kiosk Concept

Before diving into the technicalities, it’s essential to have a clear understanding of what a public kiosk entails. Typically designed for ease of use and security, public kiosks allow users to access pre-selected resources without exposing the underlying operating system to unnecessary risks. These kiosks usually run a web browser or specialized software to provide information or services, and administrators can control what functions users have access to.

Prerequisites for Installation

Before you begin, make sure you have the following:

• A computer or device: This will serve as your kiosk. It could be a standard desktop, a laptop, or even a dedicated kiosk machine.
• Ubuntu MATE 16.04 installation: Ensure your system runs this version or switch to a version that supports similar features.
• Basic knowledge of Linux: Familiarity with terminal commands and Ubuntu’s file system will help you navigate easily.

Step-by-Step Guide to Create a Public Kiosk

Step 1: Install Ubuntu MATE 16.04

If you haven’t done so yet, install Ubuntu MATE 16.04 on your kiosk device. You can download the ISO file from the official site. Use a USB stick or DVD to create a bootable installation medium and follow the installation prompts to set up your operating system.

Step 2: Update Your System

Once installed, it’s crucial to update your system to ensure you have the latest security patches and software updates. Open the terminal and execute the following commands:

bash
sudo apt-get update
sudo apt-get upgrade

Step 3: Create a New User Account

For kiosk purposes, you’ll want to create a non-administrative user account for everyday use. This will prevent users from accessing sensitive system settings and files. Use the following command to add a new user:

bash
sudo adduser kioskuser

You will be prompted to enter a password and some optional user information. Choose a strong password for security purposes.

Step 4: Install Kiosk Software

To provide users with a seamless browsing experience, you can use a browser like Mozilla Firefox or install a dedicated kiosk application like pimatic. For simpler configurations, you may wish to install a lightweight browser or even kiosk-specific software like kiosker.

To install Firefox, use the command:

bash
sudo apt-get install firefox

For kiosker, follow these steps:

1. Download kiosker from its official repository.
2. Follow the instructions in the README file or GitHub page to complete the installation.

Step 5: Configure the Kiosk Environment

Now, it’s crucial to lock down your kiosk environment. Start by setting up the kiosk user to automatically log in without requiring a password. Open the terminal and edit the LightDM configuration file:

bash
sudo nano /etc/lightdm/lightdm.conf

Within the file, you can add the following lines under the [SeatDefaults] section:

plaintext
autologin-user=kioskuser
autologin-user-timeout=0

This configuration ensures that whenever the unit is powered on or rebooted, it will automatically log in the kioskuser.

Step 6: Launch the Browser in Kiosk Mode

To start the browser in kiosk mode (a full-screen view without toolbars or menus), you can create a custom script that initiates the browser upon login. First, create a new file:

bash
nano /home/kioskuser/start_kiosk.sh

In this file, add the following lines:

bash

!/bin/bash

firefox –kiosk http://www.example.com

Replace http://www.example.com with your desired starting URL. After making the script executable, run:

bash
chmod +x /home/kioskuser/start_kiosk.sh

Step 7: Modify Startup Applications

To ensure that your script runs automatically when the kiosk user logs in, go to the desktop environment’s Startup Applications preferences. You can find this option in the MATE Control Center or the Main Menu under Preferences. Add a new entry, select your script, and save.

Step 8: Implement Security Measures

Security is critical in a public-facing kiosk. Here are some steps you can take:

• Disable keyboard shortcuts: Modify settings in your browser to prevent users from accessing shortcuts that exit Kiosk mode or return to the desktop environment.

• Restrict access to the terminal: You can make it more challenging for users to access the terminal by removing its entry from the applications menu.

• Implement a timeout feature: If your kiosk is idle for an extended period, set it to log out or return to the home screen. You can achieve this by scripting an idle watcher that triggers a logout command.

Testing Your Kiosk Functionality

Once everything is configured, it’s time to test the setup thoroughly. Log in as the kiosk user and check if the browser launches into full-screen mode as intended. Validate that website navigation works without accessing system internals. Furthermore, attempt to logout or access the terminal, ensuring that restrictions you set are effective.

Enhancements for User Experience

While your kiosk is functional, consider enhancing the user experience:

• Customizable Home Page: Depending on your audience, customize the landing page to include relevant links and resources.

• Feedback Mechanisms: Integrate a simple feedback form to collect user input about their experiences. This can be facilitated through Google Forms or a similar service.

• Digital Signage Features: Explore capabilities for digital signage, showcasing advertisements or important announcements to further utilize your kiosk.

Conclusion

Setting up a public kiosk with Ubuntu MATE 16.04 can significantly enhance information accessibility in public spaces. By following the steps outlined above, you can ensure a secure, user-friendly experience that meets the needs of your target audience. Regularly updating both the operating system and any web content displayed will keep your kiosk relevant and functional over time.
