Understanding the Issue

Before diving into the configuration steps, it’s important to understand why the keyboard backlight may not be functioning. Common reasons include:

Identifying the root cause is crucial for applying the correct solution.

Configuration Steps

Step 1: Check System Settings

First, ensure that the keyboard backlight is enabled in the system settings:

1. Open the “Settings” application from the application menu.
2. Navigate to the “Keyboard” section.
3. Look for the “keyboard backlight” option and ensure it is turned on.

Step 2: Update System Packages

Outdated packages can lead to functionality issues. Update your system to ensure all components are current:

Step 3: Install Required Drivers

Ensure that the necessary drivers for your system76 hardware are installed:
