Activate RGB Debian version
Activate RGB Debian version
Usually the RGB keyboard activates the backlight when you press the scroll wheel, but it doesn’t work on Linux. I’ve tried using xset commands.
Several aspects of this matter are handled through software and need particular drivers. More details about the problem will help someone assist you better. When the backlight functioned, but then ceased, knowing your hardware and the Linux version you're running will be beneficial to begin. I just noticed the post title mentions "Debian," which is a mistake. Updated by paex on February 16, 2025.
There are multiple xset instructions for controlling the keyboard lights: one sets them active, another disables them.
