Target Milestone: ---
Classification: Fedora
Description of problem: Keyboard backlight worked until upgrading to FC34. The
Fn 5 key toggled the keyboard backlight on and off. In researching the new
method to expose the Fn keys to the user I found that there is no input/input5.
The input/input3 is configured.
