Issue/Bug Description:

Key combo does not work to adjust backlit

Files are in the correct place:

ls /sys/class/leds/system76::kbd_backlight/
brightness  brightness_hw_changed  color_center  color_extra  color_left  color_right  device  max_brightness  power  subsystem  trigger  uevent

Steps to reproduce (if you know):

Install either Pop 20.04 or Pop 22.04 and the backlit is not adjustable in either a live disk, after the install or after updates.

Expected behavior:

The key combos work and you can echo into the files in /sys/class/leds

We've got recent reports as system updates to 22.04 where it stops works. (ZD: 87844)

Does reverting https://github.com/pop-os/system76-dkms/pull/54 resolve the issue?

crawfxrd commented 3 months ago

And what is the firmware version?

2018-02-09 release has the note "Fixed keyboard backlight issues".

I got the bonw13 lab unit set up, and it's on 1.05.04RSA5-1, and the keyboard backlight isn't working. I'll try reverting that commit to see if it makes a difference.
