Describe the bug I don t have the backlight of the keyboard and the brightnessctl/power managment of xfce don t work anymore

To Reproduce Steps to reproduce the behavior:

1. Install a clean debian 11 system (I'm on debian 12 but i build heads on debian 11 on another computer)
2. Go to https://github.com/linuxboot/heads
3. Click on clone the repo, install the required packages
4. make BOARD=nitropad-nv41
5. update heads firmware with the just built binary
6. reboot system, remake htop-totp configuration, boot on debian 12 + xfce
7. The power managment plugin is not available, the keyboard backlight is off without possibility to turn on

Expected behavior When I press 'FN + F4" The backlight of the keyboard should increase. The power managment should work

Additional context I can t switch the backlight of the keyboard even by cmdline. The screen brightness though, work by "xrandr --output eDP-1 --brightness" so it s rather an issue of battery/power managment on this side Probably linked to this issue
