How do I configure brightness keys on my laptop running Bazzite? (sh.itjust.works)

Hey everyone, I’ve got Bazzite installed on my laptop and everything is working great so far. The only issue I’m running into is that the brightness function keys (increase/decrease screen brightness) aren’t doing anything.

Has anyone dealt with this? Any tips on how to properly configure or remap the brightness keys under Bazzite? I don't really know where to start and searching for info hasn't provided anything useful.

Thanks!

EDIT: the laptop is a Lenovo Ideapad 330-15ICH

Go to your settings panel and keyboard shortcuts. See if you can just bind them through there.

Thanks for the answer. When I try to bind the keys it doesn't recognize the keypress.

The brightness keys in this computer are Fn+F11 (bright down) and Fn+F12 (bright up), and when I go to Keyboard shortcuts/Energy/Screen brightness up (Crudely translated to english) the key is already there. The problem is that pressing those function keys the system doesn't recognize them.

Hrmm usually the media keys are without function key and the function key makes it the F number.

Have you tried it without pressing function key?

The laptop has Fs keys (F1, F2, F3...) and when you push and hold the "Fn" key those F1, F2, F3,... act as media keys. The thing is Bazzite does detect the push of the other combination (for example Fn+F1 which is mute) but it doesn't do anything when using the brightness key (for example "Fn+F11").

I don't know where to start to diagnose this.
