[SOLVED] Is it me or is it my keyboard? WEV problem

z00k4 · 2025-06-01 20:31:05

Hello everyone.
I am a newcomer to ArchLinux, and I have been having a blast. That said, I have a nagging problem. The strangest thing truly.
Context: I am trying to set up brightness control on my desktop PC monitor, (Arch + Hyprland) using the keybinds in hyperland.conf. To check for the correct key, I use wev.
But here is the problem:
- I use wev; I press F1 and F2 and they register respectively as

XF86MonBrightnessDown, code:232

and

XF86MonBrightnessup, code:233

. I notice that no other F key registers, unless I press Fn beforehand. Then if I bind F1 and F2 (with their relative code) in hyprland.conf, they don't work AND they stop registering in wev. - But then, in a strange plot twist, F5 and F6 start to register, with

XF86KbdBrightnessDown, code:237

and

Xf86KbdBrightnessUp, code:238

respectively (I notice the difference between "Mon" and "Kbd"). So, I bind F5 and F6, write hyprland.conf and....
- None of the four F Keys mentioned now register in wev.

I am stumped. I looked around in the wiki and googled all afternoon, but I cannot find a solution. I even used two guides, relying on bash scripts, to no avail
(here they are: https://albert.nz/hyprland-brightness and https://flarexes.com/hyprland-getting-s … n-and-more).

You should know that, for some reason, on Windows (I am dual booting), the F keys work normally, while on Arch, they only work in tandem with Fn and produce no effect when pressed alone. Other important info:
- I have the brightnessctl package installed
- The problem was there even before trying to bind them in hyprland.conf

EDIT: after some more googling, I discovered that the keys are ALL registered if I press them after

sudo libinput debug-events

. The only thing is that they are registered as media keys unless I press Fn before (I kinda hate it tbh, but oh well). Still, the problem persists.

What am I missing? The keyboard is an EPOMAKER FekkerXGalaxy80. Is it just not compatible? I have no other keyboard available at the moment, what should I do?

Thanks to anyone that cares to give advice.

1. you'll have to bind those action keys to some action w/ your hyprland config (eg. brightnessctl commands, simply installing that package won't do anything)
2. Seems your keyboard (that is not spelled this way) uses apple_hid, https://www.reddit.com/r/Epomaker/comme … _in_linux/

I did bind the actions in hyprland.conf, sorry for not being clear. Thank you for the suggestions, I will try now and report back.

It works! Thank you a lot. I will mark the thread as closed, but what is this hid_apple option about?
