Display Brightness keys on RaspiOS trixie without running the setup script

Darmur · February 12, 2026, 6:35pm

I finally got my Argon One Up, and i’m finalizing the initial setup, so far so good.

I don’t want to run the argon setup script, I prefer to set things manually.

I am running RaspiOS Trixie, with up-to-date packages

I have the battery status icon with a proper driver, I got it from this repo, it works very well

I also added the script for automatic shutdown if the lid is closed for more than 3 minutes, from this repo, it also works like a charm

argononeup.md

NOTE: I use [ArchLinux ARM][] with [sway][] wayland window manager and [pipewire][] for audio.

All of the functionality here works with **NO** need to run `argononeup.sh` script.

# First time setup

As a one time setup, update pi bootloader EEPROM configuration:

    sudo pacman -S rpi5-eeprom
    sudo rpi-eeprom-config -e

This file has been truncated. show original

What I have still missing are the display brightness keys (the volume/mute keys are already working)

I can increase/decrease the brightness with those commands, but I did not find a way to do so when pressing the FN + F2/F3

ddcutil --skip-ddc-checks --disable-dynamic-sleep --sleep-multiplier 0.1 setvcp 10 + 5

ddcutil --skip-ddc-checks --disable-dynamic-sleep --sleep-multiplier 0.1 setvcp 10 - 5

the tool “bindsym” used in the previous link does not exist on RaspiOS Trixie

any hint?

I just finished my battery tray icon and now I am working on the brightness–well, someone was faster than me on the battery icon. On the bright side I am working on the one up tray which will try to have everything there, including the brightness control and remembering your settings from the previous boot.

I will be following this thread as I also want as much info as possible about the Argon One Up.
