Disclaimer

This guide expects some previous knowledge about NixOS and its configuration system.

Please note that NixOS is not officially supported by this project, and any issues specific to it shall be reported on the nixpkgs GitHub page.

Requirement

Linux 6.19 or newer is recommended. To install the latest Linux, put this in your configuration file:

boot.kernelPackages = pkgs.linuxPackages_latest;

Installation

ROG Control Center is included in the asusctl module, so you only have to add to the configuration file:

services.asusd.enable = true;

Then rebuild your NixOS

Important

Power profiles: asusd manages platform profiles and CPU EPP settings itself via the ACPI platform_profile interface. Running an external power profiles daemon (such as power-profiles-daemon or tuned) alongside asusd can cause race conditions over /sys/firmware/acpi/platform_profile and CPU EPP preferences. You have two options:

1. Let asusd manage profiles and do not enable an external daemon (e.g. do not enable services.power-profiles-daemon).
2. Keep the external daemon and disable asusd’s profile management by setting the following to false in /etc/asusd/asusd.ron:

change_platform_profile_on_ac: false,
change_platform_profile_on_battery: false,
platform_profile_linked_epp: false,

A common way to switch profiles is binding the Fn+F5 key to asusctl profile next Available profiles vary by system, see asusctl profile list.

Graphics Switching

See GPU Switching for how to manage the dGPU and MUX.

Cardwire is also packaged in nixpkgs. Enable it with:

services.cardwired.enable = true;

Note

The services.cardwired.enable module is currently only available on nixpkgs unstable. It will be included in the 26.11 release.

For installation and usage instructions, refer to the documentation.
