Bazzite Setup Guide

A friendly guide for setting up Bazzite on ASUS laptops

Newcomers should start by reading the Intro guide.

Bazzite is a gaming-oriented atomic Fedora image based on Universal Blue. Like other atomic Fedora images it uses rpm-ostree, and asusctl is not preinstalled. Bazzite ships Homebrew preconfigured, which is the supported way to install asusctl.

Installing Asusctl

The supported way on Bazzite is the ujust asus helper. It installs the Universal Blue Homebrew casks asusctl-linux and rog-control-center-linux from the ublue-os/tap tap, and enables the required services. No reboot is needed and the installation survives rebasing:

# <https://github.com/ublue-os/bazzite/blob/b798170d195f8466f687b61be1831c1ec785d942/system_files/desktop/shared/usr/share/ublue-os/just/82-bazzite-apps.just#L265-L405>
ujust asus

The services are enabled automatically.

Power profiles

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 disable the external daemon. Note that KDE Plasma’s PowerDevil can respawn power-profiles-daemon through DBus activation even after it is disabled, so be sure to mask it instead:

sudo systemctl mask --now power-profiles-daemon.service
# or, if you use tuned:
sudo systemctl mask --now tuned.service tuned-ppd.service

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.
