Asusctl

asusctl^AUR is a useful utility provided by Asus Linux. It helps with managing BIOS settings, RGB lighting, and more on ASUS, TUF, and ROG laptops.

Installation

Downloading

Installation can be done through both the AUR with asusctl^AUR or through Asus Linux's own repository. To install via the repository, which does not require an AUR helper, visit https://asus-linux.org/wiki/arch-guide/ and follow the instructions provided by the guide.

Some features may require a newer version of Linux, specifically 6.1 or newer. linux-g14^AUR supplies the patches required for these features on an older kernel but should not be used now as it is obsolete. linux-g14 is also available in the custom repository.

supergfxctl^AUR and rog-control-center^AUR provide respectively a Optimus-like software built around ASUS laptops and a control GUI for Asusctl. Supergfxctl does not require an ASUS laptop and rog-control-center is moderately buggy. These packages can also be downloaded from the custom repo.

Supergfxctl

ノート: Supergfxctl is not needed nor recommended if you are not using a laptop with support for PRIME

Supergfxctl is an Optimus software for Nvidia, and as such is incompatible with optimus-manager^AUR, bumblebee, and other softwares of a similar vein. It is recommended to completely remove previous X11 and modprobe configuration related to the Nvidia and integrated GPUs. To use the dedicated GPU, nvidia-prime is required. At least on laptops with MUX switch support, Supergfxctl cannot run the entire X or Wayland session through nvidia-prime on its own.

Enabling

Enable the following services -

• asusd.service for Asusctl
• power-profiles-daemon.service for setting charging limits via power-profiles-daemon
• supergfxd.service for Supergfxctl
• --user asusd-user.service for ANIME sequence support on certain laptops
• --user asus-notify.service for notification support about your laptop

Configuration

ノート: See https://asus-linux.org/asusctl/ for more configuration info.

Battery and BIOS

Battery and BIOS options can be set to certain values in /etc/asusd/asusd.conf. The battery charge limit can be set in bat_charge_limit and other supported BIOS options can be set to be fixed on boot as well. The battery charge limit should be between 20 and 100. These values need to be set here to apply automatically after a reboot.

Fan curves

Fan curves can be set in /etc/asusd/profile.conf. Quiet, Balanced, and Performance mode can be selected as power profiles if power-profiles-daemon is enabled.

Visual Effects

Aura lighting and the ANIME matrix can be configured via their respective configuration files in /etc/asusd.

Supergfxctl

Supergfxctl is configured at /etc/supergfxd.conf. VFIO can be enabled with the discrete GPU and the startup mode (Hybrid or Integrated) can be set as well.

Usage

Asusctl

Asusctl is used via the asusctl command. The command will generate help info when run by itself. Aura effects, fan curves, power profiles, ANIME settings, and BIOS settings can be configured through the command rog-control-center works for a GUI, but is rather buggy and sometimes does not correctly apply settings.

Common BIOS settings

These BIOS settings have appeared on several laptops.

• GPU MUX mode - For laptops with integrated MUX switches, asusctl bios -D <mode> can toggle the MUX switch after a reboot. 0 enables it, and 1 disables it and switches it back to normal Optimus. asusctl bios -d gets the current mode.
• Device panel overdrive - For laptops with panels that support overdrive, asusctl bios -O <mode> toggles it. True toggles it on, and false toggles it off. asusctl bios -o gets the status of the feature.

Charge Limit

The charge limit can be set with asusctl -c <limit>, where limit is between 20 and 100.

Supergfxctl

Supergfxctl is run via supergfxctl. Using supergfxctl -m <mode switches between modes, and takes Hybrid or Integrated as options. It can also take Vfio if you enabled it in the settings.
