asusctl & ROG Control Center

COPR is Fedora’s official community package hosting platform (similar to AUR for Arch). The lukenukem COPR is maintained by Luke Jones (flukejones), the primary developer of asusctl itself — not a random third party.

The packages are GPG-signed (gpgcheck=1) and this is the officially recommended installation method by the asus-linux project.

Note: If you search for “lukenukem COPR” on Reddit, you may find threads raising concerns. These are typically about the openSUSE repository going temporarily offline — not a security issue with the COPR itself.

asusctl requires the power-profiles-daemon D-Bus API to manage performance profiles (Silent/Balanced/Performance). On Arch Linux, you simply install power-profiles-daemon and it works. On Fedora however, this conflicts with tuned, which replaced power-profiles-daemon as the default power management daemon since Fedora 41.

The solution is tuned-ppd, a Fedora-provided compatibility layer that exposes the power-profiles-daemon D-Bus interface while using tuned internally. This allows asusctl to manage profiles without removing tuned.

Note: The asus-linux project does not document this because it is a Fedora-specific issue. Their FAQ and ArchWiki page only state that power-profiles-daemon must be running.

If you have tuned installed (Fedora default), you must switch to tuned-ppd before installing asusctl, otherwise profile switching will not work.

asusctl needs the power-profiles-daemon D-Bus API. On Fedora 41+, tuned is the default and conflicts with power-profiles-daemon. Install tuned-ppd as the compatibility layer:

sudo dnf install tuned-ppd
sudo systemctl disable tuned.service
sudo systemctl enable --now tuned-ppd.service

tuned-ppd exposes the power-profiles-daemon D-Bus interface while using tuned profiles internally. asusctl talks to tuned-ppd as if it were power-profiles-daemon — no modifications needed.

Verify:

systemctl status tuned-ppd

Note: On Arch Linux, install power-profiles-daemon directly instead. This step is only needed on Fedora.

sudo dnf install asusctl asusctl-rog-gui supergfxctl

This installs:

• asusctl — main CLI daemon and client
• asusctl-rog-gui — ROG Control Center GUI
• supergfxctl — GPU mode switching daemon

sudo systemctl enable --now asusd.service
sudo systemctl enable supergfxd.service

Reboot to ensure all services start correctly:

sudo reboot

After reboot, verify asusctl detected your hardware correctly:

asusctl info

Expected output should include:

Product family: ROG Zephyrus G16
Board name: GA605WV

Useful utilities for monitoring hardware alongside asusctl:

sudo dnf install nvtop powertop s-tui lm_sensors i2c-tools

Limiting the charge to 80% significantly extends battery lifespan. The laptop runs normally on AC power regardless of this setting.

Set via CLI:

asusctl battery --charge-limit 80

Set via GUI: Open ROG Control Center (rog-control-center) → System Control → Battery Charge Limit.

Verify:

asusctl battery

This setting persists across reboots and is managed by asusd.

The Slash LED is the diagonal light bar on the lid of the G16. It supports multiple animations and can be configured to turn off on battery.

Show available animations:

asusctl slash --list

Available animations: Static, Bounce, Slash, Loading, BitStream, Transmission, Flow, Flux, Phantom, Spectrum, Hazard, Interfacing, Ramp, GameOver, Start, Buzzer

Recommended setup (AC only, off on battery and during sleep):

asusctl slash --enable -b false -s false

What these flags do:

• --enable — turn on the Slash LED
• -b false — disable on battery power
• -s false — disable during sleep

Set animation:

asusctl slash --mode Spectrum

Set brightness (0–255):

asusctl slash -l 128

asusctl provides three performance profiles that control CPU/GPU power limits and fan behavior:

Set a profile:

asusctl profile -P Balanced
asusctl profile -P Silent
asusctl profile -P Performance

Cycle through profiles:

asusctl profile --next

Check current profile:

asusctl profile

Note: Profile switching requires tuned-ppd to be running. See the installation steps above.

The GA605WV has a hybrid GPU setup: the AMD Radeon 890M (iGPU) drives the internal display, and the NVIDIA RTX 4060 (dGPU) handles GPU workloads.

supergfxctl manages which GPU mode is active:

Check current mode:

supergfxctl --mode

Switch mode:

supergfxctl --mode Hybrid
supergfxctl --mode Integrated

Note: Switching between Hybrid and Integrated requires a logout/login. Switching to AsusMuxDgpu requires a reboot.

Important: nvidia-powerd.service must remain disabled and masked on this laptop. It conflicts with AMD ATPX power management and causes soft lockups and reboot hangs (black screen, backlights stay on). Masking is essential because supergfxd directly calls systemctl start nvidia-powerd.service during GPU mode switches — disable alone does not prevent this. The mask (symlink to /dev/null) blocks both supergfxd and NVIDIA driver updates from re-enabling it. GPU power is managed via ATPX (via ACPI). See NVIDIA Driver Installation Guide for diagnosis details and commands.

Set keyboard backlight brightness (0–100):

asusctl led-brighter
asusctl led-dimmer

Open Aura configuration in ROG Control Center:

rog-control-center

Navigate to the “Keyboard Aura” section for animation, color, and per-key configuration.

Fan curves can be configured per performance profile in ROG Control Center or via CLI.

Open ROG Control Center:

rog-control-center

Navigate to “Fan Curves” to set temperature/speed curves per profile (Silent, Balanced, Performance).

CLI fan curve format:

# Show current fan curve data for a profile
asusctl fan-curve -m Balanced

# Set a custom curve (8 temperature/speed pairs: temp:speed,temp:speed,...)
asusctl fan-curve -m Balanced -D 30:0,40:10,50:30,60:50,70:70,80:85,90:100,100:100

Note: Fan curve customization requires the asus-armoury kernel driver. On kernel < 6.19, the driver is not available and curves set in the GUI may not persist as expected. See the Known Issues section below.

GPU monitor (AMD + NVIDIA):

nvtop

CPU frequency, temperature, load dashboard:

s-tui

Power consumption per process/device:

sudo powertop

Hardware temperatures:

sensors

Check asusd service logs:

sudo journalctl -b -u asusd

Check supergfxd service logs:

sudo journalctl -b -u supergfxd

Problem: ROG Control Center shows a warning that the asus-armoury kernel driver is not loaded. Some advanced features (PPT power limits, APU memory allocation, MUX switch control) are unavailable.

Cause: The asus-armoury driver was merged into the Linux mainline kernel in version 6.19. On kernel 6.18.x (current Fedora 43 default), the driver does not exist.

What still works without the driver:

• Fan curves (basic)
• Performance profiles (Silent / Balanced / Performance)
• Battery charge limit
• Slash LED
• Keyboard Aura / RGB
• GPU switching via supergfxctl

Solution: Wait for Fedora 43 to ship kernel 6.19 via dnf update. No manual action required.

After the kernel update, verify the driver loaded:

lsmod | grep asus_armoury

If it loads, reopen ROG Control Center — the warning should be gone and advanced features will be available.

Note on GA605WV support: The initial 6.19 release lists GA403-series models explicitly. If the GA605WV is not yet in the DMI table, some model-specific features (PPT tuning, APU memory) may still not appear even on 6.19. This is expected to be resolved via follow-up kernel patches.
