This Git repo describes how I setup the ASUS Zephyrus G14 (GA401IV) with Fedora 33 including a GNOME Shell extension to switch between GPUs and ROG profiles.

This also should work with the 2021 models as the new custom kernel is in here. Perhaps with them you need to boot the live media with nomodeset and remove this parameter after you installed the nvidia-driver.

1. Install Fedora 33

2. Boot to your installation, add Lukes Copr and update everything

dnf copr enable lukenukem/asus-linux
dnf update --refresh
dnf install asusctl

this also will install a custom kernel that helps with the 2021 G14 model to get suspend working

this also will fix the touchpad issues with all the G14 models that don't initialize correctly sometimes

asusctl helps with managing ROG power profiles and switching between graphics modes

3. Reboot

reboot

4. copy all the files to the appropriate directories

git clone https://github.com/hyphone/asus-g14-fedora.git
cd asus-g14-fedora
cp -R etc/* /etc/
cp -R usr/* /usr/
chmod a+x /usr/lib/systemd/system-sleep/asus_keyboard_backlight
systemd-hwdb update
udevadm trigger

we clone this repo

we go to the repo directory

we copy everything in this repo of etc to /etc/

we copy everything in this repo of usr to /usr/

we make the script /usr/sbin/asusboot and /usr/lib/systemd/system-sleep/asus_keyboard_backlight executable

mod the keyboard that page up / down is mapped to fn+up/down while home (pos1) / end is mapped to fn+left/right

you can use brightnessctl -d asus::kbd_backlight s +1 and brightnessctl -d asus::kbd_backlight s 1- and map this to a key of your choice in your DE

5. install some packages

dnf install --refresh kernel-devel akmod-nvidia xorg-x11-drv-nvidia-cuda akmod-acpi_call brightnessctl

akmod-nvidia and xorg-x11-drv-nvidia-cuda installs the Nvidia driver

kernel-devel is necesarry for the dynamic kernel modules to compile

acpi_call modules from the tlp repo is needed to make the custom fan control working

brightnessctl is used for controlling the keyboard backlight before and after suspend as there is a bug that the keyboard backlight sometimes does not switch completely off while suspending. I also use it to control the brightness with the keyboard as I'm overriding the default keys with page up / down.

6. Reboot

reboot

7. You can switch your prefered graphics mode via the GNOME Shell extension "asusctl-gex" or with "asusctl graphics -m (graphics mode)"

There is an example in etc/asusd/asusd_example.conf for how a custom fan curve should look like. I haven't named it asusd.conf so it does not override the defaults from asusctl and asusd.

Custom fan curves have a problem at least on the 2020 models that sometimes the fans start to pulsate and one has to suspend one or two times to bring them back to a normal state.

I also currently don't use custom fan curves because of this.

The main repo for the Gnome Shell extension can be found here: It is currently still in development when we find the time. In this repo here you find the most current version that I also use: .

Graphics Mode

• integrated - only use integrated AMD GPU while the NVIDIA is completely turned off
• hybrid - use the integrated AMD GPU as the main GPU. The NVIDIA can be used for offloading *1
• compute - use the integrated AMD GPU as the main GPU. The NVIDIA can be used for CUDA / OpenCL but not for offloading graphics.
• vfio - use the integrated AMD GPU as the main GPU. The NVIDIA can be used in combination with a VM for GPU passthrough.
• nvidia - use the dedicated NVIDIA GPU as the main GPU.

*1 to offload a graphics application to your NVIDIA you can use GNOME Shells feature via right click on an application icon and use run with dedicated graphics adapter

Profile

• Boost - high fan RPM, Ryzen Boost enabled
• Normal - silent fan until 49°C CPU temperature, spins up at higher temps, Ryzen Boost enabled
• Silent - silent fan until 69°C CPU temperature, spins up at higher temps, Ryzen Boost disabled

usually a reboot or a restart of Xorg is required to apply the changes. There will be a notification with a call to action to give you a hint what action is required. please note that the message sometimes is not correct when you switch multiple times without doing the appropriate action. So save your work and do as the asusctl and this extension tells you :)

silent is good for the integrated graphics mode. for every other graphics mode I recommend normal as the case would heat up too much on silent.

This extension uses asusctl to switch modes via asusctl's DBUS interface. You can either use the extension or asusctl directly if you don't use GNOME Shell.

If you don't have GNOME Shell but a desktop environment with a system tray I suggest you use this very handy application:

by Luke Jones (and his Kernel modules) are the key to this all. Without the efford of the community we wouldn't have such handy tools to control this machine. asusctl is used here to do most of the things, like graphics switching via the GNOME Shell extension or setting the ROG profiles.

You can use asusctl to switch your profile like so (use integrated, hybrid, compute or nvidia instead of {profile}):

asusctl graphics -m {profile}

You can also change the ROG profile via asusctl (use silent, normal or boost instead of {profile}):

asusctl profile {profile}

for more options have a look at this command:

asusctl --help

etc/asusd/asusd_example.conf

These are my custom fan curves for the asusd service from asus-linux.org. When on AC I usually use "normal" because of turbo is enabled with the default silent fan profile of the laptop. On "silent" I disabled turbo and I usually use this while on battery. This has a custom fan curve to make it silent.

etc/modules-load.d/...

• acpi_call.conf makes sure the acpi_call module is loaded (when installed) to get custom fan control working
