Linux on ASUS ROG Zephyrus G14
Overview
This page specifically about ASUS ROG Zephyrus G14, covering model GA401QM (2022 model?). May be applicable to others.
See also: https://asus-linux.org/wiki/fedora-guide/ -- The guide indicates many more problems than I had, I don't know if it is out of date or referencing other models.
Mine did not have the animatrix display.
Fedora Core 35
Dual Boot
This install may be done with Secure Boot enabled!
From original Windows (10 or 11) install, Start->Run->diskmgmt.msc and "Shrink volume" the C:, I shrunk it to ~230GB, leaving me with nearly 700GB Unallocated on my 1TB SSD.
From FC installer, select Automatic partitioning w/encryption.
This "Just Worked", except for a hiccup during first boot setup.
Important: when you reboot from Windows, make sure both GPUs are enabled ("iGPU mode off" in ASUS Crate Armory) or the NVIDIA one will not be visible to Linux. If you plan to wipe Windows completely, maybe consider this point carefully. Will update page if I find a way to enable the dGPU from Linux.
Wireless (WiFi)
MediaTek 7961 chip built into this machine, works great under FC35: no problems as of yet.
Sound
Sound worked out of the box, but on one random reboot was unavailable for unknown reasons. Repeated again one time after pressing the mute keycombo (Fn+F1). Fixed without reboot by killing pipewire/pipewire-pulse processes running as my own user (not the ones running as root.)
GPU
This is the sticky point of this machine; there are two GPUs (iGPU/AMD Cezanne, dGPU/NVIDIA GeForce RTX3060 Mobile) in a sort of hybrid config. The "nouveau" driver does not seem to enjoy this when both are enabled and visible: my kernel message buffer was full of crashes and stack traces while this was the case.
I installed the following drivers to combat this:
$ sudo dnf install akmod-nvidia xorg-x11-drv-nvidia-cuda xorg-x11-drv-nvidia-power
Disable Secure Boot: akmod-nvidia forces this requirement at this time, unfortunately.
To run programs using the dGPU for rendering, use a one-line script, like this, named something like "/usr/local/bin/nvgpu":
#!/bin/sh __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia "@"
To invoke it:
$ nvgpu origbinary --flags $ nvgpu minecraft --or-whatever

This adds Alt+F# to switch, Super+Alt+F# to move windows, then cleans up a few conflicting default bindings.
