VFIO
The GPUs being muxed makes this laptop great for PCI Passthrough.
Kernel parameters can be set to bind vfio-pci to the discrete GPU.
rd.driver.pre=vfio-pci nogpumanager vfio-pci.ids=1002:73ef,1002:ab28
The GPU can then later be unbound from vfio-pci and rebound to AMDGPU later without disturbing the X11 session.

Power Management
See Power management, Laptop#Power management, AMDGPU#Power profiles
Suspend
Attempting to use s2idle occasionally crashes AMDGPU, resulting in artifacting.
A legacy s3 patch is available. See Power management/Suspend and hibernate#Changing suspend method.~
Wireless
Wi-Fi
The MediaTek MT7922 works with the MT7921e driver, but has oddly high ping times (~20ms for a single hop) with high variability (>2ms jitter). So it is functional, but has problems.
Some have recommended switching it out for the more popular and widely supported Intel Wi-Fi cards.
ASUS Linux
The ASUS Linux stack provides users of this laptop with a great many ASUS specific functions, to name a few:
- Battery Charge Limit,
- Multiplexer (GPU) Controls,
- Panel Overdrive,
- Much more.
It is highly recommended to install these tools for the optimal experience on these laptops.
Issues
Seems to be mostly fixed as of 6.8.1. Some users still report occasional problems.
As of kernel 6.6.8, there are some issues on this laptop:
- Laptop will not resume from suspend and must be forcefully shutdown.
- Laptop will suddenly jump to 100% fan usage while on suspend and must be forcefully shutdown.
- Laptop will freeze after Gnome log-in and must be forcefully shutdown. After restarting, log-in works.
Some of these issues are stated to be solved as of 6.8rc5, but some still persist, so it is probably a good idea to stay on 6.6.7, at least until all of the issues are fixed.
downgradeAUR can be used to easily downgrade the kernel and add it to IgnorePkg automatically.
There is an issue open on the amd repo: https://gitlab.freedesktop.org/drm/amd/-/issues/3132#note_2293507.
