Basically the title. I’ve only ever seen huge 20 page guides on how to make it work. Is there an easy way?

Specifically on Debian or Arch with a laptop with two gpus (zephyrus g14)

    I have the 2020 G14 and I got this working once. I’m afraid easy and simple are not a thing here, as you need to understand what you’re doing if you want it to work well. The basics are:

    • Prevent the host system from loading any drivers that touch the discrete GPU. This is done by attaching it to the VFIO driver and uninstalling/blacklisting the Nvidia and Nouveau drivers.
    • Make sure you have the correct kernel parameters to support virtualisation and PCI-e passthrough.
    • Create a Windows VM and attach the Nvidia GPU to it.
    • Setup Looking Glass so you can play with the best possible latency. This will likely require a dummy USB-C display stick.

    Personally, I don’t think it’s worth the hassle. I keep a Windows install for when it’s needed, and do most of my gaming on a separate system.
