After spending a full week trying to get Windows 10 running with QEMU+KVM on Garuda, which comes with Optimus Manager, I wrote a guide to share my discoveries. It's been a hell of a journey, but I did learn a lot about Linux!
My setup: Acer Helios 300, Intel Core i7-10750H, NVidia RTX 2060
Spoiler Alert: both the hardware (Optimus Muxless laptop) and the software (Optimus Manager) bring issues that compound on each other.
