So I have both an igpu and dgpu, which means this should be easy, yeah?

Namely, Ryzen 9 7900 and RTX 4070ti.

But for the love of god I can’t get any installation working correctly with this combo OOB.

I’ve tried Nix. I’ve tried Arch. I’ve tried Garuda. I’ve tried Endeavour. I’ve tried Pop! OS.

I’ve also tried Proxmox, Truenas Scale, and Unraid, Smart OS, and others.

But there’s always something wrong with display.

    iGPU shares one monitor with the dGPU, but on different protocol, which from what I read online is supported.

    It only really needs output when I flick it open.

    So maybe it needs a KVM switch instead of trusting the monitors splits.

      It’s possible you need a dedicated KVM for swapping the input of the iGPU/dGPU shared monitor. If the dGPU is only getting passed through to a VM, I don’t believe it will initialize until the VM explicitly takes control of it.

      And I think vGPU passthrough is disabled on consumer Ada/Ampere architectures unless there’s been a crack developed for it since then?

      The turing architecture (RTX 20 series) is the only one I know of that has a crack/drivers available for it but I may be wrong/out of date on that info.
