Oh cool, one this you'll want to check is if it's a MUXless or MUXed setup, MUXless being the physical laptop screen is wired directly to the iGPU and nothing else, and the dGPU isn't wired to anything, and MUXed is their both wired to the screen and something decides what GPU does what.

It's my understanding, NVIDIA or any GPU really, has vBIOS, this is firmware that exists within the GPU and is a basic VGA "Adapter", then when you load the nvidia driver, that actually loads the 'real' nvidia firmware into the card, it then runs that firmware. I'm not too sure, but I think this is how it usually works, could be different on Mobile Chips (MX150), so _maybe_ when nothing is loaded, it's already in a 'sort of' low power state? Apparently it's also possible to 'Power Off' the dGPU via ACPI calls (https://www.reddit.com/r/VFIO/comments/7d27sz/you_can_now_passthrough_your_dgpu_as_you_wish/dpvwka6/) Bumblebee is super old, there should be another way to disable it, surely. > How can you tell "it's there"? > Doing lspci -vvv, I can see the MX150 using the NVIDIA Driver, I tried catting that log, however it doesen't exist. > What I don't know is if rendering 3D to the screen would work within Qubes. > I'm also skeptical, it's sort of passing through 2 iGPUs, you've got the Intel iGPU in dom0, then the virtual `VGA compatible controller: Device 1234:1111 (rev 02)` card within domU. I can't see why it wouldn't work, you're just telling the kernel to offload 3D Rendering to the dGPU. > OT: On my new Qubes/gaming desktop I am upgrading > I'm also doing this, but I'm thinking the Fedora/KVM route, I have a feeling Xen might be harder to setup. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
