Hello,
For now, you have to look at PCI ids. NVIDIA GPUs have "10de:xxxx" as
vendor/device ids, that's what is shown in your boxes on the right.
We should have better GPU support in the future. Right now, we only use
what Linux knows, and it knows pretty much nothing about NVIDIA GPUs
because of the closed-source driver :/
