The manifaturer/type of the primary system GPU.
Allows the correct GPU drivers to be loaded, potentially optimizing video output performance.
If you're on a hybrid system (intel/amd igpu + nvidia/amd dgpu) make sure to use
the hybrid options, only specifying the dgpu will not work properly.
Note that if using hybrid-nvidia, you will need to set `hardware.nvidia.prime.nvidiaBusId`
and `intelBusId` (or `amdgpuBusId`) to "PCI:x:y:z". To find the correct bus IDs, you can
use `sudo lshw -c display`. Note that you will need to convert the bus ID format from
hexadecimal to decimal, remove the padding (leading zeroes) and replace the dot with a
colon (so for example 0e:00.0 -> PCI:14:0:0).
