negative.code:         be the only driver there.
  
          If this is enabled, then the bus IDs of the NVIDIA and Intel GPUs have to be
          specified (<option>hardware.nvidia.prime.nvidiaBusId</option> and
          <option>hardware.nvidia.prime.intelBusId</option>).
  
          If you enable this, you may want to also enable kernel modesetting for the
          NVIDIA driver (<option>hardware.nvidia.modesetting.enable</option>) in order
