If I understood correctly, bumblebee uses the intel graphics as the 'main' X server hardware, and another X server for the nVidia graphics, without a visible screen, and with VirtuGL to route GL operations to Pbuffer on that screen. I don't want all this setup. I want something much simpler: ignore the intel graphics completely, and use the nVida hardware with the nVidia driver. Does this laptop have a hardware LVDS mux? If yes, does someone know how to throw the switch via acpi_call?
