Subject: [Bug 117131] vga_switcheroo does not switch IGP -> DIS ( IGP == i915 , DIS == radeon )

No. The drivers are independent. vga_switcheroo provides the intermediary for
alerting the drivers when the user has switched the mux for muxed laptops. For
muxless laptops, the dGPU driver uses vga_switcheroo and ATPX to power down the
dGPU when it's not in use. The IGP driver is not involved in that.
