Hybrid graphics

This page details the use of NVIDIA or AMD Switchable Graphics/Intel hybrid graphics.

When are hybrid graphics useful?

 * The display is connected to the iGPU.
 * There is no hardware multiplexer available (and therefore no BIOS option to switch to one of the cards)
 * NVIDIA or AMD cards and Intel SOC are the two graphic cards on the device.
