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.[1]

Run:

user $xrandr --listproviders
