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.

Run:

user $xrandr --listproviders

Providers: number : 2
Provider 0: id: 0x6e cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 0 name:Intel
