I don’t think apple gets enough credit for how good their automatic graphics switching implementation was. I’d argue that most users who benefitted from it didn’t even know it was happening. It’s such a useful feature too, because dGPUs generally kill notebook batteries, and even at idle, they probably generate an impactful amount of heat.

Is there truly no equivalent to apples automatic graphic switching for PC laptops? If so that’s WILD.

AMD and NVidia now use the same standard, which is PRIME for handoff and automatic shutdown using Runtime PM, and if needed muxes are handled by the vga-switcheroo.

On the latest NVidia/AMD hardware, no configuration should be required, unless you try to use Wayland on NVidia.

Unfortunately on NVidia you really need the latest hardware, both on the GPU and CPU side. If you do, it should generally "just work". Of course Linux is Linux and it might not.
