> The Switcheroo-Control is a D-Bus service to check the availability of
> hybrid GPU configurations and integrate with the desktop environment. This
> tool is the recommended solution to manage GPU switching on systems with
> multiple GPUs.
>
> Users are encouraged to move away from legacy tools like prime, bbswitch,
> and bumblebee, as they can cause more harm than good on modern systems.

> switcherooctl integrates well with Wayland and Xorg, is a lightweight
> userspace utility and its functionality extends across both Intel + NVIDIA
> and AMD + NVIDIA setups. By using switcherooctl, users can easily select
> which GPU to use for specific applications and eliminate the need for
> complex scripts or environment variables.

May be at opensuse forums someone already posted how to use it? I think
those forums will be best place to ask, due to user concentration.
