Extracted info from referenced documents: 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. ------------ https://negativo17.org/prime-optimus-laptops-and-multi-gpu-systems/ https://news.opensuse.org/2024/12/09/gpu-switching-game-changing/ For openSUSE on SkyLake with Nvidia dGPU + integrated Intel iGPU I followed this installation and setup guide SDB:NVIDIA Switcheroo Control https://en.opensuse.org/SDB:NVIDIA_Switcheroo_Control After installing the switcheroo-control package, it had to be enabled as a service and then reboot: systemctl enable switcheroo-control.service ------- According to its online help info switcherooctl version 2.6 switcherooctl help list Usage: switcherooctl list List the known GPUs. switcherooctl help launch Usage: switcherooctl launch [COMMAND…] Launch a command on a specific GPU.
