switcherooctl [options] [command]

switcherooctl is the command-line interface for switcheroo-control, a daemon that manages hybrid graphics on Linux laptops with multiple GPUs. It provides a simple way to list available graphics adapters and launch applications on a specific GPU.
On hybrid graphics systems with both integrated (power-efficient) and discrete (high-performance) GPUs, applications default to the integrated GPU. Using switcherooctl, you can run specific applications on the discrete GPU for better graphics performance.
The underlying daemon interfaces with the kernel's vga_switcheroo subsystem and provides a D-Bus API that desktop environments like GNOME and KDE use for GUI-based GPU selection.
Setting the environment variable DRI_PRIME=1 achieves a similar effect for individual applications.

-g, --gpu index

GPU index to use for launch command.

Display help information.

Display version information.

list

List known GPUs with their indices and capabilities.

Launch application on discrete GPU (or specified GPU with -g).

Requires switcheroo-control.service to be running. Only works on systems with hybrid graphics (typically laptops with Intel/AMD integrated and Nvidia/AMD discrete GPUs). Detection may incorrectly identify GPUs in some configurations. Does not provide mux switching (for systems with hardware mux).

switcheroo-control was developed for the GNOME desktop to provide a user-friendly interface for hybrid graphics management on Linux. It abstracts the kernel's vga_switcheroo mechanism, allowing desktop environments to offer "Launch using Discrete Graphics" options in application menus.
