envycontrol
GPU switching utility for Nvidia Optimus laptops
TLDR
SYNOPSIS
envycontrol [options]
DESCRIPTION
envycontrol is a GPU switching utility specifically designed for Nvidia Optimus laptops running Linux. It provides a streamlined interface for switching between integrated Intel/AMD graphics, hybrid mode (both GPUs active), and dedicated Nvidia GPU mode without requiring manual configuration file editing.
The tool simplifies power management and performance tuning on dual-GPU systems by handling the complex configuration changes needed for GPU mode switching, including display manager setup and driver configuration. Changes require a system reboot to take effect as the underlying graphics stack must be reinitialized.
