Configure Graphics Applications to Render Using the GPU Screen
To configure a graphics application to be offloaded to the NVIDIA GPU screen, set the environment variable NV_PRIME_RENDER_OFFLOAD to 1. If the graphics application uses Vulkan, that should be all that is needed. If the graphics application uses GLX, then also set the environment variable GLX_VENDOR_LIBRARY_NAME to nvidia, so that GLVND loads the NVIDIA GLX driver. NVIDIA's EGL implementation does not yet support PRIME render offload.
