📄 Description

This PR provides the capability to use the discrete GPU on a Multi-GPU System. That shall ensure best encoding and capabilities and performance for streaming.

To be able to use the dedicated GPU two environment variables must be set for wlroots. These are WLR_RENDER_DRM_DEVICE and WLR_DRM_DEVICES

The documentation of said variables can be found at their Repo

This connects to #20
