NixOS supports using NVIDIA GPUs for pure computing purposes, not just for graphics. For example, many users rely on NixOS for machine learning both locally and on cloud instances. These use cases are supported by the [https://github.com/orgs/NixOS/teams/cuda-maintainers @NixOS/cuda-maintainers team] on GitHub ([https://github.com/orgs/NixOS/projects/27 project board]). If you have an issue using your NVIDIA GPU for computing purposes [https://github.com/NixOS/nixpkgs/issues/new/choose open an issue] on GitHub and tag <code>@NixOS/cuda-maintainers</code>. | NixOS supports using NVIDIA GPUs for pure computing purposes, not just for graphics.
