== Some things to keep in mind when setting up CUDA in NixOS == | |||
* Some GPUs, like Tesla K80, don't work with the latest drivers, so you must specify them in the option <code>hardware.nvidia.package</code> getting the value from your selected kernel, for example, <code>config.boot.kernelPackages.nvidia_x11_legacy470</code>. You can check which driver version your GPU supports by visiting the [https://www.nvidia.com/Download/index.aspx nvidia site] and checking the driver version. | |||
* Even with the drivers correctly installed, some software, like Blender, may not see the CUDA GPU. Make sure your system configuration has the option <code>hardware.opengl.enable</code> enabled. | |||
* By default, software packaged in source code form has CUDA support disabled, because of the unfree license. To solve this, you can enable builds with CUDA support with a nixpkgs wide configuration, or use binary packaged CUDA compatible software such as [https://github.com/edolstra/nix-warez/tree/master/blender blender-bin]. | |||
