Configure NixOS to allow Intel and Nvidia X.Org drivers coexist together (only needed because NixOS forces LD_LIBRARY_PATH variable propagation), and also to disable nvidia card by default. | '''1.'''

* Pros: better performance, Vulkan is supported. CUDA and OpenCL should work, though CUDA needs an additional device creation rule https://github.com/NixOS/nixpkgs/blob/05e375d7103ac51e2da917965c37246c99f1ae4f/nixos/modules/hardware/video/nvidia.nix#L72 | * Pros: better performance, Vulkan is supported.

The [https://github.com/guibou/nixGL nixGL project] provides wrapper to use GL drivers outside of NixOS. | * GL drivers on non-NixOS: The [https://github.com/guibou/nixGL nixGL project] provides wrapper to use GL drivers outside of NixOS. You need to have nvidia drivers installed on your distro (for kernel modules). Then supply nvidia driver version you use on host system to nixGL. | ||
* [https://github.com/dukzcry/crap/tree/master/primerun Optimus only]. Primerun will build nvidia kernel modules against your currently running kernel. | |||
