I don't quite understand the inner workings of nixGL, but with the help of an LLM I figured the issue is that this version detection

nixGL/nixGL.nix

Line 237 in b610529

versionMatch = builtins.match ".*Module ([0-9.]+) .*" data;

does not match what I have on my system:

[~/Development/nix-template] <main> * cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX Open Kernel Module for x86_64  590.48.01  Release Build  (root@)  
GCC version:  gcc version 15.2.1 20251112 (GCC)

#218 will fix this

[GamerBene19]

#218 will fix this

Thanks! Is there a workaround that I can use until that fix is merged and shipped in nixpkgs? I.e. is it possible to specify the version manually?

You should be able to change the url in your flake to my fork if you want (or make your own fork from mine).

# flake.nix
inputs = {
    nixgl = {
      url = "github:tom-ainc/nixgl"; # replace "tom-ainc" with "GamerBene19" if you want to use your own fork
      # ...
    };
    # ...
};

Just remember to change back to the this one when it gets fixed/they merge my PR -- I don't plan on keeping it up to date unless anything else happens to brick my dev environment lol.
