The non-NixOS OpenGL/gpu story is unfortunately tricky as it requires a binary matchup between a userspace library and the kernel driver—which on non-NixOS is unknown to the Nix package manager since it's being managed by whatever the host is. This is arguably a flaw in how Nvidia architected this, but it is what it is. The classical solution is nixGL [1], but this requires downloading special nixified versions of the libraries on every host system kernel change. An alternative option that I was involved in the development of is nix-gl-host [2],
which manipulates the LD_LIBRARY_PATH for a Nix executable to allow it to link patched versions of the host's own userspace GL libraries. [1]: https://github.com/nix-community/nixGL [2]: https://github.com/numtide/nix-gl-host |
