`nvidia-smi` shows that my driver version is 550.78. I ran `nixos-rebuild switch --upgrade` yesterday. My nixos channel is `nixos-unstable`.
Do you know something I don't? I'd love to be on the latest version.
I should have written my post better, it implies that 555 does not exist in nixpkgs, which I never meant. There's certainly a phrasing that captures what I'm seeing more accurately.
I did not mean to chastise you or anything, just to suggest you could be able to have a newer driver if you had missed the possibility.
The thing is, AFAIU, NVIDIA has several release channels for their Linux driver[1] and 555 is not (yet?) the "production" one, which is what NixOS defaults to (550 is). If you want a different degree of freshness for your NVIDIA driver, you need to say so explicitly[2]. The necessary incantation should be
This is somewhat similar to how you get a newer kernel by setting boot.kernelPackages to linuxPackages_latest, for example, if case you've ever done that.
I had this configuration but was lacking a flake update to move my nixpkgs forward despite the channel, which I can understand much better looking back.
Thanks for the additional info, this HM thread has helped me quite a bit.
