NixOS nVidia Driver Version Bounds

Question

I'm trying to get NixOS to work with my old GeForce 6600, which only accepts an nVidia driver version <305 (304.xx). Is there any way to put an upper bound on the kernel module version / proprietary version in my configuration.nix? Any help would be greatly appreciated!

Answer 1

You have to use nvidiaLegacy304 instead of nvidia in the system.xserver.videoDrivers = [ "nvidia..." ]; declaration (use hardware.opengl.videoDrivers for the unstable channel).
