What kinda issues are you having? Most of my problems with Nix are solved with overlays or creating a module. Admittedly, in order to do that you still have to know how to fix your issue the usual linux way. Afterall, Nix is more of an abstraction tool IMO; good for replicating something across a ton if devices. If you don’t need that, there’s other distros that work much better out of the box.
