I recently built a computer for my dad who wants to get into local llms.
I wanted to write this post so that if I have to fix his computer, I have a reference of how I configured it. Also this was a great excuse opportunity to learn about nix. If the experience is good, I might migrate from Fedora.
Stick around to see my updates
why nix?
My initial plan was to use Nobara, as I use it on my HTPC and has a pretty painless installation and if my dad wanted to play games it would be relatively straightforward for him.
I was thinking of using nix as the package manager for ollama, vscodium and ROCm, so that way if he needs to reset the computer, it should be relatively easy to get back to work. However, I couldnât find anyone online who did this kind of setup.
My main hesitation with NixOS was that the OS and packages wouldnât get as many updates as bleeding edge distros and it would lead to potential issues with hardware updates. As I did more research this was not the case. Specifically at 0:52 in No Boilerplateâs video where he talks about how Nix has the most number of new packages
Also his story at 2:00 is the same experience I had with arch and fedora, where a update borked my desktop manager
I edited my configuration.nix to include the following
let
home-manager = builtins.fetchTarball https://github.com/nix-community/home-manager/archive/release-24.11.tar.gz;
in
{
imports =
[
./hardware-configuration.nix
(import "${home-manager}/nixos")
];
users.users.eve.isNormalUser = true;
home-manager.users.eve = { pkgs, ... }: {
home.packages = [ pkgs.atool pkgs.httpie ];
programs.bash.enable = true;
# The state version is required and should stay at the version you
# originally installed.
home.stateVersion = "24.11";
};
neovim
I wanted to set the default text editor to neovim
copying text from neovim to the rest of the system
while writing this guide I wanted to copy the text from neovim to the system keyboard
I added the following entries to my configuration.nix following the OPâs post
This is great, but there are too many configurations + repo structures.
Iâm going to follow this guide because they have a video of getting a repo setup
following the video guide
changes from flakes guide
add nix.settings.experimental-features = [ "nix-command" "flakes"]; to configuration.nix
I have been using nixos for about 6 months now and I think it is awesome. I have found that my favorite flake thing is Snowfall lib. I am happy to help if you have any specific questions.
The way I went about organizing stuff is to have a set of modules for NixOS and Home Manager that I keep in a public repo, but have all my host configs in a private repo (so as to hopefully not leak stuff like domains and IP address layouts lol). Also I have another separate repo for secrets using sops-nix.
Anyway happy to see more people get into NixOS, as I think itâs pretty great.
interesting. I took a look at snowflake. Can you explain why you use snowfall flake over others.
Does it automatically create the folders within the modules?
I am most familiar with python environments, so if thereâs something that can declaratively add packages using the cli (ie if I do uv add pandas my pyproject.toml file gets pandas appended to the dependency) similar to uv or poetry. I would use that.
I want a package where if I run a command package-manager add package, package gets added to my nix environment or the flake file
So, there are a lot of things that do similar stuff for flakes - flake-utils, flakelight, haumeaâŚI just found snowflake first and continue to think that it removes enough boilerplate to be worth using. It does want a specific filesystem layout, but that actually works for me. Youâll find that there are a ton of different ways to do things in NixOS and as a result thereâs a lot of personality in every config.
Nope, but it does import everything for you automagically which tends to clean up imports a good amount.
I donât think I have seen anything specifically which does this. I think generally you want to have that stuff be different enough for hosts/users that itâs not worth it to have a global add like that. Plus a lot of times thereâs not a single place you would put that kinda stuff - for example my config has each host in its own directory, and sometimes even in different files in that directory which are imported into default.nix.
As an example, my main workstation config is in nixos-snowzen/systems/x86-64-linux/titan/ which has the following config files in it: default.nix, hardware-configuration.nix, networking.nix, stylix.nix, and users.nix. These could in theory all just be in default.nix as that is the only required file, but I like splitting it up. The system itself really only has a few packages that are installed globally - things I want if somehow my user gets messed up: vim, git, wget, bash. It also defines a bunch of stuff at the system level - what services I want enabled at the system level like AMD GPU stuff, lm-sensors, bluetooth, zfs, podman, xwindows config (though my actual GUI config files live with my user) including display resolution, VRR & DPI settings. This is also where I configure rocm, ollama, etc.
Most of that stuff is actually in my zen config modules in my zenix-modules repo which I linked in my last post. The config for each thing is defined there, and I just enable/disable/customize in the system config with something like:
# since zenix is in a different flake from my system config, zenix modules do need to be imported:
imports = [
...
inputs.zenix.nixosModules.zenix
...
];
zen = {
system = {
zfs.enable = true;
podman.enable = true;
};
...
ai = {
rocm.enable = true;
ollama.enable = true;
ollama.host = "0.0.0.0";
};
...
};
To make this a bit more concrete as to what this actually does, you can see how each of these options is defined and what they actually configure here (zfs), here (podman), here (rocm), and here (ollama).
Obviously it has taken me quite a while to get to this point. My config did not come about over night, it has taken a lot of work. Even though itâs nowhere near perfect, I am pretty happy with it.
My users are configured pretty similarly, and they tend to just use a bunch of stuff from my zenix-modules for configuration, though there are a few tweaks and system/user-specific stuff configured outside of zenix.
Another tip is to check out awesome-nix which has a pretty good collection of tools you might find useful. Once you start using flakes, I have found that nh or nix helper is pretty rad and I use it instead of nixos-rebuild all the time now. The output is much nicer.
I am getting on a plane later today so I may or may not be able to reply until tomorrow, but I am looking forward to seeing your progress! NixOS is fun. I hope you enjoy your journey.
Yep! Thatâs how I started too. Once you decide if you like it and want to use NixOS on multiple computers, thatâs when frameworks like this really start to be useful. Especially when you start to want to break up configs and use chunks of them here and there.
I guess one other handy thing is being able to very easily use overlays when you want to use packages from a different channel - for example when most of your config is using a release (say 25.05 soon!) but you want some packages from unstable, Snowfall lib makes that very easy. But thatâs definitely a bit more advanced use-case - I only really use that for getting newer kernels and ollama-webui (the 24.11 version of that package doesnât support the âthinkingâŚâ stuff from models like deepseek-r1 but the unstable version does).
I was going to follow the video, but after watching it, I realized that Michaelâs config had already covered most of the content.
initial changes
standalone vs nix os module
Initially I was thinking of using the NixOS module as the video mentioned it would be easier to manage users at a system level, but some folks on the internet brought up 2 benefits that made me reconsider.
Standalone doesnât write a entry to the boot manager, so you frequently change the home configuration, your boot will get spammed
You can separate user space from system
Also when learning, it is much easier to follow someone elseâs guide and modify the instructions
I realized that my customizations had gone off both tutorial paths. Fortunately I had chatgpt to help explain how it works. I had it summarize the questions and answers using discourse
Chatgpt questions
Q1: How does Michaelâs config interact with Home Manager?
Q2: Why do I get a flake error about missing homeConfigurations?
Q3: How do I manage my dotfiles using Home Manager in Michaelâs setup?
Q4: How do I link my dotfiles directory in the repo with Home Manager?
Q5: Do I have to declare each dotfile in Home Manager explicitly?
Q6: What about relative paths if my home.nix is in a modules folder?
Q7: How can I add fish, fzf, and zoxide and share this configuration with a new user?
updates to neovim with home manager
I previously configured neovim this way, but now that I have michaelâs config, I need to update my files.
There are 2 crucial changes
Move neovim to home.nix within my modules folder
Enable auto/smart indent
updating home.nix
I started by removing neovim from my configuration.nix.
then I added a new entry within the programs section of home.nix. I did the same with librewolf
programs = {
# ...
neovim = {
enable = true;
viAlias = true;
vimAlias = true;
# Pass configuration options directly
extraConfig = ''
set autoindent
set smartindent
filetype plugin indent on
'';
# Optionally, include plugins using an overlay or package reference.
# For example, using vim-nix if itâs available as a package:
plugins = with pkgs.vimPlugins; [ vim-nix ];
};
configure my commit username and email, replace $email and $username with your github username and email
git config user.email "$email"
`git config user.name â$usernameâ
check for any changes using git status. The command will return any files that need to be commited
git status
git status
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
modules/file.nix
nothing added to commit but untracked files present (use "git add" to track)
add the files that you want to track. Replace $filepath-name with the relative path, so if you have a file named file.nix in the modules folder make sure to replace the $filepath-name with modules/file.nix
git add $filepath-name
write a commit message
`git commit -m âadded file.nix to trackingâ
keep track of your commits using git log. You can use git revert $hash, which is the text after
example output

commit db8a273b0f88bfb0e40291279dd887e5181aca5e (HEAD -> master)
Author: bedhedd <$user.email>
Date: Sun Apr 13 14:27:27 2025 -0500
fix fish prompt to install grc, it does not exist in 22.05
the db8a273b0f88bfb0e40291279dd887e5181aca5e is the structure of the commit hash,
if I needed to reset to this commit db8a273b0f88bfb0e40291279dd887e5181aca5e, I would run the command git reset db8a273b0f88bfb0e40291279dd887e5181aca5e
If I want to push these changes to online github, repository, I would run
git push origin master
origin refers to your local branch
master refers to your remote online github repository
when pushing to a remote online github repository, the name of the local branch must also be available on the online remote repository. You can check which branch you are on with git status
using fish as the default shell
adding fish to home manager and NixOS
michaelâs home.nix config has the following line section for bash, I want to change it so that fish is the default shell for all users
I initially tried to use chatgpt, to modify michaelâs config + the nix wiki documentation on fish. It worked in adding a entry to homemanager, but failed to get fish to autostart. https://nixos.wiki/wiki/Fish#Home_Manager
The nix wiki has the following for fish and home manager
Michaelâs config didnât had home manager configure it by the system, so I couldnât copy paste the wiki entry. Furthermore, I wanted fish at the system level. Finally I needed comment out grc from the plugins list because it didnât not exist in my NixOS version of 22.05
Doing some research and looking at the fish config, I realized that nix will autogenerate a config.fish file. the interactiveShellInit command will append any additional fish commands into. I followed a similar structure to michaelâs dotfiles structure, and created a fish-config.nix file in the dotfiles folder. This will be helpful later as I add zoxide.
I created a separate file because I knew that my config.fish will get long, and did not want to make my home manager too unreadable. My personal rule for moving scripts to dedicated files is if it is >5 lines and becomes harder to read, it deserves a dedicated file.
autostarting
When it came to autostarting, Chatgpt kept hallucinating, even with web search tool on the o3-mini-high and o3-mini it still failed. https://nixos.wiki/wiki/Fish
These are good instructions, but I didnât know how to get it working for my setup. I modified michaelâs entry to work for my setup. My rebuild command sudo nixos-rebuild switch --flake . failed to build because interactiveShellInit did not exist, I replaced it with initExtra. Ultimately this is what I used to have fish autostart
After adding zoxide and fzf to the packages, I added a entry to zoxide my programs section
programs = {
home-manager.enable = true;
direnv.enable = true;
# ... other program entries, zoxide below fish
zoxide = {
enable = true;
enableFishIntegration = true;
options = ["--cmd cd | source"];:
};
To make sure that fzf works with fish, I added the following entry to my fish config (dotfiles/fish-config.nix) based on the wikiâs fzf entry https://nixos.wiki/wiki/Fzf
function fish_user_key_bindings
if command -s fzf-share >/dev/null
source (fzf-share)/key-bindings.fish
end
fzf_key_bindings
end
if you want to keep it in interactiveShellInit as a string you can also do that as well
just to let you know, nixos.wiki is considered abandoned and will most likely be out of date. There is an ongoing official wiki effort at wiki.nixos.org, which forked off of the old wiki.
Blog posts usually end up being a pretty good shout as well, but be wary in copying them to the T, as stuff moves pretty fast, so your best bet is usually looking directly at the options section of search.nixos.org, or for home manager, home-manager-options.extranix.com

turns out my config in home manager programs was misconfigured
programs = {
home-manager.enable = true;
direnv.enable = true;
# ... other program entries, zoxide below fish
zoxide = {
enableFishIntegration= true;
options = ["--cmd cd fish | source"];
};
The correct configuration should be
programs = {
home-manager.enable = true;
direnv.enable = true;
# ... other program entries, zoxide below fish
zoxide = {
enable = true;
enableFishIntegration = true;
options = ["--cmd cd | source"];:
};
I ran a rebuild command and it fixed the issue. I have updated the op
However I couldnât use the <nixos-hardware/common/gpu/amd/default.nix> because I used flakes. With the help of chatgpt and websearch I was able to use the correct import of nixos-hardware.nixosModules.common-gpu-amd.
Before that, I tried nixos-hardware.nixosModules.gpu.amdgpu, but threw errors when I tried to rebuild.
sudo nixos-rebuild switch --flake .

I donât think you need to pull in common.amd.gpu directly, since itâs exposed as common-amd-gpu at the module top module level in default.nix which you linked somewhere in your post.
This is working on my AMD GPU systems, one of which is an AMD APU and the other of which has a 7900XTX - though caveat, both have xwindows instead of wayland and Iâm running older kernels. The newest kernel I am running anywhere is probably 6.12.19-xanmod.
Unfortunately some cursory searching through nixos options hasnât shown me anything about declaratively setting refresh rate in wayland, which you can do in x11 - at least you can pass through some options to the x11 config file to enable things like dynamic refresh rate.
What does wlr-randr say? In the past I have had to do wacky things with xrandr to get the correct resolution/refresh rate working in x11, though I have ironed that out with some extra configuration which unfortunately seems to be unavailable in wayland for reasons I donât have enough brains to comprehend.
