# My NixOS Config



Feel free to take a look around 🌷✨

## Essential Resources



### Nix



https://nixos.org/manual/nixos/stable/



https://nixos.org/manual/nixos/stable/options



https://nixos.org/manual/nixpkgs/stable/



https://nix.dev/manual/nix/2.18/



https://search.nixos.org



https://noogle.dev



https://nixos-and-flakes.thiscute.world



https://www.nixhub.io/



https://nixpk.gs/pr-tracker.html



https://lazamar.co.uk/nix-versions/



```

man configuration.nix

man home-configuration.nix

```



### Linux

## Installing NixOS



### Old Apple Hardware



The official NixOS installers don't include the necessary Broadcom wifi drivers so I have to build the installer myself with the drivers included:



```

nix build .#nixosConfigurations.installer.config.formats.install-iso

nix build .#nixosConfigurations.installer.config.formats.install-iso-gnome

nix build .#nixosConfigurations.installer.config.formats.install-iso-plasma

```



Then write I image to media with `pkgs.gnome.gnome-disk-utility` with "Restore Image". The image selector won't display symlinks so copy the nix store path of the result iso and press Ctrl+L to bring up the location bar and paste the path in.



Spam Alt+R while it's booting up to get to the firmware boot menu.



## Calamares



Always enable "Allow Unfree" so installing proprietary drivers doesn't crash the installation process.



Afterwards mount the new root partition and clone your nixos configuration repo:

```

cd /run/media//home/stel

git clone https://github.com/stelcodes/nixos-config

cd nixos-config

nixos-generate-config --show-hardware-config > hosts//hardware-configuration.nix

git add .

sudo nixos-rebuild switch --flake "/home/stel/nixos-config#"

```



Or you could croc the hardware configuration back to another computer:

```sh

ROOT="$1"

TEMPDIR="$(mktemp -d)"

if [ test -z "$ROOT" ]; then

  echo "Please provide a root path of the mounted NixOS installation."

  exit 1

fi

if ! [ test -d "$ROOT/etc/nixos" ]; then

  echo "The provided path doesn't seem to be the root of a NixOS installation"

fi

nixos-generate-config --root "$ROOT" --dir "$TEMPDIR"

croc "$TEMPDIR/hardware-configuration.nix"

```



## Writing Nix



### Avoiding having to pull in `flake-utils` in your flake

https://ayats.org/blog/no-flake-utils/

```nix

{

  outputs = {nixpkgs, ...}: let



    forAllSystems = function:

      nixpkgs.lib.genAttrs [

        "x86_64-linux"

        "aarch64-linux"

      ] (system: function nixpkgs.legacyPackages.${system});



  in {



    packages = forAllSystems (pkgs: {

      default = pkgs.callPackage ./package.nix {};

    });



    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {};

    overlays.default = final: prev: {};

  };

}

```



## Virtualisation



build vm image:

```

nixos-rebuild build-vm-with-bootloader --flake "$HOME/nixos-config#hostname"

```



test ssh:

```

QEMU_NET_OPTS='hostfwd=tcp::2222-:22' 

```



ssh into virtual machine by getting ip address (ip a) and `ssh @ip`.



build digital ocean droplet image:

```

nix build .#nixosConfigurations.hostname.config.formats.do

```



## Wayland



Use `QT_QPA_PLATFORM=xcb audacious` to see controls for adjusting plugin windows (Wayland QT issues)



## Music Production



### Wine + Yabridge



Run plugin installers with something like `wine plugin_installer.exe`.



Make sure yabridge knows about plugin paths:

```

# Common install locations

yabridge add ~/.wine/drive_c/Program Files/Common Files/VST3

yabridge sync

```



## Dconf



Values can be defined with Home Manager's `dconf.settings` option.



```

dconf dump /org/cinnamon/ | dconf2nix | nvim -R

pkgs.gnome.dconf-editor for GUI

```



## Messaging



My favorites:



```

XMPP: pkgs.gajim

Signal: pkgs.signal-desktop

```



## Obsidian



Might have to `rm -rf ~/.config/obsidian/GPUCache` after a major update.



## Phone tethering



For iphone hotspot tethering use `pkgs.libimobiledevice` and `services.usbmuxd.enable`.



## Gaming



### Standalone games



Probably going to run into openGL issues:

```

error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

```



One solution is to use distrobox:

```

distrobox create -n gamebox -i registry.fedoraproject.org/fedora-toolbox:38

distrbox enter gamebox

sudo dnf install opengl-games-utils

./run-game.sh

```



Another might be to use https://github.com/nix-community/nixGL but there will probably still be missing other libraries like wayland related stuff.



## Hardware



### GPUS



#### AMD

I have one of these: https://en.wikipedia.org/wiki/Radeon_RX_5000_series



### Wireless Controllers



The Xbox One controllers models 1708 and 1797 are some of best wireless controllers for linux. The package that provides their firmware is called xpadneo.

### Emulators

## Media



https://nixos.wiki/wiki/Kodi



My preferred setup:

```

Services -> Weather -> Gismeteo

Interface -> Skin -> Colors -> Concrete

Media -> Library -> Update library on startup

Media -> Music -> Show Song and Album Artists -> False

Media -> Music -> Split Albums into Discs -> False

Media -> Music -> Default provider for albums -> Local Only

Media -> Music -> Default provider for artists -> Local Only

Media -> Music -> Visualisations -> On

Player -> Music -> Visualisation -> Goom

```

This music sources don't purge missing tracks even when cleaned so you have to remove .kodi/userdata/Database/MyMusic.db all the time. Seems fixable? 🤔



## Compatibility



`pkgs.appimage-run`

        xserver = {

          autorun = true;

          desktopManager.plasma5 = {

            enable = true;

            # useQtScaling = true;

          };

        };

      };

    };

  };

}

```

### Btrfs RAID1 mirror



You need a btrfs volume and an unpartitioned disk to add to the volume. Mount the btrfs volume (let's say at `/mnt/archive`). The second disk should be unformatted (let's say it's `/dev/sdc`).



```sh

# Use the -f (force) flag if second disk has a partition table or partitions

# This will erase /dev/sda

sudo btrfs device add /dev/sda /mnt/archive

# Start converting the volume into a mirrored array for both the data and metadata

# This might take a LONG time depending on how much data is already present on the first disk

sudo btrfs balance start -mconvert=raid1 -dconvert=raid1 /mnt/archive

```

### Folding

Sometimes I forget how to fold in Vim. Here's the easiest way for me to remember:



- Fold: z prefix (the "z" looks like a folded piece of paper, if you look at it from the side)

- Fold MORE: zm, zM to fold everything

- Fold REDUCE: zr, zR to fold nothing

Need to add user with `smbpasswd -a my_user` manually
