Theming

• To change system-wide themes, you need to change the following:

gnome

1. desktops/gnome.nix - Change the imports at the bottom.
2. users/albert/gnome-conf.nix - Change the variables at the top.

neovim

1. home-manager/neovim.nix - Change the following:
   • plugins = with pkgs.vimPlugins - Add your theme under "Themes"
   • extraConfig - Change the colorscheme and AirlineTheme sections

hyprland

1. hosts/$HOSTNAME/home-manager/hyprland/hyprland-conf.nix - Change the WALLPAPER_DIR variable in ".config/hypr/start.sh".text
2. hosts/$HOSTNAME/home-manager/hyprland/hyprland-conf.nix - Change col.active_border and col.inactive_border in the general section.
3. home-manager/bash.nix - Update the sessionVariable variable GTK_THEME

waybar

1. hosts/$HOSTNAME/home-manager/hyprland/waybar-conf.nix - Update all relevant colors. Possibly make configs for colorschemes and import them.

swaylock

1. hosts/$HOSTNAME/home-manager/hyprland/swaylock-conf.nix - Update all relevant colors. Possibly make configs for colorschemes and import them.

kitty

1. home-manager/kitty.nix - Update the content of home.file.".config/kitty/theme.conf".text

Firefox

1. home-manager/firefox.nix - Change the entry under "# Theming"

btop

1. home-manager/btop.nix - Set color_theme

bash / powerline

1. home-manager/bash.nix - Set theme in programs.powerline-go.settings

neofetch

1. home-manager/neofetch.nix - Update the contents of home.file.".config/neofetch/config.conf".text

GPG Keys

1. Import the user private key: gpg import gpg/users/albert/privkey.asc
2. Mark it as trusted: gpg --edit-key albert@sysctl.io, then type trust, then 5
3. On each new machine, run nix-shell -p ssh-to-pgp --run "ssh-to-pgp -i /etc/ssh/ssh_host_rsa_key -o HOSTNAME.asc"
   • This will output the identifier you add to .sops.yaml
   • Move HOSTNAME.asc to keys/hosts/ and upload to git and rename accordingly.

Secrets

1. To edit a file: cd to /path/to/nix-files/ and run:
   • nix-shell -p sops --run "sops secrets/secret_file.yml"
   • New shell alias: sops secrets/secret_file.yml
2. When you add a new machine, you must update the secrets files encryption.
   • Run sops-update secrets/secrets.yaml and commit the change.

Lanzaboote / SecureBoot

• Instructions here - Link

1. Create your keys: sbctl create-keys
2. Verify your machine is ready for SecureBoot: sbctl verify - Everything except *-bzImage.efi are signed
3. Enter Secureboot Setup mode in your EFI Settings on the motherboard (F10)
   • Security -> SecureBoot -> Set to Enabled and "Reset to Setup Mode" and exit
4. Enroll the keys: sbctl enroll-keys --microsoft
   • If you wish, you can select --tpm-eventlog, but checksums will change later (ie, at a kernel rebuild)
5. Reboot and verify you are activated: bootctl status
