Recipes

The following recipes are generally applicable.

Install Debian

  • Debian 12 (Bookworm)
  • Include Gnome, Xfce

Install Nix and home-manager

  1. Install Nix package manager: https://nixos.org/download.html
  2. Enable experimental features in ~/.config/nix: 
    experimental-features = nix-command flakes
  3. Install home-manager as follows: 
    nix registry add flake:nixpkgs github:...       #(insert version pinned in global-config)
nix registry add flake:home-manager github:...  #(insert version pinned in global-config)
nix profile install home-manager

Install essential tools

  • sudo apt install python3 python3-fire
  • Install the newest Ansible version: Link

Apply automated config

  1. Clone the following repositories to some location, say ~/repos.
    • ~/repos/system-config (this repo)
    • ~/repos/system-config-priv (private repo)
      • Optional, needed for activation via --private. See details further down.
  2. Go to ~/repos/system-config/bin.
    • There is one script system_config.py with three commands.
      • store is used to store static dotfiles.
      • restore is used to restore static dotfiles.
      • activate_hm is used to activate an hm-config.
      • run_ansible is used to run an Ansible playbook.
      • activate is a shortcut to activate all three.
      • The flag --private requires the locally cloned system-config-priv repo.
    • Here are two representative examples with explanations.
      • system_config.py activate t470p-pub-only
        • Activate the public config for my Thinkpad T470p
        • This should work right out of the box, just by cloning this very repo.
      • system_config.py activate t470p --private
        • Activate the public+private config for my Thinkpad T470p
        • This option should only be available to me.
    • After running the hm config, the ~/.nix-profile/bin dir points to the installed software ("activated")

Configure shell and terminal emulator

  • Install oh-my-zsh, which will be placed automatically in ~/.oh-my-zsh. No further plugins needed.
  • Select /bin/zsh as standard shell using the chsh command
  • Configure colors in gnome-terminal

Configure display manager

  • Install lightdm
  • Run sudo dpkg-reconfigure lightdm
  • In config file /etc/lightdm/lightdm.conf, activate the line autologin-user=luk but be careful: It must be in the [Seat:*] section!

Install i3-with-nix

  • Normally, nix is activated in /etc/zsh/zshrc and /etc/bash/bash.bashrc
    • "Activation" means . '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
    • Problem: When i3 is started, nix is not yet activated, therefore nix-installed software is not in the PATH
    • Solution: Remove these activations
  • Instead, activate before starting the i3 session:
    • The script ~/bin/i3-with-nix is prepared to wrap the standard i3 session, along with an ativation account
    • Copy ~/bin/i3-with-nix to /usr/bin/i3-with-nix
    • Change file permissions to 655
    • Copy /usr/share/xsessions/i3.desktop to /usr/share/xsessions/i3-with-nix.desktop and replace in the file i3 by i3-with-nix

Setup locales

  • Run sudo dpkg-reconfigure locales with
  • en-US_UTF8
  • de-DE_UTF8

Configure alternatives system

  • Set default browser: 
    sudo update-alternatives \
--install /usr/bin/x-www-browser x-www-browser firefox 210`

Configure Brother HL-L2370DN printer

  • Install "Driver Install Tool" from Brother website, Version 19.08.2021 (2.2.3-1), file is linux-brprinter-installer-2.2.3-1
  • After cartridge change, may need to delete printer on CUPS (http://localhost:631) and run linux-brprinter-installer-2.2.3-1 to install the printer again

Install further software from external sources

  • Signal Messenger
  • Threema
  • Google Chrome
  • Dropbox
  • Docker (add group "docker" to user)
  • Xournal++
  • Veracrypt
  • Node.js
