Configure, harden, and optimize your system in one command.
Click to collapse/expand
This is a post-installation automation script for Ubuntu, designed to apply my complete system setup in one shot — from hardening to theming, including essential software, configurations, and privacy fixes.
⚙️ Note: This script is still under active development — far from a final version. Many features and improvements are still to come. Use it as a solid starting point, but expect updates and expansions.
Originally developed on Ubuntu 23.10 (Mantic Minotaur), but also tested and running smoothly on Ubuntu 24.04 (Noble Numbat).
Since it relies on standard tools and GNOME GSettings, it should work on other Ubuntu or GNOME-based distributions — though official support and validation is currently for Ubuntu 23.10.
⚠️ If you use this script on other versions, feel free to report issues or submit corrections via pull requests.
- ⚙️ Fast, secure, and reproducible setup — focused on privacy, performance, minimalism.
- 🌑 Dark-themed, optimized GNOME desktop experience.
- 🔐 System hardening for personal/pro use: USBGuard, disable unused services, clean legacy tools.
- 🛠️ Full environment automation:
- ZSH + Oh My Zsh + Powerlevel10k.
- Essential plugins and aliases.
- GNOME and terminal customizations.
➡️ A fully optimized, secured, and ready-to-use Ubuntu system — with zero manual intervention.
Because I'm detail-oriented (some might say perfectionist, I prefer carefully crafted), everything must be set exactly as I want: Appearance, privacy, usability, security, and performance.
I built this script to ensure a reproducible, optimized, and efficient system, every time.
