Hi everyone! I wanted to share a project I've been working on: Kawaiintu OS, a custom Linux distribution built from scratch.
If you've customized Linux recently, you know that modern desktop environments (specifically GTK4 and libadwaita) heavily restrict system-wide theme customization to maintain app stability and developer intent.
I wanted to bypass this limitation without breaking the system or relying on traditional CSS overrides.
🚀 The Technical Approach: Non-Destructive Hooking
Instead of modifying core system files, I took a different route.
I wrote a custom Python script that dynamically hooks into GTK 4.0 UI selectors.
- Real-time hue rotation: The script allows for dynamic hue rotation across 9 colors on the fly.
- Non-destructive: It doesn't permanently overwrite system themes. It injects the changes dynamically, keeping the base system clean and stable.
🛠️ Built from the Ground Up
I didn't use standard GUI remixing tools like Cubic. The entire ISO is packaged manually from the base system up. This includes:
- Custom GRUB bootloader
- Plymouth boot animation
- Seamless GDM (GNOME Display Manager) integration
This approach ensured a highly optimized and bloat-free footprint.

It’s been a fascinating journey pushing the boundaries of what's possible with modern Linux desktop environments. By combining the stability of an Ubuntu base with the flexibility of Python scripting, I was able to create something truly unique.
💻 Try it out
The project is completely open-source. I’d love for you to check out the code, try the OS, and let me know what you think about this dynamic hooking approach!

⚠️ Important Notice / 重要なお知らせ
Regarding Kawaiintu OS (Neo Moebuntu)
The concept and philosophical origins of this project respect the original Moebuntu by Mr. Toy. However, for any technical inquiries that Mr. Toy cannot answer—including the GTK4 Python dynamic color hooks, standalone theme architecture, and 2GB RAM footprint optimizations—I, the technical lead, will answer them.

Kawaiintu OS (Neo Moebuntu) について
本プロジェクトの思想的源流は、Toy氏のMoebuntuに最大限の敬意を払っています。 ただし、GTK4とPythonを用いた動的色相フック、スタンドアロンのTheme構造、および2GBメモリ環境でのシステム挙動など、Toy氏では回答不可能な「技術的仕様」に関するお問い合わせは、技術開発を担当した私宛にご連絡ください。
