WangLu's Notes

I’ve been using Fedora Silverblue as my daily driver for a while now. Over time, I’ve fully adopted Flatpak, which I really enjoy using alongside Flatseal. I particularly appreciate how Flatpak gives each application its own isolated directory structure, making backups incredibly straightforward. However, I eventually hit a wall when it came to proprietary GPU drivers for workloads like media decoding, 3D rendering, and running local LLMs. In these scenarios, Flatpak’s runtime abstraction can sometimes become a liability. While this can sometimes be solved by enabling the Flathub repository or installing custom packages, I wanted to avoid that route. After comparing various alternatives, I decided to write my own lightweight application launcher. The Problem Flatpak achieves portability by bundling apps inside standardized runtime environments (like the Freedesktop or GNOME runtimes). While this solves the “dependency hell” of the 2000s, it introduces a subtle friction point for he...
