Lumina Desktop Environment
Lumina-DE is a lightweight, BSD licensed desktop environment designed specifically for use on FreeBSD (although it should be easily portable to other Unix-like OS's as well). Lumina is based on Qt 5 (without QML) and Fluxbox window manager.
The Lumina Desktop Environment is a lightweight system interface that is designed for use on any Unix-like operating system. It takes a plugin-based approach, allowing the entire interface to be assembled/arranged by each individual user as desired, with a system-wide default layout which was setup by the system administrator. This allows every system (or user session) to be designed to maximize the individual user’s productivity.
