Get started with Lumina for your Linux desktop

For a good number of years, there was a desktop operating system (OS) based on FreeBSD called PC-BSD. It was intended as an OS for general use, which was noteworthy because BSD development mostly focuses on servers. For most of its life, PC-BSD shipped with the KDE desktop by default, but the more KDE came to depend on Linux-specific technology, the more PC-BSD migrated away from it. PC-BSD became Trident, and its default desktop is Lumina, a collection of widgets written to use the same Qt toolkit that KDE is based upon, running on the Fluxbox window manager. You may find the Lumina desktop in your Linux distribution's software repository or in BSD's ports tree. If you install Lumina and you're already running another desktop, you may find yourself with redundant applications (two PDF readers, two file managers, and so on) because Lumina includes a few integrated applications. If you just want to try the Lumina desktop, you can install a Lumina-based BSD distribution in a virtual machine, such as GNOME Boxes.
