There are an almost ridiculous number of Windows-style desktops on Linux – and mostly this applies to the BSDs, too. Most of them are implemented in C, and most use various versions of the Gtk toolkit for their widgets: menus, dialog boxes, buttons and so on.
In approximate age order, the ones still being maintained today are Xfce; MATE, which is a fork of GNOME 2; LXDE; Linux Mint's Cinnamon; and Budgie, implemented in the GNOME-centric Vala language. //
Now we're up to 23. We could dig deeper, but we hope that we've made the point by now. There are several different languages here (but a lot fewer than 23 of them), and several different graphical toolkits (but again, well under 20). This is a vast amount of effort spent reinventing, and then maintaining, the basic concept of a round thing on the end of an axle.
But the underlying concept here is really quite a simple one. The window managers can't match the functionality of the Windows 95 Explorer, and not one of the desktops captures the simple elegance of the original. Windows 95 let you put the taskbar on any screen edge, but you only got one, and you couldn't change its length, or re-arrange or resize its contents, let alone change their orientation. Multiple rows was your only option. //
Remember the Basics of the Unix Philosophy:
Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.
That 1995 design was simple. The components of the desktop – the task bar, the file manager, the text editor, and so on – don't need to exchange lots of rich, complex messages. //
Nearly two dozen different Windows-like UIs represents a titanic waste of programmer effort, skill, and time. Hundreds, maybe thousands of people, working hard for decades… but all on different projects, meaning that none of them achieve greatness. For an example, look at KDE Plasma's 36 launcher menus.
It is 27 years since the first release of KDE, and I suspect that Microsoft has been laughing all the way to the bank ever since. The FOSS world can do better, and it's time it started to try. ®
