We have standards like pipewire, xdg portals and wayland in active development that try to cover anything a desktop OS might need. Lately there has been a huge push towards them, as the standards they replaced weren’t future proof at all.

But I take it that you are more concerned about fragmentation of these standards. I can almost guarantee that a lot if it will just whither away with time. Noone wants to maintain ancient protocols like X11 anymore. We might have another turbulent few years in this transition, but the end result will be worth it.

And I don’t get what you mean with compatibility exactly. There are lots of ways to define that, and the Linux desktop is excellent in many of them. We have xwayland for legacy applications, loads of translation layers to bring together older graphics APIs under the main vulkan drivers, WINE to run windows software, etc. You’re gonna have to be more specific there.

Who is this single person controlling all the desktop environments and window managers? Oo
