Hello, yesterday I officially released Louvre v1.0.0, a C++ library designed for building Wayland compositors with a primary focus on ease of development. It provides a default method for handling protocols, input events, and rendering, which you can selectively and progressively override as required, allowing you to see a functional compositor from day 1.
It supports multi-GPU setups, multi-session (TTY switching), and offers various rendering options, including a scene and view system that automatically repaints only the damaged (changing) regions during a frame. Because it uses multiple threads, it can maintain a high FPS rate with v-sync enabled when rendering complex scenarios. In contrast, single-threaded compositors often experience a rapid drop in FPS, for example, from 60 to 30 fps, due to “dead times” while waiting for a screen vblank, leading to the skipping of frames.
The library is freely available, open source, thoroughly documented, includes examples, and features a detailed tutorial.
You can find it here: https://github.com/CuarzoSoftware/Louvre
I hope it proves useful for you. If you decide to use it and encounter any doubts or wish to contribute to its development, please don’t hesitate to reach out.
Greetings!
Lets see if I got this right, you (the OP), the creator of Louvre, managed to create an example compositor that looks like a better desktop experience than the entire KDE and GNOME teams could ever develop with their infinite wisdom and funding? Fucking amazing. :)
I know this is an example, but seriously following the “copy apple down to the last pixel” approach you should consider creating a DE for Linux that doesn’t have themes or any user tweaks, just a simple and pixel-perfect copy of macOS. The problem with GNOME and KDE is that they both fail in simple design principals such as proportions, item spacing and whatnot while Apple, and you by extension, excels in that aspect.
Furthermore my personal opinion is that GNOME tries to reinvent everything and ends up fucking things up and creating situations like the lack of desktop icons going into the activities view by default etc. KDE however does some other stuff right but they fail really badly in terms of proportions and item spacing. Their taskbar is also a shame, for a group that says they want to copy Windows’ style they aren’t doing that well.
Desktop experiences when it comes to design peaked with macOS Monterey (after that Apple did changes to the settings that are still not polished) and in terms of usability they peaked with the release of Exposé, Spaces and later their integration on Mission Control (initially bad but now they seem better).
If you do create a 1:1 copy of macOS desktop experience (and keep it updates) as a new DE you’ll most likely become very popular in no time. It doesn’t need themes, customization and all the personalization that would make it really hard to create, just a simply pixel perfect copy of macOS.
Thanks! While I may have nailed server-side decorations in that example, as you know, there is too much other stuff to take into account to make a DE actually functional. So, I respect a lot what KDE and GNOME do and the innovations they make. I actually want to create a macOS clone, hahaha. That is one of the reasons I started this project. I will soon continue working on a library for exposing global menus in Wayland/X11. Qt allows defining a custom platform plugin, enabling us to plug external systems for managing global menus. Sadly, I think GTK4 no longer supports that, so I believe an approach would be to display a standard menu with basic functions for apps that don’t support it.
Well it seems I’m not the only one then :P
