From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello everyone,

I wanted to share with you (once more) the release of Louvre v2.0.0 (C++ library for building Wayland compositors) #linux .

Demo Video.

Highlights of the new features:

  • Screencasting: Now compatible with PipeWire via xdg-desktop-portal-wlr.
  • Session Lock Protocol: Allows for the display of login windows.
  • Layer Shell Protocol: For wallpapers, panels, notifications, etc.
  • New Input Events API: Enhanced with support for touch events, pointer gestures, and pointer constraints.

Release Details.

If there's any protocol or functionality you would like to see added, please feel free to suggest it or contribute to its development!

I agree, all the apps I use run natively on Wayland, but I think there will always be some legacy X11 apps that won't get ported. So, I think I'll implement it, but it is definitely not a priority.

While I understand the need for legacy, I also think at some point legacy should be left alone. If it is really needed for some old app to run, VM should do fine. I don't think missing xorg is ever going to be an issue in 2025+ (well, Electron apps maybe). Yet added and not used features (or seldom used features) is offset with future maintenance burden and/or security issues for no good reason.

This also applies to OpenGL comment. Every code path introduces a maintenance burden. While support of more devices is good, supported devices are super old in this case and the question is - is it worth it? Vulkan drivers should either way be in a better state.

Looks very interesting! I wonder how it works, so I definitely will check it out.

Is super cool, there is a presentation in one of the conferences about it. Architecture is explained somewhere in the docs. Anyway, if you do implement it - this would be a good alternative to https://guacamole.apache.org

Who knows, maybe it would be a money opportunity.

Why?

It's not Microsoft, but actually an open source community running open source forge. Also, it's way faster to use in browser.

Regarding Xwayland, I think so, but with respect to OpenGL + Vulkan, I don't see it as that complicated. It's a matter of configuring contexts and updating Louvre's higher level APIs for buffer allocation and rendering.

Oh, so it basically displays a remote window manager in the browser? For a moment, I thought it was running the compositor directly inside the browser with extensions or something like that, hahaha.

I see. Well, to be honest, I am quite comfortable with GitHub and its features like actions, discussions, etc., and I don't really care if Microsoft owns it as long as it's free. But thanks for the suggestion.

I saw it basically months ago, so don't remember 100%. To not say the wrong thing, you can read about the architecture here: https://greenfield.app/pages/design/

Also, here is a video. The dev demonstrated it's fast enough for gaming https://fosdem.org/2024/schedule/event/fosdem-2024-3219-greenfield-wayland-in-the-browser-an-update/
