  • Taking courses which involve subjects that you will likely never encounter in the workforce is a thing in every discipline. Most engineers don’t need to manually solve differential equations in their day jobs, they just need to know that they exist and will often require numerical solutions.

    Getting your hands dirty with the content provides a better understanding when dealing with higher level concepts.












  • Well, those requires D-Bus. The wlroots project decided early on to support non-dbus software stacks, so wlroots compositors expose Wayland protocol extensions which could either be used directly or wrapped by the xdg-desktop-portal-wlr daemon.*


    *(Well… many wlroots devs argued that the ecosystem should have chosen WP extensions instead of dbus, but I think most relented when Pipewire entered the equation.)



  • 14 years later the need is slowly growing so the support is slowly growing

    Yes! I agree wholeheartedly. Adoption has been slow because Wayland did not meet the needs of most people more than Xorg did. Cinnamon isn’t moving any time soon because the value-add isn’t enough for the average desktop user.

    But…

    build something that people need

    People have needed HDR and VRR for years. HDR is essential for professionals in video and image editing. They needed Wayland years ago, and it was being built with them in mind, not just the average desktop user in 2012.

    Not every feature is used by every user of that software. I used X-forwarding over SSH once, ever. It did not add any value to me. SSH forwarding adds no value to the average user either. But it is essential to someone.


  • They are becoming more essential by the day. HDR and VRR is supported by just about every graphics card for the last 5 years, and displays which support both can be found for $200 or less. Valve had a reason to add HDR support to Gamescope/Steam Deck; it is a highly requested feature.


    I will agree with you on one point: Xorg is not bad code. Xorg is an awesome project, and has developed and changed to the needs of users exceedingly well for decades. But X11 itself is tech debt. The first ten years of Wayland were spent paying that debt off (while simultaneously continuing Xorg development).

    If the features aren’t what you need, then Wayland wasn’t built to support you today. But you might find yourself in 6 years looking at a gorgeous HDR display which works out-of-the-box on your favorite Linux distro thanks to Wayland.


  • features

    • mixed refresh rates
    • (not GNOME) mixed VRR/nonVRR
    • (not GNOME) Better mixed DPI?
    • (not yet, experimental in gamescope) HDR support
    • (not yet, experimental in KDE) persistence through compositor restart

    It was the inability to add features like mixed refresh which caused Xorg devs to push for a new protocol. Otherwise it would be yet another series of janky patches to break assumptions made in a 40 year old protocol.

    Other devs have been working on it. Valve’s contributions to wlroots, KDE, and gamescope can’t be understated.
