    What about when not using gamescope? How would you use HDR then?

    To be fair, Wayland had a lot of other pain points to deal with first, so it wasn't a huge focus. Plus, too many systems still ship with X11 by default for other parts of the stack to invest... It was probably smart to focus on foundational issues before hitting new features.

    Now that Wayland is (mostly) caught up, once it's widely accepted as standard I imagine future display innovations will land much closer to general hardware availability.

    That said, one thing I do worry about is that new tech will probably have a bit of a fractured initial experience - if the Wayland Protocol doesn't very quickly standardize upcoming technologies. In the year 2030 if something like 3D displays become the new big thing, I'd hate to see Gnome and KDE push duelling implementations because the Wayland maintainers dragged their feet.

    Well, between X which is too old to be retrofitted with all the bits and pieces needed by HDR and Wayland who thinks said bits and pieces are not a priority in a next-gen display server, what did you expect?
    I mean, it took years for Wayland to figure out fractional scaling, HDR may be a multi-decade problem for them.

    It's always hard when you don't know. It's basically an inductive process (which takes time). Or a deductive that has an inductive process to find out (which takes time). Also add, it has to follow a certain mindset as well (project's mindset of principles).

    Without principles it will become chaotic and more often than not, bad.

    Sadly, the Kwin support is just one piece of the puzzle. By the way, CachyOS already carries some HDR patches for AMD hardware. There is also an Xorg/Wayland part for supporting HDR and probably some other components that I haven't mentioned yet.

    It is a bit sad that it is the end of 2023 and the Linux ecosystem still lacks behind here by a few years. But there is light at the end of the tunnel.

    I wonder if we will see HDR support with Kwin on Xorg though as KDE devs seem focused on Wayland these days.
    Bloody hell, I'm good to go then. That's a pleasant surprise

    I didn't realize CachyOS picked the HDR patches back up and all the rest, aside from KWin, is already installed and up-to-date on my system. That's what I get for not checking what patches the custom kernel I'm running is using . Luckily, I already had it running and have been keeping it up-to-date in anticipation of HDR coming back. Now I'm upset that I have actual stuff to do today

    I need to get my KDE build environment back up and running.

    That's pretty cool!
    I wish KDE organization had more sponsors / donors to make more cool things like this!
    They haven't reached even 50% of their 500 members goal:
    Keep us Going! You helped us reach our goal of getting KDE supporters to 1000 and beyond!


    After games, I hope they can solve the HDR problem for movies and videos playback too!
    Too bad that even for games it requires an up-to-date gamescope, which will be hard to find / install in the majority of distros.

    HDR isn't possible in xorg I'm pretty sure.

    Does this mean that the Linux-HDR patches aren't needed? I just didn't see that mentioned anywhere in the MR or use instructions for any of this.
