    The same principles can be applied to jumping from one desktop environment to another, for example, from #Plasma to #Gnome…

    https://tube.kockatoo.org/w/gT1rKp7QWu7S4GYsKtw87x

    … And can provide a way to save the state of an application to disk, stopping the app in its tracks and removing it from memory, so that later you can restore it just where you left off.

      Th combination Wayland/KWin is killing it. We recently had Arjen Hiemstra showing how you can access a remote desktop:

      Something that was seemingly destined to die with X11.

    Compositor handoff to switch between desktops looks legendary! I super hope something like that becomes stable and officially supported somewhere, it would be so fun to use

      If its importance is “Wishlist” (which it is), it is not technically a bug. More like a request.

      If it is really important for you, you should definitely look at this.

        @nora
        If you don’t fix it, then close it.
        But you don’t dare do that either, do you?
        And one could also argue differently:
        the KDE developers don’t give a shit what the users want, because they only want to do their own stuff.
        Ignoring a bug with almost 500 comments and insulting the users (you’re not the first to get mad at me for this) shows me in any case: you do your thing and don’t care about the userbase.
        This way of developing is the reason why KDE never made it to the Company desktops.

          @aschnefuenfzehn @nora Oh… They care a lot about the users
          After all these volunteers were once just users. But that doesn’t that they will impliment every feature every user wants. Yeah, even o
          If the feature request has 500 comments.

          And companies most definitely does use KDE. NASA, LERCS, LIGO, CERN, ALBA Synchtron - and lot of scienty places, in building the first Avatar film and BlueSystem also uses KDE Apps *and* Plasma. I feel like I missed something - oh yeah - Valve.

            @whjjackwhite @nora

            a) This is not a “feature request”, this is a bug
            b) Nate Graham himself has promised that the bug will be fixed (in case you haven’t read the 500 bug reports)
            c) KDE is not only developed by volunteers.
            See: https://curius.de/2021/05/open-source-entwicklung-freiwillige-oder-firmen/
            KDE has unfortunately not disclosed the affiliation of its developers,
            but due to known sponsorships, e.g. by blue systems, one can assume that not all are volunteers here either.

              @whjjackwhite @nora
              The lack of transparency leads one to suspect that other companies also pay permanent developers. Among others Trolltech and SuSE.
              d) The “companies” you mention are for the most part not companies but scientific institutions. You can quickly compile something there if it doesn’t work. This is not the case with companies that have to earn money.
              e) The KDE I find at Cern has the version number 3.

                Look, it comes down to the fact that as far as I know, the vast majority of KDE developers are volunteers with their own lives. There was a given explanation for why it hasn’t been fixed, it was complicated code that was hard to maintain. Its not as simple as someone writing code to reimplement the feature, the feature also needs to be maintained which is a lot of work for a project with so few resources compared to proprietary projects that can afford to pay hundreds of full time developers.

                People requesting that feature to come back are just kind of rude about it, skipping out on basic manners. Personally if I were a KDE developer I wouldn’t want to work on a feature after all that.

        @kde

        This would be amazing for games that take forever to load. When you want to exit the game just save it’s state to the disk, and the next time you want to play it just resume and boom! Instead of waiting for 3 minutes, you can play it almost immediately.

    @kde@floss.social @kde@lemmy.kde.social From the article it seems more of a #Qt win for now (though it does mention patches for many others), but in any case that’s neat.

    Now it all just needs sane ways to interface from #CommonLisp.

    @kde@floss.social @kde@lemmy.kde.social Very cool. Here’s hoping to see this in @gnome one day too.

    PS. I’m sure you’re aware of it but, just in case, the window positions/dimensions appear to be lost on the restart. (An issue I have on GNOME too whenever it returns from suspend.)

    > For X11 this was unfixable; clients relied on memory stored by the Xserver, they made synchronous calls that were expected to return values, and multiple clients talked to multple clients.

    time for X11 bouncer, X11 is network transparent ✨
