    Phoronix: KDE Enjoys Improvement For Much Better NVIDIA Wayland GBM Experience

    A QtWayland module change has landed that should greatly improve the NVIDIA Wayland experience when running the KDE desktop on modern NVIDIA drivers offering GBM API support...

    How soon will this be released? Would be nice to use Wayland on my KDE install.

      That would be up to the distro. KDE maintains a patch set for QT5, and its up to distros to then take that and build/package it.

        Very, very nice. But the question remains: why did it take so long to realize you don't poll on a thread that has other stuff to do?

        Edit: Yes, my 1060 is again happy with KDE/Arch. Still missing the night light, but that was never working on Wayland anyway.

          Cool, I guess, but I could never understand why people stick with a really open source hostile company...

            It's up on Arch!

            The difference is huge, went from unusable to much faster than X11. I might actually start using it now

              Horrible reality qtwayland is 2014.

              X11 is still shoving almost everything though a single thread until 2016.

              So yes qtwayland looked at x.org X11 server and copied the mistake. Yes its taken them 6 years to finally start fixing it copied mistake.

              You were not thinking this was a copied mistake.

                I'm not sure how a history lesson is relevant here. I'm just curious how this misplaced polling didn't cause performance issues before. The obvious explanation would be polling takes much longer on Nvidia hardware than on AMD or Intel, but that's also strange and I have no data to back that up.

                  Yes, when it is made workable, Wayland provides notable progresses, such as to forget any previous graphical platform.

                    Have you get the package from the repository, or installed it on your own?
