    Phoronix: Qt Is Now Drawing On Wayland

    Last week in Toulouse I learned just how much interest Intel has in Wayland and the active role they are playing in its development. Wayland and related work to bring it up is not limited to just Kristian Høgsberg, who switched from being a Red Hat employee to Intel during Wayland's development, but Jesse Barnes and other Intel OSTC X developers are also contributing to different areas. Jesse Barnes has been working on the Qt support within Wayland and that's hit a new milestone...

        This is very good news.
        I was doubting Intel's interest in Wayland, precisely because they weren't mentioning Qt support, while they are quickly moving to Qt internally.

          Wayland is X.org, stripped from everything that's old, the libs and the network protocol and pushes the latest technology, such as KMS, Gallium3D, OpenGL ES, EGL, etc.

          It's not, by any means, X11 or 'X12', but just a tiny display server.

          It can, however, use X.org's server for Xlib software and client-server computing.

          QT and GTK+ are using Xlib, so they must be ported over to Wayland in order to run without the X.org server, which is what is happening now.

          Wayland, due to being tiny and clean, is great for embedded devices, which MeeGo targets.

          So basically Wayland is the BusyBox equivalent of X.org.

            so.. its great news, finally something not bloated?

            all what i need is fast response, no redrawing, no flicker, no "cool stuff" like compiz, just be able to work with very low resource consumption and allows to run drivers and fullscreen programs flawless.

            someone knows when it will be ready to use? even beta ?

              I doubt anytime soon. For now it requires Cairo with GL backend which as far as I've been able to decipher is still not nearly production-ready.
              In other words, even if you got a release, you couldn't use it.

                i am curious to see which will be the first desktop environment that will run on Wayland

                  You do realize this "cool stuff" uses your resources more efficiently? It's using the GPU for rendering instead of wasting precious CPU power.
                  Wayland will rely heavily on the GPU, which is a good thing, just like Compiz is.

                    Considering that KDE is actively pursuing getting into mobile space, I'd guess its Plasma workspace will be the first to run without the X11 compatibility layer.

                      And Gnome is probably too busy with getting Gnome 3 shipped and GTK+ is probably too busy with their next itteration.

                        Why's Wayland running in an X window?

                        Yo dawg, so you like X, so we put X in your wayland in your X in your wayland in your X....


                        Or did I totally misget that, and that screenshot is a wayland window?

                          ..I suspect he's running wayland in an X window so he doesn't have to keep restarting his environment to test..

                          Point is, wayland works with the screen as a GEM object, so it can just as well render to the object of a surface that's in an X window as it can the front buffer object.

                              Those Intel guys know how to build high-performance graphics hardware and stable drivers, so Wayland MUST be good if they back it!
