    Phoronix: The State Of The Wayland Display Server

    Last year the Wayland Display Server project was started by Kristian Hogsberg, a Red Hat developer and a name known well within the X.Org community for his work on AIGLX, Direct Rendering Infrastructure 2, and various other projects. We were first to talk about the Wayland Display Server in detail, which aims to provide a mini display server that is designed around the latest X/kernel technologies like the Graphics Execution Manager and kernel mode-setting. Wayland also integrates its own compositing manager and is designed to produce a perfect frame (a.k.a. no tearing) each and every time. There has not been much to report on this project recently, but we now have a status update courtesy of Kristian.

    good news


    so practically as soon as we have GTK+ running in wayland we'll be able to have Gnome and XFCE right?? (or at least most of the apps)

      He is also looking at the possibility of running a rootless X Server on Wayland so that Wayland can pull windows from the X Server into the currently running Wayland server session. This feature would be very interesting.
      Does this mean that in the future a Wayland could be helping in providing graphics for some of the windows in a running X.org server?

      There has been a lot buzz on hybrid graphics and it's status in Linux. Is it possible that in the future a Wayland server could be plugged to the hot-switchable graphics card in the laptop, that is turned on/off without reboot depending on the required tasks, whereas the main X.org could be using the other graphics card?

        Other way around - Wayland would be rendering and compositing the desktop, but this would only let you use client drawn apps. So there would be an X server running rootless so you could use legacy apps. The X applications would then be pulled from the X server and would be composted with the normal ones.

        It would be a lot like how Mac OS X handles X applications.

          Excellent news, +1 up for GTK+, GNOME, and its derivatives .

            Hehe, they'll sooner or later bring support for QT, but it's sad they first support this thing... Modern display server and old gtk - it doesn't look so good...

              +1 for Qt4, KDE, and its new technologies!

                  +1 more for QT4.

                  Honestly though, *whatever* encourages maximum effective development on upgrading X.org's creaky display server. If getting GTK up gets a mass of developers extending Wayland so it survives and thrives and becomes the modern display server Linux needs... well, I'll be happy.

                  Of course I'll be even happier when QT4 is added to the mix. (I love me some KDE 4, I do)

                    If Wayland can integrate ALL of X's functionality, and even do it rootless, seamless and unnoticably, it has a great future

                    All of Wayland's advantages, along with those of X.. *drool*

                      It's funny how KDE and Qt fans say nonsense like this and then complain whenever anyone mentions the horribly mismanaged KDE 4.0 and 4.1 releases...

                        Goes both ways.

                            So would it be possible for the Wayland+X.org configuration to work on two different graphic cards, one integrated and another one discrete?

                              That has been worrying for me on Wayland (and I can't seem to find any info on this).

                              The _only_ reason I think that X is awesome, is because it's a client-server model. So, for example I can have my applications running on my server and displaying them on my computer.

                              Mac OSX can't do that. I just hope Wayland will continue to be client-server. Else, I won't bother, as VNC just doesn't cut it.

                              Anyone has more info about this?

                              Cheers,
                              Benedikt
