One week after a desktop developer meet-up
, the lead developer of the KWin window manager, Martin Gräßlin, has written about the history of using KDE/KWin on the Wayland Display Server.
Martin's blog post began by talking indirectly about Canonical abandoning Wayland in favor of Mir for future releases of Ubuntu Linux, Wayland support for KWin has been a primary goal of Martin's for the past two years, it took a while for Wayland 1.0 to have a stable and reliable API/ABI, and then earlier this year plans were talked about the KDE/Qt5/Wayland combination.
Martin made it clear in his posting that their Wayland plans were laid well before Canonical's Mir+Ubuntu announcement. I've been talking about Wayland and KDE/KWin since at least 2011
and more details later that year
Wayland remains to be part of KDE's long-term strategy and so far it's proving to be good. Martin's Sunday afternoon blog post can be read here
