KDE’s X11 Support to Continue Until Plasma 7
Quoting: KDE's X11 Support to Continue Until Plasma 7 —
This change marks a shift in how desktop environments can be deployed on Linux, as KWin X11 and KWin Wayland are now fully co-installable without any direct conflicts.
Consequently, when KDE Plasma 6.4 is released (scheduled for June 12), individual Linux distributions can opt to include only KWin Wayland or ship both KWin X11 and KWin Wayland, depending on their default display protocol and user preferences.
Moreover, it is worth noting that KWin Wayland is now “de-facto” KWin moving forward, meaning users and distros will likely continue to see it simply packaged as “kwin.” While the naming decision ultimately lies with each distro, the KDE team recommends that any “kwin” package now be recognized as “kwin_wayland,” reflecting the project’s focus on Wayland.
