KDE Plasma 5.5 on Wayland will feature Screenlocker integration in KWin

Bhushan Shah recently posted on his blog page, an on going project work he has been working on to integrate the Lockscreen with KWin Wayland session. According to him, this is the most important bit of the Plasma on Wayland session. Currently in X11 lockscreen is managed by ksmserver (KDE’s session manager). Its also noted that in Wayland, lockscreen functionality should be moved in kwin_wayland, so that compositor is aware that screen is locked, what windows are owned by greeter, and what should get input events.
