Re: Where is the Wayland process?

Hello,

The Wayland protocol merges the server and the compositor:
https://en.wikipedia.org/wiki/Wayland_(protocol)#Differences_between_Wayland_and_X

so your wayland server process is your wayland compositor (kwin_wayland) 
process. The wayland compositor is roughly equivalent to xserver+wm for X11.

Xwayland is the compatibility layer offered by the protocol to the 
legacy X11 applications that are not compatible with it (if you have 
modern applications developed in GTK or Qt, for example, they are 
natively wayland compatible and xwayland is not required).
