Why do that?

As far as I can tell, Xwayland is automatically started as part of the Wayland session. You don’t need to start it.

What are you trying to do?
Normally XWayland is not necessary, Wayland is implemented as a socket service and not with or as an X Server.
A Wayland X server may be required only for special situations where an application expects to connect to an X server.

Thank for help and sorry to waste your time :slight_smile: .
Running Xwayland under Wayland session is suggested as the best way to get Xpra server with graphic acceleration. Xpra server is extra software, which allows to allow access to desktop (Video, Sound, clipboard, etc.), printers remotely.
I will test is there another way.
