I find instructions at https://docs.xfce.org/xfce/xfconf/start hard to follow. There is a chapter about Kiosk mode. It tells
Locking a channel or property is as simple as creating a configuration file and setting either (and only either) the “locked” or “unlocked” attribute on or elements that should be restricted. This configuration file should be placed in a system location that is read by the daemon (see “File locations” above).
What is the syntax of such a configuration file? Where are the "File locations"? Should the file be created, when Xfconf is not running? Can you terminate Xfconf during a Xfce session, or should you log out before creating the file?
