As in KDE to set the Wallpaper the user from the console?
Did the task - set on more than 10 thousand computers all users of a particular Wallpaper on the lock screen and desktop. How to do a specific user through the GUI I know, but as I can not find how to do it from the console. Including to new users who have never been on a computer. Walk to run or connect to the users is very expensive, much easier and more convenient to make the scenario in ansible. But somehow the gugleniya does not answer this question.
