 If your image is older than 20191214 and you want to install the customizable Nexus desktop background, you must do run these commands in the Terminal before you can run the new 'Edit Desktop Background Text’ script (__NOTE: This will REPLACE your current desktop background__):

 After you start the script (__Raspberry > Preferences > Edit Desktop Background Text__), enter the text you want to display and optionally check the box to show your Pi's host name, then click __OK__.  The script won't close until you Cancel, so click __Cancel__ when you're satisfied with your new desktop.
