How can I remove the four items on screen? Applications, Places home trash from the command line? I'd prefer to remove the top panel and bottom panel all together if possible, but they can stay - I just don't want anything showing on the screen. searched all around for kiosk mode gnome3 etc.. not finding anything good for CentOS7. Was able to do this in CentOS 6 can't believe they took out functionality. Any way to "not" have those menu items and not have icons on the main screen? Thanks jerry
