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
