[CentOS] gconftool-2 for 7

on 6 the command:
gconftool-2 -t bool --list-type bool --set
/apps/gnome_settings_daemon/screensaver/start_screensaver false

would stop the screen saver.

What is it on 7. The above seems to do nothing.


Also
The gnome-panel process was running in 6 - it does not seem to be
run in 7. How do I hide/remove the top and bottom panel?

The "hide" in gconftool-2 for top and bottom done seem to do anything
either.

What might I be missing?
Thanks,

Jerry
