setting gnome options

While searching for how to disable the face browser (list of available users on the login screen) in gnome 2.22, I found the command line method for updating system wide gnome settings.

First to disable the face browser and shutdown buttons on the gnome login screen

sudo gconftool-2 --direct \
 --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults \
 --type bool --set /apps/gdm/simple-greeter/disable_user_list true
sudo gconftool-2 --direct \
 --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults \
 --type bool --set /apps/gdm/simple-greeter/disable_restart_buttons true

And while initially installing the server I wanted to change the power settings for the laptop lid, ideally from the command line, I see that I can do these with these commands,

sudo gconftool-2 --direct \
 --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults \
 --type string --set /apps/gnome-power-manager/buttons/lid_ac blank
sudo gconftool-2 --direct \
 --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults \
 --type string --set /apps/gnome-power-manager/buttons/lid_battery blank

to make the closing of the lid just blank the screen instead of going to sleep. I actually set these through the power configuration applet when I did them the first time.
