Preseed gnome-screensaver lock value

[Juanjo Pablos]

Hi,
I would like to disable the gnome-screensaver lock using a pressed file:

on command line, I can type:

gconftool-2 --direct \

   --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory \
   --type bool \
   --set /apps/gnome-screensaver/lock_enabled false


and I found a reference on this list:
https://lists.ubuntu.com/archives/ubuntu-installer/2010-November/000709.html

but I am not sure if the command is:

d-i /apps/gnome-screensaver/lock_enabled false


can anyone confirm if this is the right way to achive?

Thanks!
