Can you just uninstall the screensaver? If you have ubuntu-desktop
installed, you would need to uninstall that first, since
gnome-screensaver depends on it. Note: ubuntu-desktop is a
metapackage, meaning that it doesn't actually contain anything by
itself other than dependencies. Removing ubuntu-desktop will not
remove any other packages unless you manually remove them (e.g., the
screen saver).

This I am not sure how to do, if it's even possible. There is a
/etc/gksu.conf file, but a quick glance doesn't indicate if that
option is possible. Perhaps the manpage would have something about
