Check Text ( C-53295r2_chk )
If the GConf2 package is not installed, this is not applicable. To check the current idle time-out value, run the following command: $ gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --get /apps/gnome-screensaver/idle_delay If properly configured, the output should be "15". If it is not, this is a finding.
