Fix Recommendation

Run the following command to set the screensaver mode in the GNOME desktop to a blank screen:

# gconftool-2 \
--direct \
--config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory \
--type string \
--set /apps/gnome-screensaver/mode blank-only

Check Contents

If the GConf2 package is not installed, this is not applicable.

To ensure the screensaver is configured to be blank, run the following command:

$ gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --get /apps/gnome-screensaver/mode

If properly configured, the output should be "blank-only".
If it is not, this is a finding.
