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

Verify the keybindings for the Gnome screensaver:

# gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --get /apps/gnome_settings_daemon/keybindings/screensaver

If no output is visible, this is a finding.
Fix Text (F-43420r1_fix)
Run the following command to set the Gnome desktop keybinding for locking the screen:

# gconftool-2
--direct \
--config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory \
--type string \
--set /apps/gnome_settings_daemon/keybindings/screensaver "l"

Another keyboard sequence may be substituted for "l", which is the default for the Gnome desktop.
