Fix Recommendation

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 "<Control><Alt>l"

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

Check Contents

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.
