Vulnerability discussion

The ability to lock graphical desktop sessions manually allows users to easily secure their accounts should they need to depart from their workstations temporarily.

Check content

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

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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
