Chapter 4. Locking Down the
Desktop: Disabling GNOME Desktop Features
The GNOME desktop can be configured to restrict user access to a
number of actions, such as printing, access to the command line,
and even the ability to log out of the system. The most restricted
configuration can be used to form the basis for a public terminal
configuration or that of a kiosk-like setup, in which the user can
only perform simple functions like web browsing. This chapter
provides the essential information needed by administrators to
perform the various tasks related to locking down the desktop.
Most of the restricted access can be configured using GConf
key/value pairs, hence these will be discussed first.
To disable the ability to log out and to lock the screen, set
the appropriate keys under /apps/panel/global/ using the GConf editor.
The keys to set are
/apps/panel/global/disable_log_out
/apps/panel/global/disable_lock_screen
