Guide to GNOME Lockdown and PreconfigurationSayamindu Dasgupta                     <sayamindu@gnome.org>                 Copyright © 2007 Sayamindu DasguptaRevision HistoryRevision 0.220th August, 2007Revision 0.115th June, 2007 Lockdown is the mechanism which is used to bar users using a computing environnment from performing certain actions (like, for instance, printing files, or saving files to disk). The GNOME Desktop already has lockdown support in a few areas (especially the panel and the epiphany web browser). This document aims to cover all the lockdown features found in GNOME, as well as act as a guide on how to preconfigure the desktop settings. The existing GNOME System Administration Guide provides an excellent overview of the GNOME Desktop from an administrator's perspective. However, it does not, in its current form, delve deep into the tools and methods for performing lockdown and preconfiguration. This document aims to cover that gap and act as a complementary document to the System Administration Guide. It is assumed throughout that the reader of this document has already gone through the GNOME System Administration Guide. Introduction This document aims to serve as a guide for setting up the GNOME Desktop (or multiple instances of it) for mass scale deployment. It also explains on how to tweak GNOME for special kind of deployments (unmanned kiosks, public internet access terminals, etc). An administrator in virtual any kind of deployment (other than the one in a normal home desktop system) usually has to perform two categories of actions before the deployment can be rolled out. They are described in brief below. Lockdown Lockdown is the process of disallowing the users from performing certain actions. "Certain actions" can range from changing the desktop wallpaper to saving any kind of to the hard disk. At present, GNOME lets the administrator define any setting in the Desktop as mandatory, meaning that it will not be changeable by the user. Also, quite a few components of the GNOME Desktop define lockdown settings of their own. For example, the GNOME panel can be setup to allow a specific set of applets and action buttons. Pre-configuration Apart from lockdown, the desktop administrator will almost certainly need to preconfigure certain aspects of the Desktop. In a typical deployment this may include changing the look and feel of the desktop and/or the proxy servers. However some of these settings may need to be locked down or made mandatory depending on the type of deploymen

Note that this group builds on the gnome group. The base desktop consists of GNOME Shell, a plugin for the Mutter window manager. It can be installed separately with gnome-shell. Note: mutter acts as a composite manager for the desktop, employing hardware graphics acceleration to provide effects aimed at reducing screen clutter. The GNOME session manager automatically detects if your video driver is capable of running GNOME Shell and if not, falls back to software rendering using llvmpipe.
