2.1. Introducing GNOME Desktop Components
When you start a GNOME Desktop session for the first time, you should
see a default startup screen, with panels, windows, and various icons.
The major components of the GNOME Desktop are as follows:
Panels
Panels are areas in the GNOME Desktop from which you can access all
of your system applications and menus. Panels are very configurable.
A particularly important panel is the top edge panel. The top edge panel includes
the Menu Bar. The Menu Bar
contains two special menus, as follows:
Applications menu: Contains all applications
and configuration tools. This menu also includes the file manager and the
help browser. To start the file manager, choose Home Folder
from the Applications menu.
Actions menu: Contains various commands
that perform various functions, for example Search for Files
and Log Out.
Click on the Window Selector icon
at the extreme right of the top edge panel to display a list of all open windows.
Menus
You can access all GNOME Desktop functions through menus. You can use
the Applications menu to access almost all of the standard
applications, commands, and configuration options. You can access the Applications menu from the Main Menu and from
the Menu Bar applet. You can add the Main Menu and the Menu Bar applet to
your panels.
The Menu Bar applet contains an Actions menu. The Actions menu contains commands
that perform various functions, for example Search for Files
and Log Out. The items in the Actions menu are at the top level of the Main Menu.
Windows
You can display many windows at the same time. You can run different
applications in each window. The window manager provides frames and buttons
for windows. The window manager enables you to perform standard actions such
as move, close, and resize windows.
Workspaces
You can subdivide the GNOME Desktop into separate workspaces. A workspace is a discrete area in which you can work. You can
specify the number of workspaces in the GNOME Desktop. You can switch to a
different workspace, but you can only display one workspace at a time.
Nautilus file manager
The Nautilus file manager provides an integrated
access point to your files and applications. You can display the contents
of your files within a file manager window, or open the files in the appropriate
application from the file manager.
You can
access your files and folders in the following ways:
Desktop
The desktop is behind all of the other components on the desktop. The
desktop is an active component of the user interface. You can place objects
on the desktop to quickly access your files and directories, or to start
applications that you use often. You can also right-click on the desktop to
open a menu.
Start Here location
The Start Here location provides an access point
to some of the key features of the GNOME Desktop. You can access your GNOME
applications and configuration tools from the Start Here
location. You can also access programs that enable you to configure your system
as a server, and to modify other system configuration details.
Preferences
The GNOME Desktop contains dedicated preference tools.
Each tool controls a particular part of the behavior of the GNOME Desktop. To
start a preference tool, choose Applications->Desktop Preferences. Choose the item that you want to configure
from the submenus.
The most powerful features of the GNOME Desktop are the high degree
of configurability and the multiple ways that you can perform tasks.
The components of the GNOME Desktop are interoperable. Usually, you
can perform the same action in several different ways. For example, you can
start applications from panels, from menus, or from the desktop.
Your system administrator can make configuration changes to suit your
needs, so that the GNOME Desktop that you use might not be exactly the same
as described in this chapter. Nevertheless, this chapter provides a useful
quick guide to how to work with the GNOME Desktop.
