Common Desktop Environment (CDE) is a graphical interface that provides a consistent look and feel across UNIX environments. To help you organize and manage your work, the desktop provides windows, workspaces, controls, menus, and the Front Panel. These objects provide a new standard for user and application interfaces based on the X Window System and Motif.
CDE has more features and functionality than Open Windows or X Windows and has a much friendlier user interface. To use CDE, type in your username and password as prompted in the Desktop Login box.
Once you login, you will see a
Terminal window and a
Console window. You can execute UNIX commands in the
Terminal window. The
Console window will
display system messages to you. You will also see a
Front Panel with several icons across the bottom of the screen.
Desktop Window Manager (dtwm)

other components in the environment, such as the
Session Manager (dtsession) and the
Style Manager (dtstyle). Many other components are started through interactions with the
The dtwm window manager includes functions that facilitate control (by the user and the programmer) of
elements of window state such as placement, size, icon/normal display, and input-focus ownership.
In addition, dtwm provides workspace management.
Workspaces provide a way of grouping together logically related windows. Each workspace is shown independent of the other workspaces so that only those windows related to the immediate task are visible. Workspaces give you a tool to organize windows by task and make efficient use of screen real estate.

Front Panel may contain additional or different controls. These terms are used to describe controls:
- Click – What happens when you click the control
- Drop – What happens when you drag and drop a file or folder icon onto the control
- Indicator – What the image of the control represents
