Other Desktop Environments
 
Both Gnome and KDE are full flagged Desktop Environment for *Nix systems. Apart from these two there are a lot of other Desktop Environments & Windows Manager that are used with different type of *Nix System, most notable among is Xfce. Xfce is a very lightweight DE and popular too.
 
Here we will discuss some of them:
 
Xfce(Complete DE)
 

 
Xfce is a lightweight desktop environment for UNIX platforms. It is similar to the commercial CDE, and is now based on the GTK+ toolkit.
 
A strong point of Xfce is its ease of configuration - it is driven entirely by the mouse. The latest version features drag and drop, session management, translations for numerous languages, including support for multi-byte character sets, and numerous other features.
 

 
The desktop environment includes a window manager, called XFwm, the main panel, a file manager, a backdrop manager, a sound manager, a calendar, a pager module, and a GNOME compliance module.
 
CDE (Common Desktop Environment)
 
The Common Desktop Environment (CDE) is a commercial graphical user interface for UNIX in its various flavors (AIX, Digital UNIX, HP/UX, Solaris, UnixWare, etc.). The desktop has been jointly developed by Hewlett-Packard, IBM, Novell and Sun Microsystems. It has been adopted as a standard operating environment by these companies and many others in the UNIX workstation market.
 
The CDE incorporates the dtwm window manager. This is a Motif-compliant, virtual window manager and is similar to the HP/UX program vue.
