1. Introduction

Xfce is a lightweight desktop environment for unix-like operating systems. It aims to be fast and light, while maintaining a pleasant appearance and a high usability.
Xfce embodies the traditional UNIX philosophy of modularity and re-usability. Consists of several components that provide the full functionality that you would expect from a modern desktop environment. They are packaged separately, and you can choose packages, to create your own desktop environment.

Another Xfce priority is adherence with standards, particularly those defined by freedesktop.org.

2. Using Xfce

2.1 To begin

2.1.1 Login Manager

Xfce4-session install a file that should add an option for the operator access to start the Xfce session. Xfce Desktop Environment does not have its own DM, but there are various options such as gdm, slim, and lxdm lightdm.

2.1.2 Command Line

Use startxfce4 to start Xfce session or choose "Xfce Session" in the login manager, which includes the session manager, the panel, the window manager and desktop manager. Read auto login from console for more infos.

By default, the "Xfce session manager" handles the Applications Launcher. It allows you to save your session when you turn off Xfce, so that the next time you log in, will be automatically launched the same applications.

2.2 The default Desktop

The Xfce Desktop Environment is not a single entity that provides all the functionality, but rather tries to join the old UNIX tradition of small tools that do one thing and do it well.
When you start Xfce session for the first time, many applications are started by Xfce session manager:

Panel
In a default session there is a panel with full width in the upper part of the screen and a smaller one in the lower part. The Panel tool manages all panels on the screen.
The top panel shows a graphic pager with thumbnails of all workspaces, a list of the running applications on the current workspace, and a system tray with the status icons of some apps, such as media players or instant messenger.
The bottom panel shows many application launchers and a clock. You can right-click on any item in the panel, to enter in a menu through which changing its properties, add or remove new items.
Desktop Manager
The desktop manager provides the desktop background, and two menus when you click on the desktop background. It can optionally show icons on the desktop, and files stored in the /Desktop folder.

The middle mouse button (or use the Shift + left keys) open a list of all running applications. You can activate an application by clicking on its item in this menu.
Window Manager
The window manager is responsible for apps windows placement on the screen, and applies the windows edges, and their decorations. It allows you to move windows by dragging the title bar, and applies buttons on the title bar, for example to close, minimize/maximize a window. Take a look at the manual for a full explanation on configuring the window manager.
Settings Manager
The Settings Manager works behind the scenes, and ensures that all Xfce applications update their configurations, if the user changes something in the Settings Manager, readings configurations from the hard disk at the boot time. Take a look at the Settings Manager for a complete explanation about it.
