Raspberry Pi Desktop


When the Raspberry Pi powers up your screen will display a spectrum of colours.  These colours are only displayed for a very short time and then the screen will be filled with scrolling messages.  The Raspberry Shake image uses the LXDE window manager for the desktop.  Depending on the distribution you are using you may find that a different window manager is installed.  This tutorial will only cover the LXDE window manager on the Raspberry Pi.

The Raspberry Pi Desktop

The desktop is used to make the user experience more intuitive by providing visual buttons, menus, icons and windows.  The desktop removes the complexity of manually entering commands in a terminal which is explained in further tutorials.  LXDE has been selected for the Raspberry Pi because it is light weight, uses less processing power than most window managers and does not require 3D acceleration to complete graphic tasks.  LXDE can be customised for your own desktop preferences.  It also uses very low memory making it ideal for the Raspberry Pi and other small low powered devices.

Some features of the desktop are:

File manager

The file manager is used to manage files by providing an easy interface to display, copy,  delete and edit a file.  It also provides a way of navigating throughout the Raspberry Pi file system.
