<para>The GNOME desktop is the default desktop of Ubuntu 7.10. GNOME (GNU Network Object Model Environment) is an international effort to build a complete desktop environment—the graphical user interface, which sits on top of a computer operating system—entirely from free software. This goal includes creating software development frameworks, selecting application software for the desktop and working on the programmes which manage application launching, file handling and window and task management. Community members worldwide contribute to the translation and accessibility of the desktop in multiple languages.
