About GNOME:

GNOME 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 programs which manage application launching, file handling, and window and task management.

GNOME is part of the GNU Project and can be used with various Unix-like operating systems, most notably Linux, and as part of Java Desktop System in Solaris.

The name originally stood for GNU Network Object Model Environment, though this acronym is deprecated. The GNOME project puts heavy emphasis on simplicity, usability, and making things “just work”.

Requirements:

Limitations:

• In some flavors of Gnome 2.32 the right-click menu on some panel applets have a white text and uses the pixmap hover effect. There is no known fix for this.
• Earlier versions of Libreoffice has missing scrollbars. An upgrade to Libreoffice 3.4 or later fixes it.
• Dialog windows in Gnome 3 fallback mode have weird borders. My current recommendation is that you detach them with gconf-editor. Open gconf-editor and untick this key: /desktop/gnome/shell/windows/attach_modal_dialogs.
• Legacy metacity theme is not borderless. (It does not look good.) Use gnome-shell to get anti-aliased rounded corners.
• The IDE software Eclipse/Aptana may have some strange color bugs. If you know of any fixes, please let me know.
