Without a window manager
, X is not very useful.
You can still launch applications without one, but you cannot resize or move the X windows, nor can you customize X windows appearance.
Enlightenment, the default Red Hat Linux window manager, is a versatile, highly customizable window manager. With Enlightenment you can:
Move and resize windows
Customize taskbars, title-bars, and borders
Work with virtual screens
