GNOME is a desktop environment that is not dependent on any one window
manager in order to control how applications and other features interact
with each other. GNOME can work with a variety of window managers. The
window manager is what controls the window borders, window decorations, and
the functionality of those windows. Currently there are about three or four
window managers that are considered GNOME compliant. Being GNOME compliant
means much more than simply being able to run with GNOME; it also means
being aware of GNOME and what GNOME offers. This includes session
management, desktop settings, and interactivity with applications such as
the GNOME Pager.
The Default Window Manager for this release of Red Hat Linux is a window
manager called Enlightenment. Within Enlightenment there is a tool which
will help you to configure the window manager to your specifications.
