CHAPTER 6
Launching Your
Desktop
When you normally log in to openSUSE, you use a
graphical login screen. That screen, a display manager, is
your first taste of the X Window System, more often called
X11, or just plain X. X has a much longer history than
Microsoft Windows, but it is similar in many ways. It has
also gone through more than a few changes along the way.
The most recent change is a revival of development from
the X.org Foundation, the official owners of X. Earlier
versions of SUSE Linux included an open-source version of
X for the Intel platform called XFree86; openSUSE uses
X.org version 7.2.
X uses a client/server model in its architecture, but it??™s a
little different from what you may think. Normally, you are
working with a client on your PC that makes requests on
your server, which is remote. With X, the server is installed
on your machine. It accepts requests from any number of
clients, which can also be on your machine, or connected
from a remote location (like a Telnet session). X Servers
supply the graphics drawing protocols and much of the
network communication to support clients??™ libraries.
