The X Window System
Probably the most popular way to interact with any Unix-type system
is via the X-windows interface. The free implementation of the X Consortium's
X11R6 is XFree86.
I. Default XFree86 and Related Packages in Fermi Red Hat Linux v5.0.2
XFree86-3.3.2.3-18
XFree86-75dpi-fonts-3.3.2.3-18
XFree86-libs-3.3.2.3-18
XFree86-<server>-3.3.2.3-18
X11R6-contrib-3.3.1-1
xserver-wrapper-1.1-1
Where <server> is the correct server for the video card in a system.
II. Configuring X windows with Xconfigurator: Why?
A. XFree86 is different from X11R6 because it runs on a plethora of
PC video cards, unlike, say, Sun or SGI which only have one or two options
for video cards. So, when installing XFree86, you need to know what server
(the actual binary that talks to the video card) to use with the hardware
that's installed. Currently, there are 13 choices in the standard distribution.
B. Which server for which video card: use Xconfigurator
1. PCI Probing should detect the correct card.
2. If the correct one is not installed, use rpm to install it:
a. Utilize the simple ftp client built into rpm to install the server:
rpm -ivh ftp://linux.fnal.gov/linux/current/i386/RedHat/RPMS/XFree86-<server>.i386.rpm
3. Restart Xconfigurator and continue.
