The XFree86-AGX package contains the X server for AGX-based cards,
such as the Boca Vortex, Orchid Celsius, Spider Black Widow and
Hercules Graphite.
If you are installing the X Window System and the video card in
your system is an AGX, you'll need to install XFree86-AGX. You
will also need to install the XFree86 package, one or more of the
XFree86 fonts packages, the X11R6-contrib package, the
Xconfigurator package and the XFree86-libs package.
Finally, if you are going to develop applications that run as
X clients, you will also need to install the XFree86-devel
package.
