      This miniHOWTO is about how to install the OpenGL drivers for
      Nvidia graphics cards on Linux.  In addition to just installing the
      Nvidia drivers, this mini-HOWTO also explains how to install XFree86, the
      OpenGL Utility library (part of Mesa), the OpenGL Utility Toolkit (glut),
      the full set of OpenGL manpages, Qt and its OpenGL extension, and Java and
      its Java 3D extension so that a user can have a complete runtime and
      development environment for OpenGL applications on Linux.

	<title>Linux Kernel >= 2.2.12 Required</title>
	<para>
	First of all, the OpenGL drivers for the Nvidia cards currently require
	a system with Linux kernel 2.2.12 or later.  If you don't have it, then
	you will have to upgrade your system's Linux kernel and that is the topic
	of other HOWTOs!  But nevertheless, the first step would be do download
	a new kernel at:

	<para>
        Mesa provides the foundation for the 3d support included in XFree86, which comes only
        with the libGL OpenGL core library component.  To enable hardware
        accelerated performance, many 3d hardware manufacturers provide a drop-in replacement
        for Mesa's standard software-only libGL rendering library.  For this document, we
        are only interested in NVIDIA's libGL drop-in replacement library.
        </para>

        <para>
        MesaLib provides a software OpenGL implementation consisting of libGL.  It also provides libGLU (GL Utility).
        libGLU is a library built on top of libGL to provide some higher-level functions for applications.
        OpenGL itself, libGL, is considered a low-level library. GLU is a standard part of most OpenGL
        installations and many programs make use of it.
        </para>

        <para>
        MesaDemos provides many OpenGL demo programs and, more importantly, the GL Utility Toolkit
        (libglut) library. GLUT provides a window system independent interface between OpenGL
	and any supported window system.  For instance, on the X Window System, it
	hides the details of using glX functions to setup a window.  Programmers
	can write code once and can compile it to work on MS Windows or X, etc
	provided that a GLUT library is available on the target platform. Like libGLU, libglut
        is a standard part of most OpenGL installations and is required by many programs even though
        it is not packaged with XFree86.
        </para>

	<para>
        While GLUT is bundled with MesaDemos, it is also available as a separate package from
        its original project website:
        </para>

	<para>
	glut-3.7.tar.gz

	<para>
        <ulink url="http://reality.sgi.com/mjk/glut3/">http://reality.sgi.com/mjk/glut3/</ulink>
	</para>

	<para>
        You may use *either* the GLUT included with MesaDemos (preferred and easier) or the GLUT from its
        project website.  Don't install both!  Its recommended at this time to go with the GLUT
        packaged with MesaDemos, but instructions on how to install the other GLUT are still provided
        in the next section as an option.  Note that MesaDemos does not include the glut manpages, so
        you may want to download the project GLUT package just to install its manpages.

	Qt is a cross-platform GUI library that makes it easy to create X applications
	with standard GUI elements (widgets) like menubars, scollbars, dropdown lists,
	checkboxes, buttons, multiple document interface, and many other GUI things.
	Using Qt, a program can be compiled for both MS Windows and X without
	changing any code.  Its a very popular GUI library and is used to create
	the core libraries of KDE (<ulink url="http://www.kde.org/">http://www.kde.org/</ulink>).
	</para>

	<para>
	Qt has functions (previously as an extension in $QTDIR/extensions/opengl)
        for OpenGL that provides for
	creating OpenGL rendering contexts in Qt windows.  This provides some
	alternative to both GLUT and using the glX functions directly, plus the
	added benefit of full access to the excellent qt widgets and
	cross-platform portability.
	</para>

	<para>
	This is useful if you want to compile or develop programs based on Qt
        (e.g., KDE2 and its apps).

        <para>
        Note that to install these Java files, your system needs to have glibc 2.1.3 or better.

	<para>
	Java2 1.3.0 FCS can also be used and it includes the JavaPlugin. If you use it, you
	don't have to get JavaPlugin-1.2.2-FCS.  Installation of this Plugin is different
	and you'll have to see it's docs.  Installation of Java2 1.3.0 itself, and Java3D, is
	the same as with Java2 1.2.2.
	</para>

        <para>
        The Java 3D media extension contains many 3D demo programs/applets and takes advantage of the
        OpenGL hardware acceleration on the system.  The Java 3D API uses the OpenGL API or, on Windows,
        the DirectX/3D API internally.  The demos run as normal java applications and also as applets
        inside netscape (4.7x) via the Java PlugIn!

        </para>

	<para>
	If you have a version of XFree86 installed already, you may want to move it
	or delete it.  However, installing over an existing X is generally OK and
	preserves any programs or libraries you might have installed into the X
	directories (not that you should really do that):

<sect2 id="instmesa">
	<title>Install Mesa</title>

	<para>
	Note: This gives you the libGLU* and libglut* files that are missing in XFree86.
        XFree86 only comes with the OpenGL core library, libGL (based on Mesa).  This
        also installs Mesa's libGL, but we will delete that since it is to be replaced
        by the Nvidia libGL.
        </para>

        <para>
	To completely uninstall any Mesa libs that may have come with Slackware:
	<screen>

		removepkg mesa
	</screen>
	Procedures vary for other distributions.  If there is no clear way to
	uninstall an existing Mesa, then at least confirm where it is installed:
	normally either under /usr or /usr/local.  The example below assumes that
	Mesa is installed (or going to get installed) under /usr.  Installing
	over an old version is probably harmless.  Look for /usr/lib/libMesa*
	or /usr/local/lib/libMesa* and delete them unless you have programs that
        need them.
	</para>

	<para>
	<screen>

	-- IF you are going to use the project GLUT distribution of GLUT, then
        -- unpack the Glut-3.7 packages ...
	-- Mesa's compile looks for it
	cd /usr/src
	tar -xvzf glut-3.7.tar.gz
	tar -xvzf glut_data-3.7.tar.gz
        -- IF you are using this GLUT, use the --with-glut=/usr/src/glut-3.7
        -- parameter with Mesa's ./configure below in addition to the --prefix

	<para>
	At this point, Mesa installed its own version of the glx.h include
	files over the ones that XFree86 installed.  This will cause some
	programs to fail to compile and is corrected by copying the XFree86 GL include

	vi XF86Config
		Load "glx"
		Replace 'driver "nv"' with 'driver "nvidia"'
		Put "1600x1200" first (or your preferred screen resolution)
		Copy ttf fonts from Windows into a font directory and add a font path.
                Use ttmkfdir (check freshmeat.net) to a fonts.dir file.
		A good place to keep your own fonts is /usr/local/share/fonts ...

	-- Nvidia drivers do NOT use the dri module - don't load it.

        -- You may like to edit /etc/X11/xinit/xinitrc to have run "startkde"

	<para>
	Specifying "nvidia" for the driver in the XF86Config makes that take effect
	each time you startx. But the NVdriver kernel driver will have to be
	loaded each time your system boots using:
	<screen>

		insmod NVdriver
	</screen>

        If you installed the MesaDemos package along the Mesa 3.4, then you
        have already installed GLUT 3.7 since it is included with MesaDemos.

	program that it uses to manage the Makefiles, and didn't quite see how to

        without any trouble though).  It can be done manually anyhow:

	I believe that is about it!  At this point you should have a fully functioning
	OpenGL system for running and developing OpenGL apps.
	</para>

        <para>
        You can try building the demos in /usr/src/Mesa-3.4/{demos, xdemos} by using the
        Makefile.X11 as Makefile and running "make targets" or "make teapot" etc.  They
        should build and link with the hardware accelerated libGL and run very fast!
        Qt has a OpenGL example in $QTDIR/examples/gear, that you should be able to run
        as simply as "make;./gear".
        </para>

        <para>
        Just about any standard GL/GLX/GLU/glut app should run fine, such as WolfGL, GLQuake,
        glqwcl.glx (GLQuakeWorld), quake2, and of course ... quake3!!!
