Gordon, getting everything right is damn near impossible. Thank your own
deity that Branden has done most of the work for us already. :)
Currently, I don't use libGLU, but copying the one libGLU library out of
the package is probably sufficient.
What I have found about getting my g400Max to do GLX is that it requires
using XFree86's mga_drv.o driver, loading the agpgart and mga kernel
modules (I use 2.4.0-test10 with good success, and perhaps
2.2.18-presomething would have the same effect, but that may require
kernel drivers from dri.sourceforge.net) and having the right mix of
packages installed. I don't think it takes any of the mesa packages.
To get the g400Max to do dual-head requires using matrox's mga_drv.o
file. I'm not sure if agpgart and mga need to be unloaded or not from
the kernel, but I do, to save memory.
You will also need to tweak your XF86Config-4 file to load the glx, dri,
GLCore, and dbe modules. (I have two config files, one to describe both
monitors, one to describe only one monitor, and I switch between the two
when I want GL to work.)
Yes, it is a bit annoying, but not enough to cause me to learn how to
program these things for the accelerated OpenGL while running dual-head.
