this is the first few lines of glxinfo, I could not figure out which is
the line that tells me the driver. I can post the whole results from
glxinfo if necessary. There seem to be linux drvivers available from
intel, but I can't figure out how to install them. The computer is a
Dell Dimension B110 that originally had XP home on it, and the only
drivers available from dell appear to be windows drivers.
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes

the kernel is easy enough to determine(ithink) : 2.6.28-15-generic
I could not really figure out how to determine what version of
X-windows I have.

I have to say that I don't have much experience of intel graphics drivers, as
I have had either nVidia or AMD (back then ATi) graphics cards, the later one
only with open source drivers as that one been used on other architectures
than x86.
If I don't remember it wrong, there been from time to time some bad intel
drivers in X, check which version of X you are having and google for some
info, to see that the driver isn't broken and that you don't have some options
which may not be good with the current combination of driver/graphic.

This apply only to AMD and nVidia drivers, as they ship modified X11 libraries
and a kernel module. Using the intel driver, which is just a kernel module.

According to GLXINFO, the glx version 1.2, and the Open GL version
string is 2.1 mesa 7.4. I have no idea if either of these is the
version of X that I am running or how to determine that.
I wonder if this page might help:

It seems you are using the software opengl, with other words your opengl isn't
hardware accelerated but computed by the cpu.
I think it can be a good idea to try to follow the steps there.
