[CVALE] 3D in Ubuntu

[Terry]

Greetings,

I loaded Ubuntu on someone's desktop so they could try Linux.  It seems 
to work okay.  The wireless even worked once we swapped out a newer 
Netgear PCI card for an older one.

I'm having trouble getting the video drivers working for the Nvidia 
GeForce 7800GT card however.  lsmod shows either the default "nv" driver 
or the Synaptic installed "nvidia" driver after I modify the 
/etc/X11/xorg.conf file.

When I run glxgears though it's just a cpu running at 99% that's 
rendering the graphic.  Also glxgears is NOT giving the fps numbers.
When I purposely make a mistake in the xorg.conf file X11 complains so I 
believe Ubuntu uses that path.

What am I doing wrong?  Is there another simple test for the 3D 
acceleration other than glxgears?  Do I need to pull the Nvidia web site 
file down because there's a problem with the Ubuntu binary driver.

We're running the current desktop Ubuntu release pulled from the Ubuntu 
site (or a mirror) about 10 days ago (6.06).  We also updated to the 
newest kernel ( -25) available with an Ubuntu update via the Synaptic 
manager.

This is a dual boot machine and the video card works fine in MSXP-SP2.

Although I've never cared for point-and-click distributions in the years 
past I'm giving this one a try and it mostly works on the target hardware.

Thanks for your help.

Terry
