NVIDIA Quadro 2 Pro - except for the crashes, it is really great, the graphics
has
a "look and feel" of SGI, but everything is faster.
the other crashing machine has NVIDIA GeForce

I have had dri disabled all the time, so that is not a problem for me.
We have also tried to run it on a single processor - it crashes too but at
least
it gives an error message.
Bob, I put my Xconfig and log file from the crash at
http://bathy.meas.ncsu.edu/grasswork/XF86Config-4
http://bathy.meas.ncsu.edu/grasswork/XFree86.0.log

maybe you will see something obvious there that we are missing.
I don't have any problems with rendering or any other NVIZ functionality.
the crashes happen when the interface window is being opened or when I
am closing it.

thanks for looking at it,

Helena
