NvAgp options 2 or 3 result in Xsession lockups when I run glxgears.
Options 0 or 1 exhibit no such hangs.

This has all helped at least in that I've learned a lot. Perhaps agpgart is a 
problem due to the fact that the system was installed with a pci vidio card 
and agpgart is not configured correctly?
	One more question if you don't mind: After taking your advice to this point, 
I seem to have a fairly stable X configuration. My last problem is that fast 
zooming with my scroll wheel in my Pro_Engineer application sometimes crashes 
it. No more X session crashes, butloosing data can be a bit aggrevating. Are 
there options that can be set for my logitech Marbleman+ trackball? It is 
configured as protocol "IMPS/2"
