Hi, Peter. 


   Thanks for that reply. I somehow didn't think to try the XLIB flag again, as I thought that issue had been fixed in the later Mathematica builds (used to use it all the time). In any case, it doesn't seem to work for me (3D plots still disappear except upon rotation, and ColorFunctions still cause blank output). As you say, it might be the opensource driver. AMD/ATI are having such problems that they no longer provide any new proprietary drivers for their older cards -- it's causing headaches in the community, obviously.
   When I try the XLIB... export, Mathematica shows many "holes" in the Plot3D graphs, and the rotations are much slower and jerkier than usual. I guess I'll just live with the state of things as they are now, until Mathematica learns to work with the drivers, or the driver writers can agree on a unified front (ha!). 

       Thanks again!
                     Curtis O.
