VMD-L Mailing List

Hi,

I tried the new NVidia drivers on desktop machines running redhat linux 8.0 with a Ti4200 and a QuadroXGL card, and they worked fine. The problem with the resize is limited to the 'mobile' chip. I will check the NVidia mailing list to check if that needs some specific adjustment.

By the way, I would be interested in trying the special version for Stereo. As I mentioned, we now have a machine with NVidia Quadro750XGL, plus NuVision shutter glasses, but I experienced the same problems mentioned by other people when trying the stereo visual, just the above/below scene with no real stereo.
If you could email me the location of the download for testing I'd be very grateful.

Thanks for the attention and the wonderful program.

Today I upgraded to their latest release, 1.0-4363 (24/04/2003) and vmd just takes up 99% of the CPU when resizing an empty window. The system no longer freezes but the program is not usable... I think the drivers might need some more bug-fixing. Next week I will test them on a machine running redhat8.0 with basically the same graphic card (NVidia Ti4200) where I happily run VMD with older drivers and I will let you know the outcome.
