Hello,
  I've recently installed VMD on a Ubuntu 8.10 system and followed the
install directions in ig.pdf. I have most things working now, thanks to
help on this site. However, at start up I get the following message.

The default configure file detects my NVIDIA Quadro NVS 135M card which
is CUDA capable--albeit a low end card (256MB RAM--interesting that VMD
says 127MB...)
and then says that no CUDA device is available...

There are 2 warnings related to X11 'composite' extension which I don't
know if they are related to the CUDA issue.

I did check that my CUDA and video drivers are upto date per this thread
http://www.ks.uiuc.edu/Research/vmd/mailing_list/vmd-l/13983.html

I have CUDA 2.3 installed with Driver version 190.18.

Thanks in advance.
