I am trying use CUDA under Ubuntu 11.04 and Mathematica 8. However the command:
GPUTools`Internal`$NVIDIADriverLibraryPath fails. I added:
export NVIDIA_DRIVER_LIBRARY_PATH=/usr/lib/nvidia-current to .bashrc, but that didn't help. Any thoughts ? My card is a NVIDIA GeForce GT 420 and otherwise works fine under Ubuntu.
