Seems like no one has much experience with this.  My only suggestion 
would be to make sure you are using the latest driver available from 
nvidia.com.  I don't know how closely the Debian package repository 
tracks the NVIDIA drivers, but the Debian-based Ubuntu ones are not 
updated very frequently.  The downside to using NVIDIA's installer is 
that you will need to reinstall the NVIDIA driver every time you update 
the Linux kernel.

     Good luck,
