Hi, all-

I have a Sony VAIO 13" laptop with an NVIDIA GeForce GT 330M video card (with "CUDA", whatever that means). Running 64-bit Natty, the free experimental 3D driver works, but I can't seem to get the proprietary one to play nicely. I remember it working with Natty Alpha 2, but with Natty final, it forces Ubuntu into Classic (GNOME desktop) mode.

My reason for wanting to use the proprietary driver is that the free one doesn't seem to be accelerating much. The proprietary one was much smoother, back when it worked.

Thanks in advance for any light you can shed!
