Impressed with what I could do on my 8400 GS I just got a system with an 8800GTX, using an Xeon Dual core - running Ubuntu.
I’ve just finished installing the SDK, and when I run deviceQuery I get :
There is no device supporting CUDA.
Device 0: "Device Emulation (CPU)"
Major revision number: -1
Minor revision number: -1
Total amount of global memory: -1 bytes
Total amount of constant memory: 65536 bytes
Total amount of shared memory per block: 16384 bytes
Total number of registers available per block: 8192
Warp size: 32
Maximum number of threads per block: 512
Maximum sizes of each dimension of a block: 512 x 512 x 64

I see other people have this problem, and found clues in the nvidia installer log. I see nothing in /var/log/. This is what I get when i run ldd against deviceQuery:
