I am able to download and install the video nvidia driver NVIDIA-Linux-x86_64-331.38.run  , but cudaminer still fails with "Unable to query CUDA driver version! Is an nVidia driver installed?"   If I try and install the cuda driver by its self, I fail with ->   http://bpaste.net/show/p05x0p0zanBaXUPa3rmL/

even sgminer is unable to see my graphics gpu:

 sgminer -o stratum+tcp://mine.validerrorpool.com:3340 -u tunage -p 1 -q

[2014-02-15 18:03:04] Unable to query CUDA driver version! Is an nVidia driver installed?

the problem isn't cudaminer related. it seems an Ubuntu problem. Perhaps you must download Tesla drivers, not generic videocard ones.

I had better experience with Mint or Suse than I ever had with Ubuntu.
Does it work on Windows?

The drivers are from nvidia directly  https://developer.nvidia.com/cuda-downloads   (which doesn't work)  and http://www.nvidia.com/Download/driverResults.aspx/72250/en-us   (which does install, but useless to cudaminer).
I wouldn't touch windows.

Good luck, then.

Windows is never a solution and should never be used as a server.
