CUDA-Multiforcer will not work although CUDA Toolkit and everything is installed

Question

I installed everything like here on my new Ubuntu 11.10 Desktop.

Specifications:

• Intel core i5 2500k,
• 16 GB RAM,
• NVIDIA GeForce GTX 560TI CU II by ASUS

So I installed everything but the CUDA-Multifocer says:

This program requires a CUDA-capable video card.
No cards found.  Sorry.  Exiting.

The output of nvidia-smi:
