Solution: Finaly i solved my problem!!!
sudo apt-add-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-current nvidia-settings
i have no idea how i can solve this issue.
I tried already some advices from internet, but without success.
I use this way to setup nvidia and CUDA.
So this i get, if i type optirun glxgears
[ 115.282141] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Failed to load module "nvidia" (module does not exist, 0) [ 115.282190] [ERROR]Aborting because fallback start is disabled.
This is my bumbleblee.conf
