Hello, I installed only the nvidia-cuda-toolkit using synaptic on the top of a fresh Debian 8 distribution on a Dell Precision M 4700 station (with a Quadro K2000M graphics card). I though that the Debian distribution installed the nouveau drivers. I do not used any Nvidia installers. I used the nvidia-cuda-toolkit package 6.0.37-5 from the jessie distribution. I do not used the new nvidia-cuda-toolkit from the experimental distribution.
