Bug#795262: nvidia-cuda-toolkit: Reboot, after package installation, do not unload the Nouveau drivers

[François Legendre]

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.

Regards,
----
François
