Hello,

I have ACER with GeForce GT640m on my notebook. I installed bumblebee, and it works perfectly. But I have the problem with CUDA, it does not want to work with pyrit or hashcat.They cannot find the device. There is nvcc from /urs/bin

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2012 NVIDIA Corporation
Built on Thu_Apr__5_02:05:07_PDT_2012
Cuda compilation tools, release 4.2, V0.2.1221

I am trying to solve this problem for 3 days, but did not find anything. Thank you for your help.
