Backbox setup for Nvidia CUDA without using Nvidia as default driver (X11) but Intel/Nouveau and fix possible issues.

backbox_cuda.md

Setup virtualgl/nvidia/bumblebee

• Setup last virtualgl (dl last stable version like 2.5 at http://sourceforge.net/projects/virtualgl/files/ )

dpkg -i virtualgl*.deb

• Setup bumblebee for nvidia :

sudo apt-get install linux-headers-$(uname -r) freeglut3-dev libxmu-dev libpcap-dev bumblebee-nvidia primus

• Setup via additional drivers UI Nvidia latest/tested version (352.69 currently)

• Configure bumble bee :

  in /etc/bumblebee/bumblebee.conf : Driver=nvidia and replace all lines with nvidia-current with your nvidia version (e.g nvidia-352)

  then

  sudo service bumblebeed restart

• Setup nvidia-modprobe sudo apt-get install nvidia-modprobe (auto module loader for non-root users) and nvidia-prime sudo apt-get install nvidia-prime

Setup cuda

• Download cuda 7.5 (.run mode, and answer no to "setup NVIDIA driver 3XX ...") and NEVER use nvidia driver for X11 server (use sudo prime-select intel if you need to disable nvidia)

• Add to your PATH env variable : /opt/VirtualGL/bin:/usr/local/cuda-7.5/bin

• Add to /etc/ld.so.conf : /usr/local/cuda-7.5/lib64 then run sudo ldconfig

• Add lines to file at startup (e.g /etc/rc.local)

NVIDIA_VERSION=352
update-alternatives --set x86_64-linux-gnu_gl_conf /usr/lib/nvidia-$NVIDIA_VERSION-prime/ld.so.conf
update-alternatives --set i386-linux-gnu_gl_conf /usr/lib/nvidia-$NVIDIA_VERSION-prime/alt_ld.so.conf
prime-select intel

• Now reboot your laptop

Test Cuda

• Then you can test your CUDA setup :

cd ~/NVIDIA_CUDA-7.5_Samples/1_Utilities/deviceQuery
make
optirun ./deviceQuery

• How to use with cudaHashCat64 or another runnable compatible with CUDA ?

alias cuda='optirun --no-xorg'

#then:
cuda ./cudaHashCat64 -b

Ignore update of packages (because we don't need upgrades) :

1. search nvidia installed packages : sudo dpgk --get-selections | grep 'install' | grep 'nvidia'
2. search libcuda installed packages : sudo dpgk --get-selections | grep 'install' | grep 'cuda'
3. for each, mark hold in apt : sudo apt-mark hold <package>
