in the system-> details i see "Intel® Haswell Mobile" in the graphics.
i want to install cuda.
i downloaded cuda-repo-ubuntu1404_7.0-28_amd64.deb from developer.nvidia.com/cuda-downloads
i followed the next link github.com/facebook/fbcunn/blob/master/INSTALL.md and did:
sudo apt-get install build-essential
sudo dpkg -i cuda-repo-ubuntu1404_7.0-28_amd64.deb sudo apt-get update
sudo apt-get install cuda
echo "export PATH=/usr/local/cuda/bin/:\$PATH; export LD_LIBRARY_PATH=/usr/local/cuda/lib64/:\$LD_LIBRARY_PATH; " >>~/.bashrc && source ~/.bashrc
then when i reboot the computer, the laptop gets stuck with the ubuntu logo just before login.
why is that? i tried to understand why is that, and got confused.
do i need to install nvidia drivers before doing so, or does cuda install kit already includes it?
i tried to install the drivers using ppa-xorg edgers following this link http://www.binarytides.com/install-nvidia-drivers-ubuntu-14-04/ .
i managed to install the drivers, and reboot. and then tried to install cuda again the same way and got the same problem.
or is it because i have hybrid gprahic, both intel and nvidia? if so i can fix it?
each time it happens, i end up reinstalling ubuntu.
i only care about getting cuda working.
