Install new NVIDIA graphics card and cuda on Linux Mint

NVIDIA driver

Manual install instructions from https://sites.google.com/site/easylinuxtipsproject/12

• Power off
• Install card in motherboard slot
• Connect monitor cables to card outputs
• Find out what graphics card you have: $ lspci | grep VGA
• Find out which driver you should download by entering card details at: http://www.nvidia.com/Download/index.aspx?lang=en-us
• Download the driver
• Remove all previous nvidia drivers by running: $ sudo apt-get purge nvidia*
• $ chmod +x -v ~/Downloads/NVIDIA-Linux-*.run
• Switch to terminal only mode: $ sudo service mdm stop
• Login in terminal-only mode
• Run: $ sudo sh ~/Downloads/NVIDIA-Linux-*.run
• Accept all options
• After everything is done, $ sudo reboot
• Did it work?
• Everything should display properly in high res
• $ lsmod | grep nvidia
• $ lspci | grep VGA
• Check if nouveau is still being used (if properly installed, no), by: $ lsmod | grep nouveau

If things didn't go to plan, and you need to uninstall, then:

$ sudo sh ~/Downloads/NVIDIA-Linux-*.run --uninstall

$ sudo rm -v /etc/X11/xorg.conf

$ sudo reboot

CUDA

Again, prefer manual install from https://developer.nvidia.com/cuda-toolkit-archive over official repository cuda packages. Use the run file instructions from http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/#axzz45oaAPyTF. Don't accept offer to reinstall Nvidia drivers during cuda installation.

Run install_IDT_code.sh, but this will run into errors at first. Follow the instructions given in install_IDT_code.sh to edit Makefile. That should do the job.

The code snippet in https://gist.github.com/dineshj1/d6b975a8d3d160e95c69 should be added to the end of the .profile file.
