CUDA 7.5ΒΆ

1. Download your relevant CUDA.run file, e.g. cuda_7.0.28_linux.run. Note, that once again this install is if you purely want to use your graphics card (Titan X) for GPU/CUDA purposes and not for rendering.

2. Run:

sudo apt-get install build-essential

3. No need to create an xorg.conf file. If you have one, remove it (assuming you have a fresh OS install):

sudo rm /etc/X11/xorg.conf

4. Create the /etc/modprobe.d/blacklist-nouveau.conf file with : blacklist nouveau option nouveau modeset=0

Then:

sudo update-initramfs -u

5. Reboot computer. Nothing should have changed in loading up menu. You should be taken to the login screen. Once there type: Ctrl + Alt + F1, and login to your user.

6. Go to the directory where you have the CUDA driver, and run:

chmod a+x .

7. Now, run $ sudo service lightdm stop The top line is a necessary step for installing the driver.

8. Run the CUDA driver run file. *Notice that I explicitly don’t want the OpenGL flags to be installed:

sudo bash cuda-7.0.28_linux.run –no-opengl-libs

9. During the install:

Accept EULA conditions
Say YES to installing the NVIDIA driver
SAY YES to installing CUDA Toolkit + Driver
Say YES to installing CUDA Samples
Say NO rebuilding any Xserver configurations with Nvidia.

10. Installation should be complete. Now to check if device nodes are present, check if /dev/nvidia* files exist. If they don’t exist:

sudo modprobe nvidia

11. Set Environment path variables:

export PATH=/usr/local/cuda-7.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-7.0/lib64:$LD_LIBRARY_PATH

*Change depending on your cuda version.

12. Verify the driver version:

cat /proc/driver/nvidia/version

13. Check CUDA driver version:

nvcc -V

[Optional] At this point you can switch the lightdm back on again by doing:

sudo service lightdm start

You should be able to login to your session through the GUI without any problems or login-loops.

14. Create CUDA Samples. Go to your NVIDIA_CUDA-7.5_Samples folder and type make.

15. Go to NVIDIA_CUDA-7.5_Samples/bin/x86_64/linux/release/ for the demos, and do the two standard checks: ./deviceQuery to see your graphics card specs and ./bandwidthTest to check if it is operating correctly.

Both tests should output a β€˜PASS’ in your terminal.

16) Reboot.
