Ubuntu 14.04 how to install cuda 6.5 without installing the nvidia driver

Question

I work on a workstation with an I7 4790 processor core and two GTX 760 GPUs 4 GB RAM / 1152 core, system memory 16 GB RAM I have Ubuntu 14.04.1 LTS after many attempts and reinstalling Ubuntu many times, finally, I installed the driver correctly nvidia 340.46 using three shell commands ppa xorg-edgers

Now I want to install the Cuda 6.5 toolkit but in the manual they say that the cuda toolkit installer will also install the nvidia Graphics driver

how to prevent the installer from installing the graphics driver, how to install cuda 6.5 toolkit without reinstalling my graphics driver, because I ran into many problems until I installed correctly 340.46

and after successful installation of cuda toolkit 6.5 how to update the graphics driver without violating the cuda toolkit and reinstalling everything from the very beginning

Answer 1

If you use the profile installation method , the tool installer will ask you separately for each of the three components:

• GPU driver
• CUDA Toolkit
• CUDA Samples

Therefore, use the run installer method and simply select “no” at the first prompt if you do not want to install the driver. You can still install the toolbox and samples. You can download the runfile installation file from here.

and after successful installation of cuda toolkit 6.5 how to update the graphics driver without violating the cuda toolkit and reinstalling everything from the very beginning

The driver can always be installed separately by downloading the driver installer package from www.nvidia.com.

If you use the package manager method, it should be possible to install a toolbox without a driver by installing the cuda-toolkit-XY package, where XY is the version of CUDA. See the package manager section of the installation guide.
