Ubuntu – Removing Nvidia CUDA Toolkit and installing new one

bumblebeecudadriversnvidiauninstall

I installed the CUDA 5.5 package on Ubuntu 14.04 (which is not supported for this version of Ubuntu version) , and I didn't do it well.

I want to remove what I've installed earlier and install a new CUDA 6.5 toolkit,

After typing this in the terminal: dpkg -l | grep -i nvidia,

I get the following output:

I'd like to remove only what is needed to install the newest CUDA toolkit. Packages, like bumblebee, I want to remain as they are.

Which packages should I remove and which should not be removed to get this done?

Best Answer

This method will give a complete removal of Cuda:

Simple

remove the CUDA files in /usr/local/cuda-5.0

Advanced

Uninstall just nvidia-cuda-toolkit

sudo apt-get remove nvidia-cuda-toolkit

Uninstall nvidia-cuda-toolkit and it's dependencies

sudo apt-get remove --auto-remove nvidia-cuda-toolkit

Purging config/data

sudo apt-get purge nvidia-cuda-toolkit or sudo apt-get purge --auto-remove nvidia-cuda-toolkit

Additionally, delete the /opt/cuda and ~/NVIDIA_GPU_Computing_SDK folders if they are present. and remove the export PATH=$PATH:/opt/cuda/bin and export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib:/opt/cuda/lib64 lines of the ~/.bash_profile file
