how to completely remove cuda toolkit/driver from ubuntu 12.04

  • 772

I am on a Ubuntu 12.04 32bit. I have installed Cuda driver and toolkit, and now I want to remove them.

I have installed manually so they does not appear in synaptic/apt.

I have removed the driver from "Additional Driver". Well, they are inactive but still in the list. How to completely remove them?

Then, I have the toolkit in /usr/local/cuda, how to remove it completely and safely? I don't think that rm -r /usr/local/cuda is the right way..

some advice

drivers

    I just ran the installer and at the end it says

    To uninstall CUDA, remove the CUDA files in /usr/local/cuda-5.0

    So you should be fine simply removing it.

  2. According to https://help.ubuntu.com/community/Cuda (my formatting):

    "If you want to totally remove Cuda, juste delete the /opt/cuda and ~/NVIDIA_GPU_Computing_SDK folders:

    rm -r ~/NVIDIA_GPU_Computing_SDK
sudo rm -r /opt/cuda

    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.
