a month ago I installed the cuda 5.5 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 new cuda 6.5 toolkit,

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

I get the following:

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

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

Thanks

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

recently I wanted to remove Cuda from my Ubuntu, I founded there is a prepared file for doing this!! (I guess this method is standard one)

first of all change directory to cuda path,which in default it is /usr/local/cuda-9.0/bin, you can change the directory with using the below command:

 cd /usr/local/cuda-9.0/bin

in the directory there is a file which it's name is uninstall_cuda_9.0.pl(please pay attention that my cuda version is 9.0) , so you just need to run uninstall_cuda_9.0.pl to remove cuda completely from your system!!

sudo ./uninstall_cuda_9.0.pl

After entering your password the cuda files are going to earase . ( it may take a few minutes to complete)

NOTE: How to know which cuda has installed on my ubuntu?
You could check this thing by the nvcc command, as you can see in the last line of the result our cuda version is 9.0

nvcc --version

result of this command will be like as below:

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Sep__1_21:08:03_CDT_2017
Cuda compilation tools, release 9.0, V9.0.176

Make sure the method you use to install cuda toolkit. This answer is for whom use deb files to install cuda. I have no idea if this works for .run files.

sudo apt-get autoremove --purge cuda 

This can clear the cuda toolkit clearly. You can check that the folder /usr/local/cuda gone. And this command is the best choice to remove apt installed app.

But when you reinstall another version of cuda, you must use:

sudo apt-get install cuda-x.x

the version number must be included. I tried to install another version of cuda after the remove of the previous version, I find that sudo apt-get install cuda will still install the previous one.
