   Driver: Installation Failed


You may find this error message while trying to set up the NVIDIA CUDA Toolkit in Ubuntu.

I found it when I was installing the toolkit for ArrayFire


[1] CUDA Toolkit Installation

1. Download the CUDA Toolkit in the link

2. Extract the .run file in a location

   sudo sh --extract <location>


3. Exit the X server (press Ctrl+Alt+F1) and stop the display manager by the following command.

   sudo stop lightdm


4. cd to the location and now there are run files named samples*, devdriver* and cudatoolkit*.

5. Install devdriver (*only if NVIDIA Driver is not installed)

   sudo sh


6. Install cudatoolkit

   sudo sh

In the end, when it asks “Would you like to create a symbolic link /usr/local/cuda/ pointing to /usr/local/cuda-x.x?”, you must enter (y)es.

If it didn’t ask, or you didn’t enter (y)es, enter the following command to create a symbolic link.

   ln -s /usr/local/cuda-x.0 ./usr/local/cuda


7. Install sample (*optional)

   sudo sh


8. Reboot your machine

   sudo reboot



[2] ArrayFire Installation

1. Create AccelerEyes account to download ArrayFire

2. Unzip arrayfire in /usr/local

   sudo unzip ArrayFire*.zip -d /usr/local



[3] Environmental Variables Setting

 1. Open bash setting

   vim ~/.bashrc


2. Add the following lines in the end (probably only need to set LD_LIBRARY_PATH)

   export AF_PATH=/usr/local/arrayfire
   export CUDA=/usr/local/cuda
   export PATH=/usr/local/cuda/bin:$PATH
   export LD_LIBRARY_PATH=/usr/local/cuda/lib:/usr/local/cuda/lib64:/lib64:$LD_LIBRARY_PATH


3. Reload bash setting

   source ~/.bashrc


Note: This may not work in laptops with optimus
