===== How to install cuda toolkit 3.2.16 and lastest Nvidia drivers (260.19) from Ubuntu Lucid 10.04 x86-64 =====

The version 3.2.16 of cuda toolkit version requires driver 260.19 from Nvidia. To add this Nvidia driver version from a ppa source, we need to write from a console:

<code bash>
$ sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
$ sudo apt-get update
$ sudo apt-get install nvidia-current nvidia-current-modaliases nvidia-settings
</code>

We configure the X to use the new drivers:

<code bash>
$ sudo nvida-xconfig
</code>

Now reboot the machine to take effect the changes made:

<code bash>
$ sudo reboot
</code>

To obtain cuda toolkit 3.2.16 press here and download it inside /tmp, then execute:

<code bash>
$ cd /tmp
$ chmod 755 cudatoolkit_3.2.16_linux_64_ubuntu10.04.run
$ sudo ./cudatoolkit_3.2.16_linux_64_ubuntu10.04.run
</code>

When it asks about path where it'll install, we enter the default location (/usr/local/cuda). After cuda toolkit finish, we create a file called /etc/ld.so.conf.d/cuda.conf with the next content:

<code bash>
$ cat /etc/ld.so.conf.d/cuda.conf
/usr/local/cuda/lib64
/usr/local/cuda/lib
</code>

We need execute ldconfig to include dynamic libraries from cuda toolkit:

<code bash>
$sudo ldconfig
</code>

To finish, we need to give permissions to access the folder /usr/local/cuda

<code bash>
$ chmod -R 755 /usr/local/cuda
</code>
