 1) Install Ubuntu 12.04.3 64-bit
 
 2) Update
 	open terminal:
 	sudo apt-get update && sudo apt-get upgrade
 	sudo shutdown -r now # reboot machine
 
 3) install compilation tools, mpi, nvidia-331 driver, gcc/g++ 4.6
    (supported, as opposed to gcc/g++ 4.8 or 4.7.3) and set as default.
    Also, install other libraries needed for CUDA Toolkit Samples compilation and make the
    respective symbolic links to where the CUDA Toolkit installer will find them:
 
 	sudo add-apt-repository ppa:xorg-edgers/ppa # adds repository that has latest NVIDIA drivers for 12.04.3
 	sudo apt-get update # updates package lists
 	sudo apt-get install build-essential libcr-dev mpich2 mpich2-doc gcc-4.6 g++-4.6 nvidia-331 # build tools, compilers, gcc, nvidia
 	sudo apt-get install libX11-dev libglu1-mesa libXi-dev libXmu-dev freeglut3-dev # libraries needed for compiling CUDA samples
 	sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.6
 	sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8
 	sudo ln -s /usr/lib/x86_64-linux-gnu/libXi.so /usr/lib/libXi.so
 	sudo ln -s /usr/lib/x86_64-linux-gnu/libGLU.so /usr/lib/libGLU.so
 	sudo ln -s /usr/lib/x86_64-linux-gnu/libX11.so /usr/lib/libX11.so
 	sudo ln -s /usr/lib/x86_64-linux-gnu/libXmu.so /usr/lib/libXmu.so
 	sudo ln -s /usr/lib/x86_64-linux-gnu/libglut.so /usr/lib/libglut.so
 	sudo shutdown -r now # reboot machine
 
 4) download & install CUDA 5.5 Toolkit 64-bit for Ubuntu 12.10 (RUN):
 	download here: https://developer.nvidia.com/cuda-downloads
 
 	install -- open terminal in directory where downloaded:
 
 	chmod +x cuda_5.5.22_linux_64.run # This marks archive as an executable, archive name might be different
 	sudo ./cuda_5.5.22_linux_64.run
 
 	# step through license agreement, then type: accept
 	Confirm you are installing on unsupported configuration -- type: y
 	Installer will ask to install NVIDIA driver -- type: n
 	Installer will ask to install the CUDA 5.5 Toolkit -- type: y
 	Installer will ask toolkit location -- default is okay, hit Enter key to select default
 	Installer will ask to install CUDA 5.5 Samples -- type: y
 	Installer will ask samples location -- this can be changed, or left to default, I chose /opt/cuda_samples and later chown'ed that directory so that all could read/write to it
 
 	Installer should complete, saying:
 
 	===========
 	= Summary =
 	===========
 
 	Driver:   Not Selected
 	Toolkit:  Installed in /usr/local/cuda-5.5
 	Samples:  Installed in /opt/cuda_samples
 
 	Next:
 
 	gedit ~/.bashrc &
 
 	and place the following lines in the file:
 
 	export PATH=/usr/local/cuda/bin:$PATH
-	export LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/cuda/lib:/usr/lib/nvidia-319:$LD_LIBRARY_PATH
+	export LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/cuda/lib:/usr/lib/nvidia-331:$LD_LIBRARY_PATH
 
 	Also add a variable in .bashrc called CUDA_SAMPLES pointing to the directory where the CUDA samples were installed from above... i.e.:
 
 	export CUDA_SAMPLES=/home/username/NVIDIA_CUDA-5.5_Samples
 
 	Lastly, to compile all the CUDA Toolkit sources:
 
 	# needed to compile samples that depend on GL
 	cp /usr/local/cuda-5.5/extras/CUPTI/include/GL/glu.h ${CUDA_SAMPLES}/common/inc/GL/
 	cp /usr/local/cuda-5.5/extras/CUPTI/include/GL/gl.h ${CUDA_SAMPLES}/common/inc/GL/
 
-	Finally, from a terminal in the directory that was chosed to install the samples type: make
+	One other thing, need to make a link to /usr/lib/nvidia-current to the driver files installed
 	by the nvidia-331 driver, as this is the location where CUDA looks for libraries in Ubuntu. Do this via:
 
-	For platforms with Optimus (laptops) refer to: http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html
+	sudo ln -s /usr/lib/nvidia-331 /usr/lib/nvidia-current
 
 	Finally, from a terminal in the directory that was chosen to install the samples type: make
 	All the samples should compile successfully.
