HOW-TO install the latest nvidia 319.23 drivers

After spending a lot of time trying to figure this out, I could finally make it without HDMI external output connected. The original Nvidia documentation needs to be tweaked for the 319.23 to actually work (intel instead of modesetting driver + autologin)

Install kernel 3.9

Download the latest 3.9 kernel files from the mainline and put them in a same folder :

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/linux-headers-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/linux-headers-3.9.0-030900_3.9.0-030900.201304291257_all.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/linux-image-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb

sudo dpkg -i *.deb

Add xorg-edgers amd Canonical X-Staging PPAs

sudo add-apt-repository ppa:canonical-x/x-staging
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install xserver-xorg-video-intel

Open Synaptic Package Manager and lock version (click on package then Package/Lock Version) of xserver-xorg-input-synaptics (should be version 1.6.3-0ubuntu1.1)

sudo add-apt-repository ppa:xorg-edgers/ppa 

sudo apt-get update && sudo apt-get upgrade

Install latest nvidia driver and create xorg.conf / .xsessionrc

sudo apt-get install nvidia-319

sudo vi /etc/X11/xorg.conf

Section "ServerLayout"
    Identifier "layout"

EndSection

Note : Your BusID can be obtained by running lspci | grep -i nvidia

sudo vi ~/.xsessionrc

xrandr --setprovideroutputsource Intel NVIDIA-0
xrandr --auto

Compile and install xrandr 1.4 from source

sudo apt-get install mesa-utils xutils-dev libxrandr-dev automake synaptic gksu
wget http://cgit.freedesktop.org/xorg/app/xrandr/snapshot/xrandr-1.4.0.tar.gz 

tar -xzvf xrandr-1.4.0.tar.gz

cd xrandr-1.4.0/

./autogen.sh

make

sudo make install

Add autologin feature in lightdm

sudo /usr/lib/lightdm/lightdm-set-defaults --autologin <username>

REBOOT and enjoy !!!

Add glxspheres to benchmark

wget http://ftp.jaist.ac.jp/pub/sourceforge/v/project/vi/virtualgl/VirtualGL/2.3.2/virtualgl_2.3.2_amd64.deb

sudo dpkg -i virtualgl_2.3.2_amd64.deb 

/opt/VirtualGL/bin/glxspheres64

P.S. : Thanks to @pogopuschel for providing the initial HOW-TO that I adapted according to my experience.

Note : after installing this driver the tap to click feature of the touchpad is not working anymore. It seems to be related to the version of the xserver-xorg-input-synaptics package (1.6.99+git20130104.ce7565ea-0ubuntu0sarvatt). If someone finds a way to fix it please share.

UPDATE 04/06/2013 : I found a way to fix the touchpad issue => see purple section above ! Cheers !
