# You will need latest NVIDIA drivers installed. At the time of writing, version is 331.20.
# On ubuntu 13.10, it looks like this:
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-331

# Now we need to install bumblebee:
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get install bumblebee bumblebee-nvidia bbswitch-dkms

# Reboot

# Intel-virtual-output tool

# First, you will need latest xf86-video-intel driver installed (2.99). Ubuntu 13.10 comes with it,
# so you don’t need to update driver in that case. However, what made all of this possible is the
# latest release of intel-virtual-output tool, which comes bundled with xf86-video-intel driver
# source. But, ubuntu’s package does not bundle it, and we need to compile it from source. One
# MAJOR thing to note here is: DO NOT compile it from ubuntu’s deb-src package. That package is old,
# and current release has some major fixes for the tool that we will actually need in order to have
# everything working properly. So lets do it:

sudo apt-get install xorg-dev git autoconf automake libtool
cd /usr/src
git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-intel
cd xf86-video-intel
./autogen.sh
cd tools
make
sudo cp intel-virtual-output /usr/bin/
sudo chmod +x /usr/bin/intel-virtual-output

# Install scripts listed in this Gist and augtool:
sudo vim /usr/local/bin/nvidia-enable
sudo chmod +x /usr/local/bin/nvidia-enable
sudo vim /usr/local/bin/nvidia-disable
sudo chmod +x /usr/local/bin/nvidia-disable
sudo mkdir -p /etc/bumblebee/dual-monitor
sudo vim /etc/bumblebee/dual-monitor/enable.aug
sudo vim /etc/bumblebee/dual-monitor/disable.aug

sudo apt-get install augeas-tools

# Done, now enable external monitors with: `nvidia-enable` and disable with `nvidia-enable` command
