Kernel to upgrade to 4.4.0 Stable version installation steps

1. First download the driver package through the terminal.

2. Go to the folder
$ CD librealsense/
3. Execution under Librealsense
$ sudo apt-get update && sudo apt-get upgrade
4. Installing libsub-1.0
$ sudo apt-get install Libusb-1.0-0-dev pkg-config
5. Install the GLFW3 (installation speed is based on speeds)
$ scripts/install_glfw3.sh
6. This step is more important in the English language tutorial there are two ways to use QT and a built-in compiler I chose to bring my own compilation or execute the following code under the Librealsense folder

$mkdir build
$CD build
$cmake:
$make && sudo make install
$cmake:-dbuild_examples:bool=true
$make && sudo make install

7. Install Video4linux (kernel driver for video devices in Linux) to make sure the camera is unplugged before installation
7.1sudo CP config/99-realsense-libusb.rules/etc/udev/rules.d/
7.2sudo udevadm control--reload-rules && Udevadm Trigger

The next step is to upgrade the kernel to 4.4, which is the upgrade code.

So that the driver is loaded and then how to run the demo
8. Under the terminal, go to the Librealsense/build/examples file
$ CD Librealsense/build/examples
