Fix Brightness on Ubuntu 14.04 LTS & Mint 17(Intel Video Card)

Have you ever tried to control brightness on you Linux PC/Laptop? If the answer is yes, then you may have been failed to do so!! I too just failed to control brightness on my Ubuntu 14.04 LTS laptop for many times after applying so many methods. They just didn’t work out. I was searching for a technique for controlling the screen brightness and finally I have got one! Now I am sharing this to you. I applied this on Ubuntu 14.04 LTS and Linux Mint 17 and it worked. I don’t know whether it works on other version or not. You may try.

Now let’s go to the tasks that you have to do.
Firstly open the terminal (Ctrl+Alt+T) and then copy and paste the code to the terminal and press enter.

sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf

This will create a configuration file. Now we will have to edit this file. To do edit, we will have to enter the following code to the terminal

sudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf

This will open a configuration file. Now you will have to copy and paste the following lines to the configuration file.

Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"EndSection

Now save the configuration file and then close it.
Log out and log in back. The brightness control should be working through function keys now.
Isn't it pretty cool!!!??? Happy Linuxing.
