How to enable Brightness key in Fedora?

Issue

By default brightness key in your laptop won't function properly with Fedora. For example F6 will be your brightness decrease and F7 will be your brightness increase. While pressing F6 or F7 you may see a bar but there won't be any change in brightness.

Solution 

To make it function properly you need to switch to root user and enter the below two commands

mkdir /etc/X11/xorg.conf.d

echo -e ' Section "Device"\n\tIdentifier  "Intel Graphics"\n\tDriver      "intel"\n\tBusID       "PCI:0:2:0"\n\tOption      "Backlight"       "intel_backlight"\n EndSection' | tee /etc/X11/xorg.conf.d/20-intel.conf




Copy paste both commands to your terminal enable brightness key. The brightness is not working because the above configuration file was missing. This file will manages the changes in your display, video card etc.
