[FIX] Brightness Keys Not Working on a Notebook/Laptop - Ubuntu/Linux Mint

In this tutorial, we will see a solution that may render your brightness keys workable again in a laptop/notebook running Ubuntu/Linux Mint.

Before starting, you should bear in mind that this solution is not meant to fix all laptop or notebook models and is dedicated for users of intel cards for adjusting brightness levels. Also, this tip is only workable on Ubuntu/Linux Mint with GRUB 2.

Getting Started

You can check if you have an intel card by running this command:

 ls /sys/class/backlight/

If the returned outputs show this:

(...) intel_backlight

Then this solution may work for you. In the same terminal window, enter this command:

sudo gedit /etc/default/grub

Find this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change it to this one:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

Save your file and exit, then run this command to update GRUB 2:

sudo update-grub

Finally, reboot your system.

Good luck!

Rebellin Linux 1.5

Utkarsh Sevekar has announced the release of Rebellin Linux 1.5, a set of commercial, desktop-oriented distribution based on Debian "Stable" (the "Synergy" edition) and Debian "Unstable" (the "Adrenalin" variant): "It gives us immense pleasure to announce the latest Rebellin Linux release - version 1.5.
