Alternative to Fix Brightness Control Not Working for Kali Linux

Alternatively, you can also try using the brightnessctl command line utility to adjust the brightness. You can install it using the following command:

Open the teminal and type

It will installs the “brightnessctl” package using the Advanced Package Tool (APT) package manager on a Debian-based Linux system such as Ubuntu or Kali Linux.

To check the current brightness level

We use the following command:

brightnessctl -l

To increase the brightness level, use the following command:

brightnessctl s +10

To decrease the brightness level, use the following command:

brightnessctl s -10

Note: The BusID value in the xorg.conf.d/20-intel.conf file may vary depending on your system. You can use the lspci command to find the correct BusID value. Also, the brightness control keys may be different for your system, so you may need to modify the steps accordingly.

Other alternative, Using Brightness Controller:

Firstly, let’s add a PPA repository:

sudo add-apt-repository ppa:apandada1/brightness-controller

We added apandada1/brightness-controller from the PPA repository to the system’s software sources which contain the Brightness Controller application.

Secondly, we’ll update the package:

sudo apt-get update

Finally, we’ll install the Brightness Controller:

sudo apt-get install brightness-controller

Now, using Brightness Controller, now, we’re able to adjust the display brightness:
