How to Fix Brightness Control Not Working for Kali Linux

Step : 1 Open the terminal and create a new file using the following command:

sudo nano/etc/X11/xorg.conf.d/20-intel.conf

The sudo nano/etc/X11/xorg.conf.d/20-intel.conf command will create a new file with the name 20-intel.conf in the directory /etc/X11/xorg.conf.d/. This file is used to configure the Intel graphics driver in Kali Linux.

We can also use gedit instead of nano. Edit the file using the text editor of your choice. For example, you can use “gedit”:

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

Step 2: Add the following lines to this file:

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

Overall, this configuration snippet specifies settings for an Intel graphics device, including the driver to be used (‘intel’), the method for controlling the backlight (‘intel_backlight’), and the device’s location on the PCI bus (‘BusID’). These settings help the Xorg server properly configure and interact with the Intel graphics hardware.

Step 3: Save the file by pressing ctrl+s and come out by pressing ctrl+x and log out and log in back. The brightness control should be working through function keys now.

Step 4: Now, restart your device.
