Fix Brightness Control Not Working for Kali Linux
Brightness control issues can be frustrating when using Kali Linux, an operating system. Changing screen brightness on Kali Linux can be tricky sometimes. Brightness control is important for user comfort and saving battery life. But different things like hardware, drivers, and settings may cause issues. The brightness may not work properly due to these factors -> compatibility, drivers, and system configurations can affect brightness control functionality.
In this guide, we will learn how to fix brightness issues on Kali Linux. We will start with easy steps like system updates. Then we will move to harder steps for changing settings. By the end, you should control the brightness on your laptop or desktop. No matter if you use Kali Linux on a laptop or computer, these steps can help fix brightness problems.
PROBLEMS
Problems related to brightness in Kali Linux could encompass a variety of issues. Firstly, the screen’s brightness might appear too dim, making it challenging to view content clearly. Sometimes, the brightness settings may not respond, preventing adjustments. Additionally, the brightness level could fluctuate unexpectedly, causing discomfort and eye strain.
- Screen Brightness Control Not Working: Some computer users have a problem. They cannot change the brightness of their screen. The keys on their keyboard do not work for this. Also, the computer programs do not have controls for brightness.
- Brightness Settings Not Persistent: When you change the brightness, it might not save. Or it might go back to the normal setting when you restart the computer. The brightness settings may get lost. Sometimes, they don’t stay changed after a restart.
- Incorrect Brightness Levels: The screen may seem too dark or too bright. This problem remains even after you change the brightness settings. The levels might not be right for you.
- No Brightness Control Options: Users might find that there are no options available to adjust the brightness in the system
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.
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
sudo apt-get install brightnessctl
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:
