If the monitor buttons aren't working, you find them difficult to use, or the buttons aren't available, use the next two methods. We would suggest you read your monitor's instruction manual to know how to access the customization menu. The on/off power button also acts as a controller on certain monitors. On some monitors, you will find a tiny joystick at the bottom of your monitor that can be used to access the menu and eventually control the brightness and other parameters. You can control different monitors in different ways. The first method involves taking the help of button controls on your monitor itself to change the brightness. These solutions will also come in handy if you are using a multi-monitor setup. That's where the following methods will help.

You should skip the two lines xinput if not needed (or adapt ).įor the value 4000, it may be diffrent for each screen, you should first see what is your max value with the command cat /sys/class/backlight/intel_backlight/max_brightness Note that xinput is just a command for my trackpad to set the middle button working.
