backlight_control Command Examples in Linux

by admin

backlight_control is a command-line tool in Linux that is used to adjust the backlight brightness of a display. The backlight is a light source that is used to illuminate the display of a device, such as a laptop or smartphone, and is typically controlled by a hardware component called a backlight controller.

backlight_control can be used to increase or decrease the brightness of the display by adjusting the intensity of the backlight. It can be used to set the brightness to a specific level or to adjust the brightness relative to the current level.

To use backlight_control, you will need to have the appropriate permissions to access the backlight controller on your system. This typically requires root privileges or access to the appropriate device file in the /sys/class/backlight directory.

The exact syntax and options for backlight_control may vary depending on the specific implementation and configuration of the tool. In general, you can use the backlight_control command followed by the desired brightness level or adjustment. For example, to set the brightness to 50%, you might use a command like this:

# backlight_control 50

To increase the brightness by 10%, you might use a command like this:

# backlight_control +10
