Software Brightness Adjustment on Linux​

Use a DDC/CI program to adjust the monitor brightness. This example uses the ddcutil tool.

Install ddcutil​

sudo apt-get install ddcutil -y

Detect DDC/CI‑capable monitors​

sudo ddcutil detect

Adjust monitor brightness​

Replace <value> with a number between 0 and 100.

sudo ddcutil setvcp 10 <value>

Example: Set brightness to 50%

sudo ddcutil setvcp 10 50
