Save Screen Brightness in Ubuntu Linux

  • Open the Linux Terminal (CTRL + ALT + T)
  • Execute the below command to check the  maximum brightness
cat /sys/class/backlight/acpi_video0/max_brightness

If it's 100, you can set the brightness as 30.
  • Add a startup script which will automatically adjust screen brightness when Ubuntu boots up
sudo -i

gedit /etc/rc.local

echo 30 > /sys/class/backlight/acpi_video0/brightness
