另一种方法：

<span style="font-size:14px;">1.Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, runthe command below will give you the maximum level of your laptopbacklight:
代码:
cat/sys/class/backlight/acpi_video0/max_brightness

Mineis 100, so I can set backlight level from 0 to 100.</span>

<span style="font-size:14px;">2.Run the command below one by one. You’ll get the super userprivilege and open the /etc/rc.local file, a script executed at theend of each multiuser runlevel, with gedit editor.
代码:
sudo gedit /etc/rc.local
</span>

<span style="font-size:14px;">Add the line below before the last. Change the number 0 to the brightnesslevel you want.
