笔记本会随着打开的页面自动调节亮度，怎么关闭呢？

sudo su
echo 9 > /sys/class/backlight/*/brightness

试试看一下，

原贴下面的字是5，我试验了下用9亮度合适点。先用着看。

亮度调节后无法保存。

sudo gedit /etc/rc.local

插入

echo 0 > /sys/class/backlight/acpi_video0/brightness

其中echo 后面的值为0-10，对应为0到100%
最终效果：

#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will “exit 0″ on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing.
echo 0 > /sys/class/backlight/acpi_video0/brightness

exit 0
