屏幕亮度的问题困扰了我很久了，今天搜索无意中发现了这个方法，并且可行，不敢独享，在此贴出来以供有共同问题的网友共享：
1. 备份 /etc/acpi/video_brightnessup.sh 和 /etc/acpi/video_brightnessdown.sh, 以防不测；

代码:

sudo cp /etc/acpi/video_brightnessup.sh /etc/acpi/video_brightnessup.sh.bak
sudo cp /etc/acpi/video_brightnessdown.sh /etc/acpi/video_brightnessdown.sh.bak

2. 编辑 /etc/acpi/video_brightnessup.sh

代码:

sudo gedit /etc/acpi/video_brightnessup.sh

替换为以下内容：

代码:

#!/bin/bash

CURRENT=$(grep "current:" /proc/acpi/video/VGA/LCD/brightness |awk '{print $2}')


case "$CURRENT" in

100)
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness;
;;
87)
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness;
;;
75)
echo -n 87 > /proc/acpi/video/VGA/LCD/brightness;
;;
62)
echo -n 75 > /proc/acpi/video/VGA/LCD/brightness;
;;
50)
echo -n 62 > /proc/acpi/video/VGA/LCD/brightness;
;;
37)
echo -n 50 > /proc/acpi/video/VGA/LCD/brightness;
;;
25)
echo -n 37 > /proc/acpi/video/VGA/LCD/brightness;
;;
12)
echo -n 25 > /proc/acpi/video/VGA/LCD/brightness;
;;
*)
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness ;
;;
esac

3. 编辑 /etc/acpi/video_brightnessdown.sh

代码:

sudo gedit /etc/acpi/video_brightnessdown.sh

替换为以下内容：

代码:

#!/bin/bash

CURRENT=$(grep "current:" /proc/acpi/video/VGA/LCD/brightness |awk '{print $2}')


case "$CURRENT" in

12)
echo -n 12 > /proc/acpi/video/VGA/LCD/brightness;
;;
25)
echo -n 12 > /proc/acpi/video/VGA/LCD/brightness;
;;
37)
echo -n 25 > /proc/acpi/video/VGA/LCD/brightness;
;;
50)
echo -n 37 > /proc/acpi/video/VGA/LCD/brightness;
;;
62)
echo -n 50 > /proc/acpi/video/VGA/LCD/brightness;
;;
75)
echo -n 62 > /proc/acpi/video/VGA/LCD/brightness;
;;
87)
echo -n 75 > /proc/acpi/video/VGA/LCD/brightness;
;;
100)
echo -n 87 > /proc/acpi/video/VGA/LCD/brightness;
;;
*)
echo -n 50 > /proc/acpi/video/VGA/LCD/brightness ;
;;
esac

大功告成，试试Fn + UP/Down吧。[/code][/u]
