求教在笔记本上的Ubuntu系统中保存屏幕亮度的详细方法

RT，我在网上搜过，找到了如下答案，但是不起作用：
1.修改/etc/default/acpi-support
ENABLE_LAPTOP_MODE=true
2.修改 /etc/laptop-mode/laptop-mode.conf
交流电模式下使用 laptop mode
#
# Enable laptop mode when on AC power.
#
ENABLE_LAPTOP_MODE_ON_AC=1
＃电池那也可设为1
使用 laptop mode 进行LCD亮度控制
#
# Should laptop mode tools control LCD brightness?
#
CONTROL_BRIGHTNESS=1
#
# Commands to execute to set the brightness on your LCD
#
BATT_BRIGHTNESS_COMMAND=”echo 0″
LM_AC_BRIGHTNESS_COMMAND=”echo 9″
NOLM_AC_BRIGHTNESS_COMMAND=”echo 9″
BRIGHTNESS_OUTPUT=”/sys/class/backlight/acpi_video1/brightness”
前面的步骤都改了，但是在“ 2.修改 /etc/laptop-mode/laptop-mode.conf”中找不到“CONTROL_BRIGHTNESS”这一项
我自己在/etc/laptop-mode/laptop-mode.conf加了一个“CONTROL_BRIGHTNESS=1”，但是没有效果
