小弟初学匝道， 请多多指教：
ThinksPad T23硬盘安装Kubnutn 7.04 在使用的时候发现 开机后默认LCD屏幕亮度过高，用Fn+End把亮度降低后，在系统重启后调整后的亮度无法保存，还是表现出很亮的情况。
想请教Fn+End调节的到底是系统里面的那个配置文件参数呢，我应该怎么做才能把这个问题解决掉，谢谢

在system-->preferences-->power management下面手动修改亮度就可以保存至下次启动

顶！

顶了

用kpowersave试试

学习中。。。。。。。。。。。

电源管理里怎么没有亮度调节啊，我用的是8.04

哦的也没有。。。

我怎么没有power management这个选项呢？是不是更新不完全？

这是我以前用的方法，保存着，今天有用处了吧




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 0" “““我都设成最低值了”””
NOLM_AC_BRIGHTNESS_COMMAND="echo 0"
BRIGHTNESS_OUTPUT="＊＊＊＊＊＊＊＊＊＊＊＊＊＊/brightness"#注意这里＊＊＊＊＊＊＊＊＊根据下面的来添（我选了第二种）

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
# * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
# be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
# the command "echo <value>". The possible values can be listed using the
# command:
#
# cat /proc/acpi/video/VID/LCD/brightness

# * If you have a file /sys/class/backlight/.../brightness, then you can use
# that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
#
# As far as I understand it the values are between 0 and
# the value contained in the file /sys/class/backlight/.../max_brightness.

楼上的那么复杂？难道为了调个亮度还要去编个shell。。。

我的也是。3月份返厂回来就是这样的了。一开始也挺郁闷的。不过可以下个关闭键盘灯的软件，把键盘灯关了，那样就不会这么费电了。软件挺好找的。
