关闭笔记本上盖的触点

代码： 全选

/var/log/dmesg

代码： 全选

[    0.568735] input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input2
[    0.568802] ACPI: Lid Switch [C20C]

用acpi_listen测试那个触点的输出

代码： 全选

acpi_listen
button/lid C20C 00000080 00000012
video C085 00000080 00000000

button 错了，命名应该是 Lid Off ，然而偏偏搞成了 Lid Switch
现在关lcd只有

代码： 全选

xset dpms force off 

或者等待自动关闭

麻烦各位用笔记本的路过同学也把自己的这两项信息帖出来借我看看

嘿嘿~俺的HP compaq本本没有触点

额？那能正常关闭lcd么，我的闪一下就over了

呀呀个蛋的，怎么都是 Switch的？ 应该是Off的呀

[dwl301]

嘿嘿，从来不把本子合上……

额？那能正常关闭lcd么，我的闪一下就over了

刚才都想请问什么一下：什么是lcd ？ 什么是本本上盖的触点？什么是闪一下就over ? 给俺截个图瞧瞧吧？学习一下？
我的本本挺正常的关机，触摸屏都很正常啊

我说的lcd指的是笔记本的液晶屏
那个触点是用来识别笔记本上盖是否关闭的，所有的机器都有，不过有的隐藏起来了
闪一下是lcd关闭一下（一瞬间）然后又正常亮起来了
这个发不了啊

代码： 全选

input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input3
ACPI: Lid Switch [LID0]

代码： 全选

 acpi_listen
button/lid LID0 00000080 00000001
button/lid LID0 00000080 00000002
button/lid LID0 00000080 00000003
button/lid LID0 00000080 00000004
button/lid LID0 00000080 00000005
button/lid LID0 00000080 00000006

合上灭了，打开就亮了。
看不到触点。

折衷解决办法

代码： 全选

vim /etc/acpi/events/lidbtn
# /etc/acpi/events/lidbtn
# Called when the user closes or opens the lid

event=button[ /]lid
action=/etc/acpi/lid1.sh

把原来的控制脚本 /etc/acpi/lid.sh 换成自己的/etc/acpi/lid1.sh

代码： 全选

vim /etc/acpi/lid1.sh
#! /bin/bash
xset dpms force off

这样虽然能正常关闭，可是每次开盖的时候仍然会再关闭一次，不过鼠标键盘都可以唤醒，没办法啦，谁让咱这么菜呢，先这样，以后再说
