关于安装laptop-mode-tools后电池模式下鼠标等外设失去响应的解决办法
发表于 : 2012-10-27 10:22
新装12.04,基本感觉良好,折腾好双显卡切换等等后又习惯性的安装了laptop-mode-tools,没想到拔掉电源线后鼠标立马不动了,明显不可能是鼠标故障,所以觉得问题应该出在laptop-mode-tools上面,仔细检查后附解决方案如下
打开如下这个配置文件
可以看到laptop-mode-tools通过该配置文件的设定来自动关停USB外设,问题就在这里了,我们需要把自己的鼠标添加到白名单也就是软件说明里的BLACKLIST里面
下面的问题就是如何找到自己鼠标的设备ID,可以用如下的命令
我的本本输出如下

注意看红色加粗部分文字,mouse代表你的鼠标,然后把ID如我的0461:4de2复制

把刚刚复制的ID信息粘贴到这里
AUTOSUSPEND_USBID_BLACKLIST="0461:4de2"
保存退出,拔掉电源线测试下,是不是鼠标依然正常?
enjoy!
PS:其他的USB外设诸如手写板,U盘,移动硬盘等都可以如法炮制,想不停哪个就不停哪个
