一般笔记本都有个无线开关,可以打开和关闭无线网卡,开的时候灯是蓝色,关的时候是琥珀色 今天在办公室上网,随手把无线开关拨了一下,灯的颜色从蓝色变成琥珀色,因为用的是有线上网,当时还没有觉得什么不对劲 晚上回家后,发现杯具了,进arch后,灯不变蓝了,不管你怎么拨开关都没有反应 在xp下一般先关再开灯就变蓝了,在linux下貌似不行 baidu+google,发现很多类似的问题,不过都没有说怎么解决,直到我在国外的网站上找到这个帖子: ================================================== You can manually check by typing modprobe acer_wmi then. echo 1 > /sys/devices/platform/acer-wmi/wireless At this point the wifi light should come on. I use Gnome network manager so if you have the wifi configured the network connection should start within 2 min. Now to make this work at boot time edit the file /etc/rc.local and add the following to the end. modprobe acer_wmi echo 1 > /sys/devices/platform/acer-wmi/wireless Of course this all assumes you can see and configure the device. Have fun Ray ================================================================== 马上$lsmod | grep wmi 果然发现一个hp_wmi的模块 按照帖子中提到的 我找到如下文件/sys/devices/platform/hp-wmi/rfkill/rfkill0/state cat后发现为0 马上$sudo echo 1 > /sys/devices/platform/hp-wmi/rfkill/rfkill0/state 立刻灯就变蓝了 看来这个开关在linux下不止硬开关这么简单哦 |
