通过硬件开关联想Y40禁用无线function
我最近有一台联想Y40笔记本电脑，在我安装ubuntu 14.04（也在现场usb）后无线无法正常工作。 它表示它被硬件开关禁用，但是硬件开关不起作用（它的目的是进入飞行模式但在ubuntu中按下时什么都不做）无线工作在Windows中并且BIOS已启用它。 我尝试重置BIOS，但它仍然无法正常工作。 这是一些命令输出

由于卸载ideapad-laptop显然无线工作，让我们将其列入黑名单：
sudo -i echo "blacklist ideapad-laptop" >> /etc/modprobe.d/blacklist.conf modprobe -r ideapad-laptop exit
你应该全力以赴。
