每次我设法连接我的魔术键盘时，鼠标就失去了点击任何东西的能力。（但仍然可以移动）。
一旦我进入 sudo modprobe -r btusb并停用蓝牙和键盘，鼠标就重新获得单击窗口/按钮等的能力。
当我使用有线键盘时不会发生这种情况。
我在 Dell XPS8900 台式机上运行。以下是一些可能对蓝牙设备有用的信息。

答案1
再仔细查看后，发现了一个类似的修复方法，也可以解决这个问题。
$ wget "https://dl.dropboxusercontent.com/s/r2pb41rhx65t9zi/BCM20702A1-0a5c-216f.hcd"
$ sudo cp BCM20702A1-0a5c-216f.hcd /lib/firmware/brcm/
$ sudo modprobe -r btusb
$ sudo modprobe btusb
重新启动计算机。
Magic Keyboard 可以连接并且不会破坏窗口/按钮等上的点击/悬停事件。
编辑*** 上述解决方案不起作用，问题仍然存在......
//only momentarily fixes problem
$ sudo modprobe -r btusb
