Ubuntu 上的 Apple MagicTrackpad2

Ait*_*tch 7 ubuntu touchpad apple

我买了一个Apple Magic Trackpad2,想在 Ubuntu 16.04 上使用它。实际上移动指针是有效的,但例如两根手指滚动或点击以单击无效。所以我想出了以下调查:

  1. 点击不会在 上发出任何事件/dev/input/eventX,而移动指针会
  2. 我检查并安装了https://github.com/robbi5/magictrackpad2-dkms,但它也不起作用,因为我发现根本原因是触控板不被识别为触摸板,而是简单的鼠标,因此不使用synaptics驱动程序,但是evdev,请参阅 X11 日志

还有一个新的 X11 conf 注册在/usr/share/X11/xorg.conf.d/49-synaptics-bcm5974.conf. 问题是,在文件中定义了一个部分MatchDriver "synaptics",正如我所说,触控板没有注册为 ,touchpad而是注册为mouse,所以驱动程序是evdev.

所以我正在调查为什么触控板被识别为鼠标。我不确定,但我觉得底层是这样做的,比如udev甚至HAL. 这对我来说真的很新鲜。

我的问题是是否有人可以帮助我解决这个问题,或者至少是哪个组件负责确定input设备是鼠标还是触控板。

非常感谢,意义重大!
