在带有 Kubuntu 17.04 的 Lenovo Ideapad 320 上未检测到触摸板

Question

我刚刚在联想 Ideapad 320 上安装了 Kubuntu 17.04，但未检测到触摸板。笔记本电脑上已经安装了 Windows 10 的触摸板可以正常工作，但 Kubuntu 根本没有检测到，所以它看起来像是驱动程序错误。

这是xinput输出。Logitech 鼠标是我同时使用的 USB 鼠标，效果很好。

$ xinput --list
? Virtual core pointer                          id=2    [master pointer  (3)]
?   ? Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
?   ? Logitech M315/M235                        id=9    [slave  pointer  (2)]
? Virtual core keyboard                         id=3    [master keyboard (2)]
    ? Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ? Power Button                              id=6    [slave  keyboard (3)]
    ? Video Bus                                 id=7    [slave  keyboard (3)]
    ? Power Button                              id=8    [slave  keyboard (3)]
    ? EasyCamera                                id=10   [slave  keyboard (3)]
    ? Ideapad extra buttons                     id=11   [slave  keyboard (3)]
    ? AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

和：

$ cat /proc/bus/input/devices | grep TouchPad

没有输出。我也尝试过这里建议的与 psmouse 相关的东西无济于事

似乎我不是唯一一个，这在其他几个地方都没有答案，在这里和这里，也许在这里

Answer 1

安装这个内核模块。它应该解决这个问题。跑

wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/ppa/+files/elantech-0608-dkms_0.2_all.deb
sudo dpkg -i elantech-0608-dkms_0.2_all.deb

然后重启。

您需要在 BIOS 中禁用安全启动才能让模块加载。

另一种选择是安装这个内核。
