关闭触摸板、指点杆

我刚刚在 HP 8460W 上​​安装了 18.04.2。通常在笔记本电脑上我喜欢：

  1. 连接 USB 鼠标时关闭触摸板
  2. 关闭键盘中间的小操纵杆（及其空格键附近的按钮）永远

在 Ubuntu 中我该如何做这两件事？如果有必要的话，我选择了默认的基于 Gnome 的桌面。

  1. 要在连接 USB 鼠标时关闭触摸板，请运行以下命令

    gsettings set org.gnome.desktop.peripherals.touchpad send-events 'disabled-on-external-mouse'

要重置上述命令，请运行以下命令

gsettings reset org.gnome.desktop.peripherals.touchpad send-events
  1. 要关闭小操纵杆，您需要从输出中找出此操纵杆的 ID xinput，也许需要禁用有意义的 ID，然后查看哪一个是正确的 ID。

从您的xinput输出来看，操纵杆的 ID 似乎是 11。

要禁用此操纵杆，请运行以下命令

xinput --disable 11

上述命令将禁用操纵杆，直到您注销或重新启动。

要永久禁用它，请xinput --disable 11在启动应用程序首选项列表中添加命令。
