![禁用触摸板中间按钮的复选框在哪里?](https://linux22.com/image/130229/%E7%A6%81%E7%94%A8%E8%A7%A6%E6%91%B8%E6%9D%BF%E4%B8%AD%E9%97%B4%E6%8C%89%E9%92%AE%E7%9A%84%E5%A4%8D%E9%80%89%E6%A1%86%E5%9C%A8%E5%93%AA%E9%87%8C%EF%BC%9F.png)
这是 Debian 9。我以前没有过这个功能,也许是因为我一直使用带有单独按钮的触摸板。现在,在无按钮触摸板上有中间按钮功能,它可以不断关闭我的浏览器选项卡,以及它所发挥的其他奇怪的有用技巧。我已经搜索了关闭此功能的选项,但在“所有设置”或通过调整工具都找不到它。网上对此很沉默,或者我不知道如何询问。复选框/开关是否存在?那它在哪里呢?或者CLI方法是什么?

安装就足以xserver-xorg-input-synaptics
停止中间按钮功能。需要重新启动。 (也许还有另一种更温和的方法来应用更改。)安装禁用了 Gnome 中“所有设置”中可用的一些选项,例如边缘滚动。这些是安装后的选项:
$ synclient -l
Parameter settings:
LeftEdge = 1668
RightEdge = 5354
TopEdge = 1516
BottomEdge = 4440

AreaLeftEdge = 0
AreaRightEdge = 0
AreaTopEdge = 0
AreaBottomEdge = 0
HorizHysteresis = 27
VertHysteresis = 27
ClickPad = 1
RightButtonAreaLeft = 3511
RightButtonAreaRight = 0
RightButtonAreaTop = 4066
RightButtonAreaBottom = 0
MiddleButtonAreaLeft = 0

这些设置似乎驻留在/usr/share/X11/xorg.conf.d/70-synaptics.conf
.
配置调整可以写入/etc/X11/xorg.conf
目录或目录中/etc/X11/xorg.conf.d/
。 (显然需要重新启动。也许还有另一种方法......)
