如何在联想 ThinkPad e531 上使用指点杆但保持触摸板禁用

2024-6-9 • tag-icon

我有一台联想 ThinkPad e531 笔记本电脑。此型号既有触摸板又有指点杆。我想使用指点杆，因为我在之前的笔记本电脑上已经习惯了它，但我还想禁用触摸板，以防止意外触摸它。

问题是，e531 上没有专用的指点杆按钮。

这是 e530 型号的图片：

您可以看到触摸板上方有一个单独的按钮，您可以在使用指点杆时使用它。

这是我的型号（e531）的图片：

如你所见，这里没有按钮。只有触摸板。

我可以禁用触摸板（在系统设置>鼠标和触摸板) 并使用轨迹点移动鼠标指针，但这样就无法单击。正如您可能想象的那样，这不是很有用。

我在想，应该有一种方法可以禁用触摸板的鼠标移动功能，但仍保持其可点击，这样我就可以将其用作轨迹球的鼠标按钮。我的问题是，如何做到这一点。

我认为可以使用xinput实用程序来实现，但由于我对它不太熟悉，所以我不知道该怎么做。有人能帮我吗，或者至少给我指明正确的方向？

xinput这是我的机器上的输出：

来自@thom 评论的总结，我已完成此操作以使其发挥作用：

打开文件/usr/share/X11/xorg.conf.d/50-synaptics.conf进行编辑。
查找Section "InputClass"以下哪一行Identifier "Default clickpad buttons"。
编辑选项的SoftButtonAreas值64% 0 1 42% 36% 64% 1 42%，这是右侧和中间按钮的大小。

启用选项AreaBottomEdge并将值更改为1，这将禁用触摸板移动。

如果一切顺利的话，你的课程看起来应该是这样的：

Section "InputClass"
    Identifier "Default clickpad buttons"
    MatchDriver "synaptics"
    Option "SoftButtonAreas" "64% 0 1 42% 36% 64% 1 42%"
    Option "AreaBottomEdge" "1"
EndSection

保存文件并重新登录。

顺便说一下，我使用 S440，但我认为这应该适用于所有使用无按钮触摸板的型号。
