如何在联想 ThinkPad e531 上使用指点杆但保持触摸板禁用

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?

答案1

来自@thom 评论的总结,我已完成此操作以使其发挥作用:

  1. 打开文件/usr/share/X11/xorg.conf.d/50-synaptics.conf进行编辑。
  2. 查找Section "InputClass"以下哪一行Identifier "Default clickpad buttons"
  3. 编辑选项的SoftButtonAreas64% 0 1 42% 36% 64% 1 42%,这是右侧和中间按钮的大小。
  4. 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
    
  5. 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。
