如何在联想ThinkPad e531上使用Trackpoint但禁用触摸板

我有一台Lenovo ThinkPad e531笔记本电脑。该模型同时具有触摸板和跟踪点。我想使用Trackpoint，因为我以前的笔记本电脑已经习惯了Trackpoint，但是我也想禁用触摸板，以防止意外触摸它。

问题是，e531上没有专用的跟踪点按钮。

这是e530型号的图片：

您可以看到它在触摸板上方有一个单独的按钮，可以在使用轨迹点时使用它们。

这是我的模型（e531）的图片：

如您所见，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”中），并使用跟踪点在周围移动鼠标指针，但是无法单击。您可能会想到，这不是很有用。

我在想的是应该有一种方法可以禁用触摸板的鼠标运动功能，但仍保持可单击状态，以便将其用作轨迹桥的鼠标按钮。我的问题是，怎么做。

我认为可以使用该xinput实用程序来实现它，但是由于我不太熟悉它，我不知道该怎么做。有人可以在这里为我提供帮助，或者至少为我指明正确的方向吗？

这是xinput我机器上的输出：

@thom评论的摘要，我这样做是为了使其工作：

1. 打开文件/usr/share/X11/xorg.conf.d/50-synaptics.conf进行编辑。
2. 查找Section "InputClass"以下行Identifier "Default clickpad buttons"。
3. SoftButtonAreas值的编辑选项64% 0 1 42% 36% 64% 1 42%，这是右键和中间按钮的大小。

4. 启用选项AreaBottomEdge并将值更改为1，这将禁用触摸板移动。

   如果一切正常，您的课程应如下所示：

   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。

我使用S440 btw，但是我认为这对于使用无按钮触摸板的所有型号都适用。
