问题描述
我有一台联想 ThinkPad e531 笔记本电脑。该型号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它，但我也想禁用触摸板，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，您可以在使用跟踪点时使用这些按钮。
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)并使用跟踪点来移动鼠标指针，但是无法单击。正如您可能想象的那样，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，但仍然保持可点击，这样我就可以将它用作 trackpont 的鼠标按钮。我的问题是，怎么做。
我假设它可以使用 xinput 实用程序来实现，但由于我对它不是很熟悉，我不知道如何。任何人都可以在这里帮助我，或者至少指出我正确的方向？
这是我机器上 xinput 的输出：

最佳答案
@thom 评论的总结，我这样做是为了让它发挥作用：
-
打开文件
/usr/share/X11/xorg.conf.d/50-synaptics.conf进行编辑。 -
找到
Section "InputClass"，下面的行是Identifier "Default clickpad buttons"。 -
将
SoftButtonAreas的选项编辑为值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。如果一切正常，您的课程应该如下所示：
Section "InputClass" Identifier "Default clickpad buttons" MatchDriver "synaptics" Option "SoftButtonAreas" "64% 0 1 42% 36% 64% 1 42%" Option "AreaBottomEdge" "1" EndSection -
保存文件和 re-login。
我使用 S440 顺便说一句，但我认为这应该适用于所有使用无按钮触摸板的型号。
