三指点击无法与 Synaptics 触摸板驱动程序配合使用

三指点击无法与 Synaptics 触摸板驱动程序配合使用

我有 Ubuntu 14.04 Unity,我听说默认情况下应该启用系统手势。两指滚动效果很好,但三指手势不行。这是 xinput:

内核版本

3.19.0-49-generic

我是否遗漏了一些简单的东西,或者这里确实出了什么问题?

答案1

应该可以在任何带有“synclient”的设备上运行。只需运行:

“synclient TapButton3=2”

这将中指按钮设置为配置的手势动作,即粘贴选定的测试。

答案2

我正在使用 xubuntu 16.04

从您的 synclient

TapButton1 = 1 ;;;; 左按钮 一根手指 TapButton2 = 3 ;;;; 右按钮 两根手指 TapButton3 = 0 ;;;; 未分配按钮 三根手指

我使用 1 个手指左键 (1) 2 个手指中键 (2) 3 个手指右键 (3)

但现在我的触摸板有时会混淆两根手指和三根手指。

希望能帮助到你。
