如何在打字时启用触摸板点击功能？配置每隔几秒就会重置一次

我想（暂时）禁用在键盘上打字时禁用触摸板点击的功能，以便能够玩需要同时通过鼠标和键盘进行交互的游戏，而无需使用物理外接鼠标。

换句话说，如何才能同时按下键盘上的按键并点击内容？

到目前为止，我在 Ask Ubuntu 上找到的所有内容都是相反的，如何在打字时禁用触摸板。

一些系统信息，我正在运行 Ubuntu 16.04，并将xinput我的触摸板列为

SYN1B7F:00 06CB:7406 Touchpad

更新：阅读后我尝试了这篇关于 ElementaryOS 的文章。

首先，和列出的xinput属性synclient：

因此，从我所读的内容来看，TouchpadOff在synclient和Synaptics Off (311)中xinput应该有有趣的设置：0 =“始终启用”，1 =“始终禁用”，2 =“键入时禁用”

我尝试过改变它（仅通过xinput或仅通过synclient以及同时通过两者，多次）：

$ xinput set-prop 11 311 0
$ synclient TouchpadOff=0

但是，这些设置并不是持久的。检查值立即地设置后，显示更改为 0，正如预期的那样：

$ xinput list-props 11 | grep Off
    Synaptics Off (311):    0
$ synclient | grep TouchpadOff
    TouchpadOff             = 0

但仅仅几秒钟之后，值就会自动重置回 2：

$ xinput list-props 11 | grep Off
    Synaptics Off (311):    2
$ synclient | grep TouchpadOff
    TouchpadOff             = 2

但请注意，其他设置（例如synclient TapButton3=2，我使用它来启用三指点击作为中键单击）可以正常工作并且不会重置。

我不知道这里发生了什么以及为什么。请帮助我正确且持续地设置此配置，以便即使在打字时也能启用触摸板。

答案1

我可以设置触摸板在当前会话中始终启用，即使在打字时也是如此，只需终止syndaemon进程. 这也会自动TouchpadOff=0生效。synclient

killall syndaemon

但这不会阻止syndaemon下次重启（或登录？）时自动启动。

要在再次打字时禁用触摸板，您可以重新启动或syndaemon通过运行重新启动

syndaemon -i 1.0 -t -K -R -d

再次，这会自动处理其自身的TouchpadOff=2设置synclient。
