16.10 升级后按“打字”键时触摸板不工作

Question

我最近从 16.04 升级到 16.10，现在触摸板在按下键盘键时停止响应。这些键不包括alt、super、ctrl、shift、Fn等功能键。

在跑步时xinput list，我得到

我曾SynPS/2 Synaptics TouchPad在绝望的尝试中尝试禁用，但无济于事。的输出gsettings list-recursively | grep touch：

我用谷歌搜索了几个小时。似乎有一个在早期版本中输入时禁用触摸板的设置，但我过去从未启用过这些设置。当我升级到 16.10 时，这个问题就开始了。问题是它妨碍了我在 Linux 上做的小游戏。请帮忙。

我看到问题是libinput Disable While Typing Enabled (297)财产。所以，我只是用 set-prop 设置它？

Answer 1

虽然 @Pilot6 的答案对于 Xorg 来说效果很好，但它对运行 Wayland 的系统没有任何作用。

如果其他人在 Ubuntu 17.10+ 上或在任何版本上运行 Wayland 时遇到此问题，这里有一种解决方法。

具体来说，运行：

gsettings set org.gnome.desktop.peripherals.touchpad disable-while-typing false

将指示 Gnome 告诉 libinput 禁用disable-while-typing.

我从/u/Eingaica在 reddit 上的帖子中找到了这个。

如果使用 Ubuntu 16.04 或更早版本，或者使用 Xorg，我建议遵循Pilot6对这个问题的回答。

Answer 2

升级libinput安装后。您可以通过这种方式禁用此功能。在终端中运行

sudo -H gedit /usr/share/X11/xorg.conf.d/60-libinput.conf

并在之后添加到触摸板部分 Driver "libinput"

 Option "DisableWhileTyping" "false"

保存文件并重新启动会话或重新启动。

解决此问题的另一种方法是卸载xserver-xorg-input-libinput. 这将使用xorg-synaptics.
