我最近从 16.04 升级到了 16.10，现在按下键盘键时触摸板会停止响应。这些键不包括功能键，例如 alt、super、ctrl、shift、Fn 键等。
在跑步时xinput list，我得到
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DLLC6B2:00 06CB:75BF Touchpad id=11 [slave pointer (2)]

我曾拼命尝试SynPS/2 Synaptics TouchPad禁用它，但无济于事。输出gsettings list-recursively | grep touch：

我在 Google 上搜索了几个小时。在早期版本中似乎有一个设置可以禁用打字时的触摸板，但我以前从未启用过这些设置。这个问题在我升级到 16.10 后就开始了。问题是它妨碍了我在 Linux 上玩的一些小游戏。请帮忙。

我发现问题出在libinput Disable While Typing Enabled (297)属性上。那么，我只需使用 set-prop 进行设置即可？
答案1
而@Pilot6 的回答对 Xorg 来说运行良好，它不会对运行 Wayland 的系统产生任何影响。
如果其他人在 Ubuntu 17.10+ 上遇到此问题，或者在任何版本上运行 Wayland 时遇到此问题，这里有一种方法可以解决它。
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。
我发现这个/u/艾因加卡的在 reddit 上发帖。
如果使用 Ubuntu 16.04 或更早版本，或者使用 Xorg，我建议遵循Pilot6 的回答对这个问题
答案2
升级libinput安装完成后。您可以通过以下方式禁用此功能。在终端中运行
sudo -H gedit /usr/share/X11/xorg.conf.d/60-libinput.conf
并将其添加到触摸板部分之后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。这将恢复 16.04 中的所有内容xorg-synaptics。
