Ubuntu 16.04。 Synaptics触摸板function停止工作
Distributor ID: Ubuntu Description: Ubuntu 16.04.1 LTS Release: 16.04 Codename: xenial 触摸板function（双指滚动等）突然停止工作，可能在上次更新后。 系统 – >首选项 – >鼠标中缺少触摸板选项卡。 我的触控板就像一个鼠标。
synclient输出：
Couldn't find synaptics properties. No synaptics driver loaded?
xinput list输出：
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ PS/2 Synaptics TouchPad id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ...

已经尝试重新安装xserver-xorg和xserver-xorg-input-synaptics
有任何想法吗？
升级到16.04后我遇到了同样的问题。 我做的第一件事是在/ etc / X11中查找synaptics配置文件，但我不再看到它了。 所以我这样做了：
sudo mkdir /etc/X11/xorg.conf.d cd /etc/X11/xorg.conf.d sudo cp /usr/share/X11/xorg.conf.d/50-synaptics.conf .
这对任何人都没有帮助。 所以这一步可能是完全不必要的。
之后我注意到我的触摸板被禁用了。 要修复，我这样做了：
synclient TouchPadOff=0
重新启动后，这似乎不再是一个问题。
