我刚刚完成了将ubuntu 16.04更新到16.10的工作，并且遇到了几个问题，其中最令人讨厌的是新的触控板配置。
Xorg启动时，触控板将使用绝对触摸坐标，例如图形输入板。
Xorg.log表示以下内容：
72.992] (II) config/udev: Adding input device ETPS/2 Elantech Touchpad (/dev/input/event7)

72.994] (II) No input driver specified, ignoring this device.
72.994] (II) This device may have been added with another device file.
系统设置GUI具有用于触控板和鼠标的单个配置选项卡，因此我不知道如何正确地对其进行重新配置。我应该更改xorg.conf文件吗？如何？
在终端中运行
sudo apt install xserver-xorg-input-all
然后重启。
出于某种原因，升级时删除了用户空间驱动程序。
