![系统更新后触摸板不工作](https://linux22.com/image/900199/%E7%B3%BB%E7%BB%9F%E6%9B%B4%E6%96%B0%E5%90%8E%E8%A7%A6%E6%91%B8%E6%9D%BF%E4%B8%8D%E5%B7%A5%E4%BD%9C.png)
因此,在将我的系统从 16.04 更新到 17.10,然后再更新到 18.04 后,我的触摸板不再工作了(升级到 17.04 时已经出现过这种情况,但我认为进一步升级可能会解决这个问题)。“不工作”首先是指光标不动,而且似乎没有“隐形光标”,可以打开菜单等。
以下是一些可能有用的输出:cat /proc/bus/input/devices 给出

在这里找到了我的问题的答案: https://ubuntuforums.org/showthread.php?t=2322413
简而言之:运行 sudo apt-get install xserver-xorg-input-synaptics 并重新启动系统即可解决问题。
不管怎么说,多谢拉。
