东芝 L55D-C5269 笔记本电脑上已识别并启用的触摸板完全不起作用。搜索后发现 Elan 触摸板有很多不同的解决方案，但似乎都不起作用。
我尝试过的一些方法：
-以各种方式调整 xorg conf 文件
-安装了 Libinput 并卸载了 Synaptics
-重置 BIOS
其他一些人通过更新内核解决了他们的问题，但我的内核无论如何都是最新的……
我对 Linux 还很陌生，所以我希望我只是错过了一个简单、小的细节，并且有一个简单的解决方法。

答案1
一些 Acer 笔记本电脑（例如 Spin 5）具有触摸板锁定功能，可通过按 FN+F7（或仅按 F7，取决于 BIOS 配置）来访问。
只要禁用锁定，Acer Spin 5 上的 ELAN 触摸板和触摸屏都可以在 Fedora 28 的 Xorg 下工作，无需 xorg.conf 文件。即使禁用锁定，触摸屏也可以工作。
答案2
这不是 ubuntu 的问题。
我用这种方法解决了：
- 重新启动笔记本电脑，（F2）进入 BIOS。
- 按下 FN+F5。触摸板开始工作（再次按下 FN+F5，它将再次被禁用）。
- 启动 Ubuntu 后它就可以像以前一样运行了。
