触控板鼠标点击无响应

尝试了一段时间后，终于成功使用 Seagate 外置硬盘在我的 Acer D255 e 上运行了 Ubuntu。除了鼠标之外，其他都运行正常。虽然触控板允许我选择程序并打开应用程序。我无法在应用程序内单击选择，我唯一可以单击选择的方式是在应用程序内使用 Tab/箭头键/Enter 组合。

在通用访问下，指针和单击：鼠标键关闭，模拟辅助单击打开，悬停单击关闭

在鼠标和触摸板的所有设置下常规：主按钮左键/双击一半触摸板：打开缓慢移动 1/3 仅选择点击

我的系统。

运行 Ubuntu 14.04 LTS 内存 2GB Intel Atom CPU N555 @1,50GHz x 4 32 位

有没有关于如何完全启用触控板和鼠标点击的提示？这样我就可以充分享受使用 Ubuntu 精美功能的奇妙体验。谢谢

答案1

经过一些研究，删除并重新加载触控板/鼠标驱动程序似乎可以暂时解决问题。

打开终端 (Ctrl-Alt-T) 并运行

代码： sudo modprobe -rv psmouse sudo modprobe -v psmouse

要设置 Synaptics 触摸板的各种选项，请查看
man synclient
和
man xinput

例如，Asus eeepc 上有以下选项：
