ubuntu下关闭笔记本电脑的触摸板

烦死我了,欠揍的触摸板......

---

用笔记本时经常不小心碰到触摸屏从而导致光标乱跑

方法一：

很简单，输入sudo modprobe -r psmouse即可
如果想打开的话, 将-r去掉即可。

当然也可以用最近学的bash写个文件，然后每次交互式的开关触摸屏。

你可以用vim ~/psmouse进行别写，只需要在psmouse中写入如下代码（当然可以直接复制粘贴）然后保存退出，以后直接./psmouse来运行。

代码：

echo ""  
echo ""  
read -p "开启或关闭触摸板?(开启/关闭)(y/n)：" yn  
if [ "$yn" = "y" ] || [ "$yn" = "Y" ]  
then  
    sudo modprobe psmouse  
    echo "触摸板已经开启"  
    echo ""  
    echo ""  
elif [ "$yn" = "n" ] || [ "$yn" = "N" ]  
then  
    sudo modprobe -r psmouse  
    echo "触摸板已经关闭"  
    echo ""  
    echo ""  
fi  

方法二：

眼花缭乱对吧，你把自己的鼠标拔了试试：

    ↳ Power Button                                id=6    [slave  keyboard (3)]

少了几个......
其实咱们都知道，触摸板是这一行：

⎜   ↳ SynPS/2 Synaptics TouchPad                  id=17    [slave  pointer  (2)]

可以输入xinput -h看一下用法
使用xinput disable 17来禁用触摸板
使用xinput enable 17来开启触摸板
即：xinput disable/enable <device>(此处是该设备的id)
