I'm so tired of the touchpad that I need to beat...

When using a notebook, you often accidentally touch the touch screen, which causes the cursor to run around.

Method 1:

Very simple, just type sudo modprobe -r psmouse
If you want to open it, just remove - r.

Of course, you can also write a file with the bash you learned recently, and then switch the touch screen on and off interactively every time.

You can do not write with vim ~/psmouse, just write the following code in psmouse (you can copy and paste directly, of course), save and exit, and then run directly. / psmouse.

Code:

echo ""  
echo ""  
read -p "Turn the touchpad on or off?(open/Close)(y/n): " yn  
if [ "$yn" = "y" ] || [ "$yn" = "Y" ]  
then  
    sudo modprobe psmouse  
    echo "Touch pad is on"  
    echo ""  
    echo ""  
elif [ "$yn" = "n" ] || [ "$yn" = "N" ]  
then  
    sudo modprobe -r psmouse  
    echo "Touch pad is off"  
    echo ""  
    echo ""  
fi  

Method two:

Dazzled, right? You pull out your mouse and try:

jack@jack-W65KJ1-KK1:~ $ xinput list

A few are missing...
As we all know, touchpad is the line:

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

You can type xinput -h for usage
Use xinput disable 17 to disable the touchpad
Use xinput enable 17 to turn on the touchpad
That is: XInput disable / enable < device > (here is the ID of the device)
