Disable touchpad for Dell n4030 laptop in Ubuntu

The external mouse is easy to carry, but the external keyboard is difficult.

So I always think that the notebook touchpad is a chicken rib.

Especially for Ubuntu users, because the driver is not complete, the touchpad cannot be disabled at will.

My laptop is Dell n4030, but this method of prohibiting modules should be effective for most Linux systems.

In ubuntu, the touchpad is recognized as a PS mouse, so you only need to open it as an administrator:

/Etc/modprobe. d/blacklist. conf

Add a row

Blacklist psmouse

Restart your computer to disable the touchpad. Delete this line if you want to enable it later.
