Disable ubuntu mouse and touchpad

Disable ubuntu mouse and touchpad

When I use a notebook, I often encounter a touchpad during typing, which leads to misoperations. The following three methods are summarized in ubuntu.

Shortcut Key

Some laptops support similar Fn + F4. you can directly switch between the two.

Command Method

Run the following command on the terminal to open or close the touchpad.
Sudo modprobe-r psmouse # disable
Sudo modprobe psmouse # How to enable software

Both methods are manual before touchpad-indicator is installed, and this can detect whether there is a mouse to determine whether to close the touchpad.
Sudo add-apt-repository ppa: atareao/atareao
Sudo apt-get update
Sudo apt-get install touchpad-indicator
