O (distinct _ distinct) O ~ If you want to permanently disable the TouchPad, refer to the method below: install the gsynaptics package. The "TouchPad" option appears in the system menu. Command: sudo apt-get install gsynaptics and then choose system --> Preferences --> TouchPad --> general --> enable TouchPad "to disable annoying touchpad once and for all.

When Ubuntu is started next time, the script will be automatically executed to close the TouchPad.
