One method to disable the touchpad, would be to write a simple script and run that script at startup. To do this, you will need to know the name of your touchpad. Open a terminal and run the command
xinput -list
The output on my computer is
chick@dad:~$ xinput -list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)]
⎜ ↳ Logitech M315/M235 id=9 [slave pointer (2)]
⎜ ↳ ELAN Touchscreen id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Laptop_Integrated_Webcam_HD id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
↳ Dell WMI hotkeys
and the name of my touchpad is SynPS/2 Synaptics TouchPad
The touchpad can be diabled by xinput --disable 'SynPS/2 Synaptics TouchPad', and re-enabled by xinput --enable 'SynPS/2 Synaptics TouchPad'
A simple script to run this command, for example
#!/bin/bash
xinput --disable 'SynPS/2 Synaptics TouchPad'
can now be written, and executed at startup or login . Good instructions on how to do that can be found at How to run scripts on start up?
