Sometimes, touch-pad is not disable when you typing on your laptop, and you might be got crazy with your laptop, and want to fuck it up. Calm down! You can overcome this irritation by following the instruction below:

Use xinput command to list your device and check PS/2 device information

xinput list




Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Logitech USB Receiver                   	id=9	[slave  pointer  (2)]
⎜   ↳ Logitech USB Receiver                   	id=10	[slave  pointer  (2)]
⎜   ↳ PS/2 Generic Mouse                      	id=13	[slave  pointer  (2)]

Then, id=13 is my touch pad id on my laptop, so I will use the command below to disable or enable it

xinput set-prop 13 "Device Enabled" 0 # disable
xinput set-prop 13 "Device Enabled" 1 # enable

13 is id of touch pad device in my T420 laptop, maybe yours different . You can you xinput list to get the id of touch pd device on your laptop.

If you want make it more convenience, you can make a script to make it easier

for eg: ~/touchpad.sh

#/bin/bash
xinput set-prop 13 "Device Enabled" $1

then create an alias

alias touchpad='sh ~/touchpad.sh'

use it:

touchpad 0 # 1 to enable it again

Help this could help you ! ;) And you will love your laptop with fedora (or linux in general) OS again ;)
