This question is an exact duplicate of:

I have a broken touchscreen that goes crazy when enabled.

Should I add Option "Ignore" "on" to the /usr/share/X11/xorg.conf.d/10-evdev.conf file?

    Section "InputClass"
    Identifier "evdev touchscreen catchall"
    MatchIsTouchscreen "on"
    MatchDevicePath "/dev/input/event*"
    Driver "evdev" 
    **Option "Ignore" "on"**
    EndSection

Why cant I just change MatchIsTouchscreen to "off" ???????????????

I have read on a lot of threads that suggest add Option "Ignore" "on". One thread said editing the configuration file can "...blow up xserver!" Is there any truth to that?

If editing this file /usr/share/X11/xorg.conf.d/10-evdev.conf is ok, what is the best method?

   1) sudo nano /usr/share/X11/xorg.conf.d/10-evdev.conf 
   2) sudo gedit /usr/share/X11/xorg.conf.d/10-evdev.conf
   3) from files simply follow path to -evdev.conf file and edit and save

I currently run xinput disable "ELAN Touchscreen" in my startup applications, but when my laptop wakes from suspend the touchscreen is enabled. So I either reboot, or struggle to run the command in the terminal; which is a real challenge sometimes when the screen is going crazy.

I know this question has been asked a number of times but I imagine others must be as confused as I am.

Edited file the file with

sudo nano /usr/share/X11/xorg.conf.d/10-evdev.conf

Changed MatchIsTouchscreen from "on" to "off"

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "off"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        EndSection

"ELAN touchscreen" is disabled and no longer detected in xinput list.
