Disabling touch screen on Ubuntu

I am trying to disable the touch screen on my Dell inspiron 15 7000. When I run the xinput --list, I get this list.

⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ 2.4G Mouse id=10 [slave pointer (2)] ⎜ ↳ DELL07EC:00 06CB:7E92 Touchpad id=13 [slave pointer (2)] ⎜ ↳ ELAN2097:00 04F3:2504 id=14 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=20 [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)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ Integrated_Webcam_HD: Integrate id=11 [slave keyboard (3)] ↳ Integrated_Webcam_HD: Integrate id=12 [slave keyboard (3)] ↳ ELAN2097:00 04F3:2504 Pen id=15 [slave keyboard (3)] ↳ Intel Virtual Button driver id=16 [slave keyboard (3)] ↳ Intel HID events id=17 [slave keyboard (3)] ↳ Dell WMI hotkeys id=18 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard 

Please which one of them (ids) is for the touch screen?

vanadium is right, it is id 13. To disable type:

xinput disable 13 

To enable:

xinput enable 13 

To disable permanently, you'll need to add this on boot:

crontab -e 

add line:

@reboot xinput disable $(xinput --list | grep DELL07EC | head -n 1 | awk -F ' ' '{print $2}' | awk '{print $1}' | sed s/id=//)
