Re,

I make the same test with no boot option (without "acpi=off") and the
result is very different (we can find touchpad, MSI buttons,...).

I have a loop trace in my syslog :

Title:
  [MSI GP72 6QE Leopard Pro] Touchpad not detected on 16.04

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,
  I just install Ubuntu 16.04 on my new MSI laptop G72 6QE.
  My touchpad doesn't work and recognize at all.

  I try :
  - Fn+F3 to activate my touchpad
  - xinput list and is not listed
  - xev and nothing append (no signal)
  - cat /proc/bus/input/devices ddoesn't display touchpad (only HDMI, mic, headphone, external mouse and keyboard)
  - I don't know if there is a link, but some buttons of my keyboard don't work (like Fn+arrows to manage sound and luminosity) :
