I know this question has expired, but since I searched around and found
the solution I thought I'd share it for those who are still searching. I
know it's not the best way, but it works.

To enable the Touchpad you'll need to do the following from terminal:

1. sudo nano /etc/rc.local
2. Add the following line before the exit command. (sudo bash -c 'echo 1 > /sys/devices/platform/i8042/serio4/reg_07')
3. press CTRL+O then press Enter.

this will enable the touch-pad on start-up but it might stop working
when suspended and/or hibernated. a workaround for this is:

1. sudo nano /etc/pm/sleep.d/sr-enable

and copy the following to the file

#!/bin/bash

case "$1" in
    suspend)
        ;;
    resume)
       sudo bash -c 'echo 1 > /sys/devices/platform/i8042/serio4/reg_07'
        ;;
    *)
        ;;
esac

3. press CTRL+O then press Enter.

4. sudo nano /etc/pm/sleep.d/ht-enable

5. again copy this

#!/bin/bash

case "$1" in
    hibernate)
        # executed on suspend
        ;;
    thaw)
        sudo bash -c 'echo 1 > /sys/devices/platform/i8042/serio4/reg_07' # executed on resume
        ;;
    *)
        ;;
esac

6. press CTRL+O then press Enter.

7. then (sudo chmod +x /etc/pm/sleep.d/ht-enable && sudo chmod +x
/etc/pm/sleep.d/sr-enable)

8. then issue the following command ( sudo update-initramfs -u -k all )

Title:
  Touchpad on ASUS X750LN notebook doesn't work on Ubuntu

Status in linux package in Ubuntu:
  Triaged

Bug description:
  The touchpad on my ASUS X750LN notebook (modell R751LN-T4102H) doesn't work on Ubuntu 14.04.1 LTS.
  It seems to me, that the touchpad is not recognized by linux. It works completely under Windows 8.1. An USB mouse works fine under linux.

  The keyboard Fn key also doesn't work on linux.

  On Windows I found this information, which may be helpful. It is not
  the original text since I translated it from german.
