I installed Unity 12.04 on an Acer 725, everything worked but the touchpad.

This got it working.

open terminal:

cd /etc/modprobe.d
gksudo gedit options.conf

type into file:

options psmouse proto=imps

in terminal:

sudo modprobe -r psmouse
sudo modprobe psmouse

close terminal, log out, Fn+F7 should now toggle touchpad

got from this http://ubuntuforums.org/showthread.php?t=2020719&page=4

this solution works on Mint 14 (Ubuntu 12.10, linux version 3.5.0-21.32), and also with this solution scroll can be enabled.. just create a file:

/etc/modprobe.d/blacklist-acer.conf

containing this line:

blacklist acer-wmi

in terminal:

sudo modprobe -r psmouse
sudo modprobe psmouse

this solution works on 3.5.0-17.28, without needing to do steps above, just create a file:

/etc/X11/xorg.conf 

containing:

Section "InputClass"
    Identifier "ETPS/2 Elantech Touchpad"
    MatchProduct "ETPS/2 Elantech Touchpad"
    MatchDevicePath "/dev/input/event*"
    Driver "synaptics"
    Option "TapButton1" "1"
    Option "TapButton2" "3"
    Option "TapButton3" "2"
    Option "VertTwoFingerScroll" "1"
    Option "HorizTwoFingerScroll" "1"
    Option "CoastingSpeed" "10"
    Option "EdgeMotionMinZ" "30"
    Option "EdgeMotionMaxZ" "40"
    Option "EdgeMotionMinSpeed" "100"
    Option "EdgeMotionMaxSpeed" "400"
    Option "FingerLow" "9"
    Option "FingerHigh" "12"
    Option "EmulateMidButtonTime" "0"
    Option "ClickPad" "True"
    Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
EndSection

then, reboot..
