I just installed Ubuntu 14.04.1 on my Acer Aspire E5 but the touchpad doesn't work. This is the result of xinput:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ USB Optical Mouse                         id=12   [slave  pointer  (2)]
⎜   ↳                                           id=14   [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)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Power Button                              id=9    [slave  keyboard (3)]
    ↳ Sleep Button                              id=10   [slave  keyboard (3)]
    ↳ Power Button                              id=11   [slave  keyboard (3)]
    ↳ HD WebCam                                 id=13   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]
    ↳ Acer WMI hotkeys                          id=16   [slave  keyboard (3)]

(the third should be the touchpad).

This is from my /proc/bus/input/devices file:

I: Bus=0003 Vendor=06cb Product=2970 Version=0111
N: Name="   "
P: Phys=usb-0000:00:13.0-1/input0
S: Sysfs=/devices/pci0000:00/0000:00:13.0/usb4/4-1/4-1:1.0/input/input13
U: Uniq=
H: Handlers=mouse1 event13 
B: PROP=1
B: EV=b
B: KEY=e520 10000 0 0 0 0
B: ABS=260800000000003

If I press Fn+F7 nothing happens (though if I press any other Fn+F* it works correctly).

I already followed instructions on these links but still doesn't work:

Why does the Touchpad of Acer Aspire V3-551G not work on Ubuntu?
touchpad is not detected in ubuntu 14.04 on acer aspire one AO756
Ubuntu 13.04: Problem with the Synaptics touchpad on a Acer Aspire One ZG5 (AOA110) not detected (can't find Synaptiks on software center!)

Can anybody help me?

For me the easiest was to update to 14.10 but the right click is missing. Or if you are more advanced user update the kernel to 3.17-4*. The device is still Unknown.

...after a year and a half, new version (16.04) resolved the issue.
