I installed Ubuntu 13.04 x64-amd on my Acer Aspire v3-471G laptop. The touchpad wasn`t working since I started the installation process from a USB flash device using Pen Drive and continue to be not functional after successful installation. I updated the system but nothing got it worked.

Using command xinput list to list the available connected device, it shows the following

Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Genius 2.4G Wireless Mouse                id=12   [slave  pointer  (2)]
⎜   ↳ ETPS/2 Elantech Touchpad                  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)]

    ↳ HD WebCam                                 id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]
    ↳ Acer WMI hotkeys                          id=15   [slave  keyboard (3)]

I couldn`t find any solution online. I appreciate any help here :)

@Yahya's solution worked, but with one extra step.

I went to BIOS, set touchpad to basic. At first it did not work, but when I activated the touchpad using Fn+F7, it started working.

I just solved it by changing touchpad from advanced to basic in the main tab of the BIOS settings.

You can access BIOS by turning off the laptop, and then turn it on again and press F2 after the ACER logo shows up.

In my case xinput list did not contain the touchpad, and the following method by @Noxet got the touchpad working again:

The solution: add i8042.nopnp to the kernel command line. To do this:

sudoedit /etc/default/grub

and add:

GRUB_CMDLINE_LINUX="i8042.nopnp"

If there's already a line with GRUB_CMDLINE_LINUX=…, add i8042.nopnp inside the quotes, separated from any other word within the quotes by a space, e.g.

GRUB_CMDLINE_LINUX="some-other=option i8042.nopnp"

Then run

sudo update-grub

and reboot. Hope it works, it worked for me!

I think the problem is of during installation.Use universal usb installer instead. It works like a charm for me and even recommended by Ubuntu's official USB mouting guide.

Below is the link for it: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/

The chances are that you have already found a solution. But just in case, I'm providing another answer. My laptop is the same make and I faced exactly the same problem (along with inactive brightness keys and overheating).

This solution for the touchpad issue was not my creation. But here it is:

  1. Using a terminal navigate to /etc/modprobe.d/:

    cd /etc/modprobe.d/

  2. Open the file options.conf with your favorite text editor (I'm using gedit):

    sudo gedit options.conf

  3. In the text editor, type:

    options psmouse proto=imps

  4. Save the file and close it.

  5. Run the following commands:

    sudo modprobe -r psmouse
sudo modprobe psmouse

I do hope the solution works for you. It worked like magic for me. (would have shared the link with you, but I don't seem to have it).

I thank the people who authored this and the other solutions that makes Ubuntu run in ACER Aspire v3-471G.
