Ubuntu 14.04 entirely does not see a touchpad with its buttons on my Dell Inspiron 14 3000 laptop. Re-installed Ubuntu - result is the same - no touchpad. I ran some diagnostics and here are the results:

xinput:

  • I was asking for help but got that abracadabra instead. Is it a usual way to respond in this community?

Pour votre information et si qqn est amené à requérir votre aide sur le touchpad, voici comment résoudre le défaut.

Ce problème se règle assez facilement, quand on sait quoi faire ! Il faut ajouter une ligne à un fichier de configuration pour “blacklister” un certain pilote, qui entre en conflit avec la reconnaissance du touchpad. La procédure est simple, il suffit d'ouvrir le Terminal (depuis le menu Unity, taper “terminal” pour retrouver l'application et la lancer) et de copier-coller la commande suivante (évidemment, appuyer sur Entrée ensuite)

In terminal, run:

echo "blacklist i2c_hid" | sudo tee -a /etc/modprobe.d/blacklist.conf

Then restart and the touchpad should work properly.

    I can confirm that this works with Ubuntu 14.04.1. I don't know why someone else down voted it.
