Ubuntu – Touchpad stops working after login


My gf's touchpad has started acting funky since she hooked it up to a projector. It works alright on startup, but as soon as she gets out of the login screen, the cursor freezes up and she has to use a USB mouse.

I saw another thread for the same problem here, but none of the five solutions seemed to work.We're in 12.04

The following is adapted from the OP's comment. It is a very similar technique, but not in the OP's own words.

  1. Install dconf-tools Install dconf-tools:

    sudo apt-get update && sudo apt-get install dconf-tools
  2. Open dconf Editor by pressing Alt+F2 and running dconf-editor (Or run it in a terminal.) or search for it in the Unity Dash.

  3. Go to:

    setting → org → gnome-settings-daemon → peripherals → touchpad

  4. Set the key touchpad-enabled to true.
