  1. Enable SHMConfig in your xorg.conf file. Press Alt+F2. It will bring you the Run Application dialog box.
  2. Type following and hit enter:
    gksu gedit /etc/X11/xorg.conf
  3. It will ask you for your super user password. Give it!
  4. xorg.conf should open in gedit file editor
  5. Look for following lines:
    Section “InputDevice”
    Identifier “Synaptics Touchpad”…

    EndSection
  6. Add the following line just before the line EndSection
    Option “SHMConfig” “true”
  7. Save the file
  8. Open a Terminal
  9. Type the following command
    syndaemon -d -t -i 5
    -d runs the command in background
    -t disables only tapping and scrolling but not mouse movements
    -i sets the idle time in seconds after the last key has been pressed. The default is 2 seconds. I was convenient with 5 secs. It means if I don’t press any key for 5 secs, the touchpad will be enabled.

Now to run make the command as a startup command follow the following steps:

  1. Go to System>Preference>Sessions
  2. Click on Add button.
  3. Fill up the following data in the dialog box that appears:
    Name: { Name of the command such as: Disable Touchpad }
    Command: syndaemon -d -t -i 5
    Comment: { Any comments such as: Disables touchpad’s tapping functionality while typing }
  4. Click on OK and Close the Sessions dialog box

Enjoy tapping less typing 😉
