I installed Ubuntu 11.10 on the Acer S3 ultrabook and I am trying to get the touchpad to work with two button scrolling. When I go to System Settings -> Mouse and Touchpad I don't see any touchpad preferences there, only basic mouse settings.

When I run xinput I get the following:

 Virtual core pointer                           id=2    [master pointer  (3)]
    Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
    PS/2 Elantech Touchpad                      id=11   [slave  pointer  (2)]

Does anyone know how to get the touchpad working ?

First off does the touch-pad support two finger scrolling? If so the result of synclient -l would be nice to edit

add the output of the command synclient -l.

You can change the setting of the synclient by adding to the startup application a new application with the following command:

xterm -e synclient "EmulateTwoFingerMinZ=10"

This would change the setting of EmulateTwoFingerMinZ to the value of 10

1)Click the top-right icon of your desktop and select "System Settings"

2)Click the "Mouse and Trackpad" icon

3)Go to "Touchpad" tab, check the "Two-finger scrolling" option and check "Enable horizontal scrolling"

Now you must have two finger scrolling.. :)
