My laptop is an Acer 4741. It's running Ubuntu 11.10
When I worked on Windows 7, my touch pad had vertical and horizontal scrolling and multi-gesture. Both scrolling and multi-gesture aren't working on Ubuntu.
How can I get it to work?
Start the System Settings (e.g. via the button in the top right corner -> System Settings) and the go to Mouse and Touchpad. There select Touchpad. This tab offers you to enable two-finger scrolling and also horizontal scrolling.
