EDIT.2 (minimal tidy-up)

I bought my laptop with Windows 7 installed. The touchpad has up/down arrows on the right side, as if this would scroll. When I installed Ubuntu 11.10, I was able to use this touchpad scroll function.

I recently did an update (at some late hours) and i can no longer use right side of the touchpad to scroll.

Can anyone tell me how to get the same function as I had in Windows and Ubuntu 11.10 ?

I think I now have Ubuntu 12.04
