Touchpad scroll not working on HP Pavilion dm3 laptop [closed]

I have an HP Pavilion dm3 laptop running Ubuntu 11.10. My touchpad works perfectly fine, but with one exception, the scrolling does not work. Does anybody out there know of any sure-fire fix that exists out there?

The following commands fixed it for me (temporarily until reboot):

sudo rmmod psmouse
sudo modprobe psmouse proto=imps

And to make it permanent

sudo gedit /etc/modprobe.d/options

Add this line:

options psmouse proto=imps

Note: This fix will make the touchpad be recognized as a mouse instead, which will remove some features specific to touchpads such as disable while typing.
