[ubuntu] Touch pad slow/freezes, and scroll doesnt work

view story

http://ubuntuforums.org – Hi everyone. I just installed Ubuntu on my HP Dv4 2153cl and i'm having some issues with my touch pad. the mouse is not moving as fluid as it does in Windows and randomly freezes. Also, my touch pad scrolling is not working. Hope someone could possibly help me out with my problem, I'm still new to Linux (but still glad i've made the switch). Thanks! (Hardware)
