Touchpad cursor jumps around
When using the touchpad on my Vostro 1500 with Hardy, my cursor will regularly jump around the screen. Frequently if I continue moving my finger, the cursor will jump right back to where it should be, sometimes it will continue along in its new random location. I feel like this has gotten worse in the last week.
I have tried disabling the horizontal and vertical scrolling. I have played with the sensitivity and acceleration to no effect. And I have been very careful where the rest of my hands are as I use the touchpad. Even with no other part of my hand near the touchpad aside from my finger, this will still happen.
Does anyone else have this problem? Is it a problem with the Linux driver? Or could it be a hardware malfunction? Or is it probably me? I don't have my Windows partition working right now for testing because I blew it messing around with the Media Direct functionality. Any thoughts or suggestions would be appreciated.
