On Ubuntu OS, if I touch the touchpad, the cursor arrow would dance around, and do the continuous left-click operation. If I don't touch it, it won't move and click.
Though seems trembling randomly, it jumps towards the right side of the screen by 1/6 of the screen width from time to time.
This thing happens in about 50% chance when I boot the Ubuntu.
The arrow works normally when using usb mouse. And both of touchpad and usb mouse are always fine in Win 7.
I'm newbie to ubuntu, what should I do ?
