What could cause this sporadic cursor problem? I've got this problem where my cursor is jumping left and right all on it's own. I'm not touching the computer at all, I've rebooted the system, and the only way to get it to stop is to use a mouse and disable the trackpad when a mouse is connected.

Here is a video showing the problem

Seems I had damp fingers when using the trackpad. Caused the sporadic issues for about 3 days. Then it all went away.
