Dell Latitude D630 touchpad “jumping” mouse cursor

A friend and I have been discussing an issue we’ve both been seeing on our laptops: The mouse cursor “jumps” when using the touchpad. It’s intermittent, unpredictable, and seemingly random, but it seems to jump about 3 inches straight up on the screen. It seems to happen only on Windows-based OSes; We both installed Ubuntu Linux at a point and didn’t notice it at all.

He pointed me to the R165805 Dell Touchpad / Pointing Stick driver from the Dell website.

I am using it on a D630 with Windows 7… it works, and solves the problem.

The listed compatibility is:

Systems Latitude D530
Latitude D630c
Dell Precision Mobile WorkStation M2300
Operating systems Microsoft Windows Vista 64-bit

Update 2/10/2013: gund brought to my attention that the download link is no longer active. Here is a direct link to the R165805.EXE file on Dell’s FTP site. If that ever becomes unavailable, you can try this driver, but I haven’t tested it myself: R165804 Dell Touchpad / Pointing Stick.

 

I’ll welcome any comments on this.
