Default Strange touchpad acceleration behavior with Dell Mini 9 - 07-01-2009, 04:07 PM

[Note: I previously posted this on ubuntuforums, but I'm also posting it here because I'm not getting much help there.]

I have a Dell Mini 9 running Ubunbtu Jaunty (9.04), and I'm having some issues with the acceleration behavior of the touchpad.

What works: When I move my finger slowly, the cursor also moves slowly. When I move a little faster, the cursor accelerates; that is, moving the same physical distance on the touchpad results in the cursor moving farther.

What doesn't work: When I move my finger very quickly, instead of accelerating even more, the cursor moves more slowly. (By "very quickly", I mean I move my mouse across the entire touchpad in maybe .5 sec.)
I can't say for sure, but seems like I'm moving too fast for the touchpad is to register. I don't think it's a hardware problem, since acceleration behaves as expected in Windows XP.

As a result of all of this, I find it really annoying to use the touchpad -- this is especially salient because I've been using a new Macbook Pro where the touchpad moves the cursor exactly where I want it to go without me having to think about it.

I tried installing the gsynaptics package and playing with the max speed, but it doesn't seem to help.

Any ideas on how to fix this?

I've found that playing with balancing the speed and acceleration settings in the standard mouse setup (not gsynaptic) will usually give me the results I am looking for. It's just a matter of finding the best balance between the two. I generally set my speed all the way down and my acceleration up about 25% from the lowest setting.

I'll try that out when I'm back by my Mini again, but I strongly suspect that this won't fix the issue -- the problem is not that the cursor speed maxes out; it's that it actually slows down the faster I go.

For example, if I move my finger all the way across the touchpad at medium speed, the cursor moves about 3/4 of the width of the screen. But if I move my finger at high speed, the cursor will only move 1/8 of the screen.

I've had some what I thought was some strange touch pad behavior with my Mini 9. So I appreciate the tips given here. I've changed the mouse settings and the problems seem to be gone. So far so good.
