I think most people (at least myself) have moved beyond a mactel with
linux, which may explain inactivity. I still think it's an outstanding

Thanks for the quick update. Hope someone can figure it out.
On my macbook what happens is once one finger is on the pad it will still react
with movement when the second finger is put onto the pad or taken off the pad.
So unless you place both on and off together you get the jumping movement. Wh
Sorry, nothing has changed. I think we'd need someone with more experience
with weighting touchpad sensor values. The current algorithm just isn't
working right. Either this is only a very specific problem to only a few
hardware configurations OR I'm just so used to smooth apple trackpad in OS X
I just installed Lucid on my macbook 4,1 and have this issue with 2
finger scrolling. To annoying to use it with this bug, a real shame
since everything else works as expected.
Is there any status updates on a fix. I am willing to test things if
needed.

Some more details:

- jumping does occur from diagonal top-left, as well as from the diagonal
bottom-left, towards the center of the pad.

Hi, in fact, the Multitouch feature works perfect in the MacBook Pro 5.3,

What if you do the following:
1) Put your left finger on the left half of the trackpad
2) 1 second later, put your right finger on the right half of the track pad
Does this cause a jumping of the cursor? If so, this is what would cause the
scrolling issue. If not, the two-finger scrolling issue m
I cannot confirm this behaviour on the Macbook Pro 5,1 (currently using
Kubuntu 9.10/ 64-bit with mactel support). Scrolling with two fingers is

I just wanted to give a use-case/scenario where this is disruptive.
First of all, keep in mind that all Apple laptops only have one button
so the only option besides using two-finger click right clicks is to
bind keys with xmodmap (kind of an annoying necessity and not good for
user experience).
Two users independently confirm, and Ubuntu Forums have many reports.

The two-finger problem is just as bad with scrolling turned off. Two-
fingers + click is the default way of getting a right click on this one
button touchpad. The jumping pointer makes that unusable.
Is there something I can add to get this bug confirmed?

The jump happens during the context switch from one-finger pointing to
two-finger pointing. The reference point changes from the location of
the one finger to mid-way between the two fingers. The arrow should not
move when the second finger is added or removed. That's why it scrolls,
