--- Comment #28 from Juan Ramón Molina Menor <info at juanmolina.eu> ---
Hi again.

> Could you do following gestures and post results here:
>
> Gest 1.
> 1. Put first finger on e.g. left bottom corner of TP
> 2. Do a short move so cursor moves too
> 3. Put second finger on opposite corner
> 4. Move both fingers to trigger 2finger scroll
> 5. Release first (left) finger but leave second on TP
> 6. Move second finger across TP
>
> Gest 2.
> 1 - 4 is the same
> 5. Release second (right) finger but leave first on TP
> 6. Move first finger across TP

Results:

--- Synaptics ---
Gest 1 and 2: Cursor does not jump on p. 5. Scroll stops in p. 6 and cursor
resumes moving.

--- Elantech ---
Gest 1: Cursor jumps on p. 5. Scroll stops in p. 6. and cursor resumes moving.
Gest 2: Cursor does not jump on p. 5. Scroll stops in p. 6 and cursor resumes
moving.


> Could you post synaptics "dmesg" and "sysctl hw.psm." output here too?
