Problem still present in Ubuntu 9.10 on my Samsung x118 (Synaptics touchpad).
But in 1 of 5 system boots two-finger scrolling works fine without cursor jumping.
In 4 of 5 cases cursor starts randomly jump on screen when I touch touchpad with two fingers.
I try to set synclient JumpyCursorThreshold=100
but it only decrease frequency of cursor trembling.
Two-finger scrolling doesn't work in that case.
