Bug Description
Binary package hint: xorg
Release: Jaunty Beta
xorg version: 1:7.4~5ubuntu18
xfree86-
When using the touchpad on my Eee PC 900A, the cursor will often (say, 50% of the time) jump when I tap-to-click. It does the same when moving the pointer across the screen, if I get to an edge and have to start back in the middle.
It usually jumps horizontally or vertically about 100 pixels, but some times it jumps a long way diagonally, putting it in a corner of the screen.
For the most part it seems to jump in the direction of the last place I touched on the touchpad.
This touchpad worked perfectly under 8.10. I also saw this when using xfree86-

Additional information:
I tested this on an Acer Aspire One, an Emachines 6809 and a Zoostorm laptop. All of these models have a Synaptics touchpad ('dmesg | grep input' shows Synaptics Touchpad) and none of them exhibit the jumping behavior.
On my Eeepc 900A, the touchpad is listed as "ETPS/2 Elantech Touchpad".
