Binary package hint: xserver-xorg-input-synaptics

The lower 1/4 - 1/3 part of the my touchpad doesn't not produce cursor movement, nor events in xev & evtest.
Horizontal scrolling is not functional and can NOT be enable in gpointing-device-settings.

This is on a Lenovo Thinkpad X100e Laptop, running ubuntu 10.10 maverick AMD64 - a clean install - 
This Synaptic touchpad is fully functional -ie. not a hardware issue - as it is working quite well on Lucid 10.04 LiveCD.

I presume it is coordination bug as the Y-axis reported back from the
touchpad ranges from ~700 - 4400. X-axis is fine.

I have another old Toshiba Satellite A55 running 32-bit ubuntu 10.10 and
its ALPS touchpad is OK.
