Ok. None of your logs seem particularly suspicious, and I'm unable to
reproduce this locally.
Could you please install the evtest and xinput packages, and run:
sudo evtest /dev/input/event7
and attach the output, then run
xinput test SynPS/2 Synaptics TouchPad
and try to move using the
For those who need to use their touchpad while we work out what's
happening, here's a quick downgrade script that will temporarily drop
you back to the previous versions of the X server, synaptics, and evdev.
Caution: this will break apt - “sudo apt-get -f install” should get apt
to upgrade back

attaching evtest (not sure if any use) and the xinput, well no need, nothing
happens, ie.
doug@doug-XPS-M1330:~$ xinput test SynPS/2 Synaptics TouchPad
that's it

So, an evtest listing of sabdfl's touchpad which also exhibits this problem is:
~/ $ sudo evtest /dev/input/event7

Input device ID: bus 0x11 vendor 0x2 product 0x7 version 0x1b1
Input device name: SynPS/2 Synaptics TouchPad

What is a bit weird - did a reboot, re-ran evtest and got this
doug@doug-XPS-M1330:~$ sudo evtest /dev/input/event7

It would be very helpful to be able to replay events from an affected
device on a different computer. This is possible using utouch-evemu.
Please do the following:
1. $ sudo apt-get install utouch-evemu-tools
2. Determine the /dev/input/event* node for your synaptics trackpad
- You can search
Here is a possible fix for the problem, for someone with 64bit. The
package contains a tiny patch which makes utouch not interfere with
traditional semi-mt touchpads. Please report back here.

For those interested, you can reproduce this issue by running:
1. $ sudo evemu-device device.prop
- This will create a new /dev/input/event* node for the virtual device
2. $ sudo evemu-play (/dev/input/event* node from step 1) device.record

It appears this is a bug triggered by a multi-finger, non-mt trackpad.
Trackpads that do not give the number of fingers on the surface and
multitouch trackpads are unaffected.

I verified that the fix in the debian package resolves the issue, so
Bilal, if it does for you too, a new package will be on its way shortly.

We're getting multiple confirmations of this bug.
Most likely culprit is the multitouch patches that went in today.
I've re-tested today's latest bits on three laptops all running natty,
but can't reproduce the problem. Either it's HW-specific, or there's
some other aspect / configuration
Next action for testers would be to attempt downgrading to the previous
xserver. RAOF, would you mind outlining exactly what packages should be
downgraded? (Attaching a bash script might save some re-typing).
