Bug#682413: Possible solution.

[Barry Grumbine <barry.grumbine@campnavajo.com>]

I was having the same problem as you WRT: "The mouse cursor wanders
around a lot, esp. when a finger is resting on it, making precise
pointing infuriating."

I'm using the same hardware and kernel module.

$ uname -a
Linux CN212851 3.2.0-3-amd64 #1 SMP Thu Jun 28 09:07:26 UTC 2012 x86_64
GNU/Linux

$ lsusb |grep -i synapt
Bus 003 Device 004: ID 06cb:0009 Synaptics, Inc. Composite TouchPad and
TrackPoint

$ lsmod |grep synaptic
synaptics_usb          12912  0
usbcore               128498  5 ehci_hcd,ohci_hcd,usbhid,synaptics_usb



After configuring the trackpoint device's acceleration and deceleration,
I am no longer infuriated.  Try this in a terminal:

$ xinput list |grep -i trackpoint
⎜   ↳ Synaptics Inc. Composite TouchPad / TrackPoint    id=10   [slave
pointer  (2)]
⎜   ↳ Synaptics Inc. Composite TouchPad / TrackPoint (Stick)    id=11
[slave  pointer  (2)]


(Stick) is id=11

xinput --set-prop 11 'Device Accel Constant Deceleration' 3

xset m 5 1

If this helps you (and others) too, perhaps the module dev(s) could make
these the default settings for trackpoint devices.
