Bug#682413: Possible solution.
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
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
$ lsusb |grep -i synapt
Bus 003 Device 004: ID 06cb:0009 Synaptics, Inc. Composite TouchPad and
$ 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
⎜ ↳ 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.
