Title:
  Touchpad resolution too coarse on thinkpad X230

Status in linux package in Ubuntu:
  Confirmed
Status in xserver-xorg-input-synaptics package in Ubuntu:
  Confirmed

Bug description:
  The thinkpad X230 tablet has three HID for controlling the pointer: mouse, touch screen and touch pad.
  With mouse and touch screen as inpt devices, I have pixel-exact control of the pointer.

  In contrast, when using the touch pad as the input device, resolution
  is very coarse: the pointer jumps in small steps of approx. 5 pixels.
  This resolution is too coarse, e.g. for controlling graphical user
  interfaces with small buttons. Very often, when I tap on the touch pad
  for emulating a left click, the pointer jumps 5 pixels from where it
  was, causing me to actually click on a different button. (This can be
  quite annoying. Example: I regularly hit "suspend" instead of "log
  out" in the system menu).

  Can the pointer resolution be changed for the touch pad? If so, it
  should default to pixel-exact resolution.
