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.

I attach two videos, one demonstrating pointer controlled via touch screen and touch pad, respectively. Note the pointer jumping in small steps when using the touch pad.
