Description of problem:
With the latest synaptics package, it is now very difficult to do small movements (e.g. for clicking a small icon or link), because the pointer keeps on moving while the finger rests on the touchpad.

This is shows in synclient:
$ synclient
...
    CoastingSpeed           = 0
    CoastingFriction        = 50
   PressureMotionMinZ      = format mismatch (32)
   PressureMotionMaxZ      = format mismatch (32)
    PressureMotionMinFactor = 0
    PressureMotionMaxFactor = 0
...

Notice the error with the PressureMotion settings.

Version-Release number of selected component (if applicable):
xorg-x11-drv-synaptics-1.5.99-7.20120207git141d9120b

Apparently a new type of properties was introduced, called cardinals.
These do not (yet) seem to be supported by synclient and xinput.

See this patch proposed in June:
http://lists.x.org/archives/xorg-devel/2011-June/023284.html
or in git:
http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/diff/?id2=6269fdaf3283ba4a8051858fc2b43fa102823e96

Which would explain the error I see in xinput:
Synaptics Pressure Motion (292):		... of unknown type CARDINAL
which may just be the meaning of "32" in synclient:
PressureMotionMinZ      = format mismatch (32)

I'm not an expert on X11, but XA_CARDINAL seems to be an integer, so
it should be fairly easy to add support. Or to revert back to
"integer" as a hotfix.
