Description Erich Schubert 2012-02-20 01:50:38 UTC

The synaptics Pressure Motion option was changed from float to CARDINAL 32:

http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/commit/?id=a24c44375025576dd600ccf370ba365e5d94dc22

However, neither synclient nor xinput do yet seem to support this:

xinput:
Synaptics Pressure Motion (292):		... of unknown type CARDINAL

synclient:
  PressureMotionMinZ      = format mismatch (32)
  PressureMotionMaxZ      = format mismatch (32)

the easiest way of solving this for now would probably to revert back to an integer value for now. The cleaner way to add support for cardinal typed atoms to synclient and xinput.

This probably is the reason for bug #45278
because judging from the report, the pressure motion settings show the same issue. So he might just be seeing pressure motion in effect (which btw. is very annoying if you have a sensitive touchpad ...).
