In your udev dump I see two devices which represent the touchpad and the
trackpoint:
P: /devices/pci0000:00/0000:00:1a.1/usb4/4-1/4-1.4/4-1.4:1.0/input/input29
E: NAME="Synaptics Inc. Composite TouchPad / TrackPoint"
E: EV==17
E: KEY==70000 0 0 0 0 0 0 0 0
E: REL==3
E: MSC==10
P: /devices/pci0000:00/0000:00:1a.1/usb4/4-1/4-1.4/4-1.4:1.1/input/input30
E: NAME="Synaptics Inc. Composite TouchPad / TrackPoint"
E: EV==17
E: KEY==70000 0 0 0 0 0 0 0 0
E: REL==3
E: MSC==10
As you can see, both have identical KEY and REL capabilities, so it's
impossible to tell apart which is which.
Decoded:
REL_X, REL_Y (which is typical for a mouse, and okay, although misleading,
for a touchpad).
BTN_LEFT, BTN_RIGHT, BTN_MIDDLE (also typical for all kinds of mouses)
However, neither has ABS (absolute coordinates) capabilities, and so far
we consider a device a touchpad only if it has ABS_X/ABS_Y and
BTN_TOOL_FINGER and not BTN_TOOL_PEN ("pen" would mean it's a tablet).
So this is either a kernel bug, or the device just physically acts like
a simple mouse. Does it help to forcefully overwrite the x11_driver to
synaptics, i. e. can the synaptics driver make anything good out of
this?
