Thanks for this (below) - it's really helpful.
[The clickpad acts *only* as 3 big buttons (L,Mid,R) over the entire zone;
it ignores any form of 1/2/3 finger movements or taps].

Is there any way to combine it with EmulateWheel, so that a middle-button
press, combined with a trackpoint-movement will give Hor/vert scrolling?

I normally use xinput to do this, but it isn't supported:
THE_ID=11   #use xinput list to find this on your machine.
xinput set-prop $THE_ID "Evdev Wheel Emulation" 1
xinput set-prop $THE_ID "Evdev Wheel Emulation Button" 2

Thanks,

Richard


P.S. Also, I've appended my own trackpoint.sh, which may be helpful to
those who would like to make the pointing stick a bit more sensitive. The
negative-inertia setting is worth experimenting with: it effectively
prevents overshoot.

touch. Default: 128

#Note that the TP also supports an optional "press-to-select" feature,
where tapping it acts like a left-click. This is the "press_to_select"
control in the same directory.
