Trackpoint and Touchpad on Thinkpad X300

[dmpogo]

X300 has trackpoint and touchpad. TouchPad works fine except for tapping (tap and drag).
But Trying to make trackpoint to scroll, I found that 3 buttons under trackpoint are
actually being driven by Touchpad synaptics driver. I.e if I disable Touchpad, all 5 buttons are disabled, if I don't load
Touchpad at all, then trackpoint is working but not 3 buttons below it.

Any ideas ? Besides scrolling which I would like to depend on middle button, I like switching off TouchPad when I am typing,
but no I loose all the buttons if I do it.


The only way to have just working TrackPoint with 3 buttons is to disable TouchPad in the BIOS.
But under Windows everything looks fine - middle button starts scrolling regime.

I'm using xf86-video-intel-2.5.0 and xf86-input-synaptics-0.15.2-r2
Trackpoint is driven by mouse (or evdev, results are same) driver, TouchPad - by synaptics.
I have checked with "synclient -m" that when Touchpad is enabled, upper butons generated generate synaptics
events, same as lower ones.

My config (here TrackPoint always scrolls, irrespectively to middle mouse pressed or not).
