[ltp] UltraNav on new T30s?

[Pam Huntley]

Hi,

You're right, with both mice active, the linux driver doesn't know how to
handle the third button on the trackpoint.  This is because the trackpoint
is actually a guest mouse that gets passed through the touchpad, and the
data is encapsulated kinda weird.  Synaptics has been so kind as to make
the specification for this pass-thru protocol completely open, so there
should be some fixes for this soon.   If you're a developer and you want
the right contact at synaptics, I think I can also give you that, if you
email me directly (I need to check with him first, but it should be fine).
Right now, the only way to get the third button working is to disable the
touchpad, which makes the trackpoint behave like normal.

Pam

I just got a new ThinkPad T30 a couple of days ago.  One of the
issues with it is that I cannot get the middle mouse button on
the integrated "UltraNav" pointing device, which incorporates
both a TrackPoint and a touch pad, to work properly.  In fact, if
I do a hex dump of /dev/psaux to the console, nothing at all
registers when I repeatedly click the middle button.

Unfortunately, the UltraNav protocol is not the TrackPoint
protocol at all.  In fact, it is almost, but not quite, the
protocol used by Synaptics TouchPads, which makes a bit of sense
because at least the touch pad part of the UltraNav was designed
by Synaptics according to a Synaptics press release.  But the
Synaptics protocol doesn't have anything in it about enabling or
disabling a middle button, so it's not too helpful.

Has anyone had any luck with the UltraNav?  Or can anyone give me
a contact at IBM?  I've already emailed Synaptics, but not
received an answer, and so I'm starting to wonder if trying IBM
is a better bet.

Thanks,

Ben.
