T440s / T450s Trackpoint / Trackpad issue

[Ludacrisvp]

Hey Rehabman

I've recently upgraded the trackpad in the T440s to the trackpad from the T450s.
Both are Synaptics touchpads, just the T450s trackpad has the touchpoint buttons on it and clicks differently rather than being spongy...


Anyways I was hoping that you might know how to fix / adjust some of the behavior I'm seeing.

When I use tap to click it seems that quite frequently the cursor will move before it clicks (probably .25 inches) so as you might imagine that makes using tap to click rather difficult.

The top 3 physical buttons for TrackPoint don't work properly... All 3 of them act like a double right-click, as in the context menu briefly appears and disappears. When I had TrackPoint on the T410 the left and right keys did double click as well but at least they were the correct function, not just all right click, and the middle button functioned as a typical middle mouse wheel click (I used it to open and close tabs in chrome / safari).

Do you have some ideas on how to fix the jumpy cursor movement on tap to click?
Any thoughts on correcting the TrackPoint buttons so that at least the middle button will function as a single 'middle click' rather than a double right click?

Someday, I'll implement a threshold of movement/time before recognizing movement. But it is not implemented right now. If you happen to move slightly while tapping, it will count as movement.

The top 3 physical buttons for TrackPoint don't work properly...

You would need to debug the kext to see what is going on as far as packets/input received.

Also, I don't really know what you mean by "3 physical buttons" for "TrackPoint"... The trackpoint is the red nub, no? Hard to imagine three buttons on the top of that thing...

That would probably help but I swear I'm not moving. I never had an issue with the clickpad with the jerky motion. Perhaps it's just going to be a bit of a learning curve.

I'll switch over to the debug build of your voodoops2 kext and see what it shows.

Lol yes that would be something to have 3 buttons on that little nub.

The buttons with the red lines and little blue dots are intended to be used while you are using the trackpoint so you don't have to reach all the way down to the bottom of the touch pad to click those buttons.

New pad has 3 real buttons at the top of the trackpad:

Old pad has 3 virtual buttons at the top of the trackpad which don't work at all in OS X:

 

[RehabMan]

So the buttons are on the trackpad, not trackpoint.

Good luck with the debugging.

Well this wasn't what I expected to see....

I pressed and released spacebar in between pressing the 3 touchpad buttons.

[RehabMan]

Further analysis of the passthru packets required. Buttons are being sent via passthru protocol.

I was hoping you would've come back to elaborate on this a bit ...
How to I do that?
Would I be able to bypass the passthru protocol to have voodoops2 handle things?
Or would that cause other undesirable behavior?

At the very least I'd like to get the middle click button to work as I prefer opening links in new tabs but the website I use for work seems to override the 'open link in new tab' behavior of cmd left click but when using another machine the middle button mouse click always opens it in a new tab and I also like using it to close tabs.

With the cursor movement on tap to click .. it seems that if I really lightly tap the touchpad it doesn't move the cursor, if I have too much force in the tap then it moves more frequently. So its probably just something I'll get used to dealing with.

Side note:
The trackpad does have a virtual right click button in the bottom right corner too that does work properly.
I'd assume that if passthrough mode was disabled this would not work?

You should read the spec from Synaptics.

I added some passthru support based on what the spec said, but some laptops seem to implement it differently.

Hi Ludacrisvp,
have you managed to solve the trackpad issue (especially the dragging and random movement during the tap)? Searched for the solution and it appears where're not the only one (https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller/issues/65).... if not, how to you work on your unit?

No. I just learned to live with it. However I don't really use this machine anymore as I've been using a mid-2014 MBP retina 15" for the last several months.
