ThinkPad with ALPS? Should not be it Synaptic? Maybe
miss-detection?

Sorry, I forgot to mention this. The ThinkPad came with a clickpad
I **really** disliked, so I bought this on the Internet.

So, here is a problem. ThinkPads works with Synaptic touchpads, not
with ALPS.

There definitely seems to be a problem here :)

Do you mean that the alps code might not be detecting the trackpoint
because probably the red thingie works with synaptics?

So could this be the situation:
ALPS driver: Hey touchpad! Do you have a trackstick?
ALPS touchpad: No, I don't.
AD: Ok! (and thinks 'I am going to have to ignore all trackstick
packets that might arrive')

So the driver understands that there can't possibly be any buttons
because there is no trackstick?

IIRC ALPS touchpad hardware itself does not work with non-ALPS 
trackpoint.

Masaki, any comments?

If by trackstick you mean the red thingie, it is **not** working.

Ok. And it is working with your patch?

No, it isn't :(

I expected... You just created franken-hardware.

Looks like with your hack patch it is possible to make buttons working, 
but I suspect that trackstick would.

Maybe Masaki can provide more information about this fact if we can do 
anything.

Dmitry, what you as maintainer going to do with this problem?

It really depends on Ota-san response. If ALPS needs a special version
of firmware flashed for proper trackstick identification, then I guess
Juanito will have to carry a local patch. I do not think we want to
complicate the driver any further for supporting such after-market
modification.

If this only happens in this after-market (or franken-hardware...
hahaha), I'd totally understand if you didn't want to patch it upstream,
although it would be nice for me :)

Does booting with psmouse.proto=imps makes trackstick work?

I am afraid I can't test it now as I don't have access to the laptop. I
won't be able to test until two weeks. Will definitely do as soon as I can.

Thanks.

Thank **you** (Dmitry and everybody esle) for taking the time to look at
this.
