Left clicks work. Right/middle do not (as expected, I guess).

I liked the behaviour of Takashi's patch a little better wrt what
happens when you try to click/drag, because he disabled movement
in the click area.

My vodka consumption is minimal and I don't have the shakes, but
I found it difficult to precisely hit the edge of a window and
click / drag to resize...

No.. Synaptics without right button == ClickPad.

Driver still takes options, from UDEV/HAL. We could pick one behavior
by default and ovverride, by box vendor/model (DMI).

Hopefully vendors won;t be flip/flopping between ClickZone and
ClickButtons too much. Still option is better than hardcoding ClickZone
for everyone.

Are the clicks register only in that special area? Reading Synaptics
product description it sounds like entire surface should be clickable.

So, is there only Clickpad device that has a single button?
No other option?

Yeah, I agree that hard-coding isn't good, and that's why I first
posted separated patches. OTOH, the kernel-side hack makes the device
working *as is* even without changing anything else.

I have not seen any other Synaptics devices using less than 2 buttons.

For "ClickZone" - yes, but not all users would want this I guess and not
all laptops will have that zone marked. Pushing it off to userspace
gives more flexibility, including the ability to change zone size, etc.
