Hi Seth,

I'd been considering switching to KDE anyway and after using it for the
past few days am getting used to it. It's really nice having
two-fingered scrolling.

Here are the things I've noticed about the driver:

* I occasionally get a stray palm press while typing, which switches the
focus or moves my cursor. The problem isn't nearly as bad as it was
before your driver. Previously, I used the patch from comments #307 and
#154 to disable tap-to-click and retain my sanity. Eliminating all stray
palm presses is my only real request about the driver.

* Two-fingered tap to right-click works, but is very difficult to get
right. I have to try several times to get a contextual menu to appear,
but then other times I accidentally invoke it. For now, I've disabled
this. I can never get it to detect a three-fingered tap. Neither of
these are big deals for me.

* I just now mastered tapping the corner to right click (for me it's set
to bottom right corner). I have to tap and lift immediately. Still, a
little tricky to get right (tap and lift seems to help with two fingered
tap too).

* When I hold my finger to the touchpad, the pointer quivers slightly. I
believe you mentioned that this behavior would be improved in Oneric
(I'm using Natty).

* Horizontal scrolling with two fingers works. Single fingered scrolling
on the bottom edge invokes vertical scrolling however (left = down,
right = up). Strange, but not a big deal since two fingered horizontal
scrolling works.

* I thing "Horizontal circular scrolling" is working: if I start at any
edge and move at an angle, I get vertical scrolling.

* I can't seem to get "Continue edge scrolling automatically" to work
(e.g. I have "Continue edge scrolling, while the finger stays in an edge
corner" checked but that doesn't happen, but I'm not confident I'm doing
it right).

* "Continue cursor motion when hitting the touchpad edge" works just fine.

Thanks so much for working on this. It was depressing to have this fancy
touchpad and have to use it with such limited functionality. Let me know
if there's anything I can do to help you in your debugging efforts.

Kind regards,
David
