Hi,

I am running a new Dell Latituted E6530 and I ran into the problem
described in this thread on Ubuntu 12.10 64-bit.

Unfortunately, I have to report that Dave Turvene's kernel patch
candidate did not work for me (or only in a limited way). However, Ben
Gamari's patch did do the trick for me. So, Dave, I fear your patch does
not work for the E6530 yet. I will gladly help you fixing this by
testing other variants of your patch on my laptop or provide you with
the output of some command or other. Just tell me what you need.

In more detail:

First I tried out Dave's patch. I followed exactly Harish's instructions
of comment #242.

This was only a partial success.
Afterwards, I finally had a "Touchpad" tab under "System Settings->Mouse and 
Touchpad". However, neither edge-scrolling nor two-finger-scrolling worked. 
Although I could now enable both of these options, they did not actually 
_work_. It still simply wouldn't let me scroll, even though I enabled both 
options (in turn).

I stress that my touchpad was correctly recognized:

$ xinput -list
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ DualPoint Stick                           id=12   [slave  pointer  (2)]
⎜   ↳ AlpsPS/2 ALPS DualPoint TouchPad          id=13   [slave  pointer  (2)]
[snip]


So, I decided to give Ben's patch a try. I followed exactly useResa's 
instructions posted at
http://resalxh.wordpress.com/2012/09/18/ubuntu-12-04-lts-x64-the-next-step-getting-touchpad-working/

This worked like a charm! :-)
I can now choose between edge-scrolling and two-finger scrolling. Both are 
working.
It leaves a slightly bittersweet feeling though, since Dave's patch which will 
(or has?) be(en) submitted as a kernel patch candidate does not work. Can we 
fix this? I will help out as best I can.

On a side-note, "horizontal two-finger scrolling" does not work with
either Dave's or Ben's patch, but who needs that? ;-) (the pointer will
jump around wildly if I try this with Ben's patch). Horizontal edge-
scrolling does work with Ben's patch.

In any case, kudos to Dave Turvene and Ben Gamari for their work, as
well as Harish and useResa for their helpful comments!

Cheers,

Malte
