Two-Finger Scrolling in LXDE (Ubuntu 12.10)

I can't get two-finger scrolling to work in LXDE w/ Ubuntu 12.10.

Here's a brief history. I upgraded my machine (an old Dell Inspiron 1200) from Ubuntu 10.04 LTS to Ubuntu 12.10 all in one fell swoop, and then installed LXDE and completely removed all ubuntu-desktop packages using the psychocats instructions (because I greatly dislike Unity). In short, it's more or less basically like Lubuntu now, as far as I can tell. All other programs and settings work just fine -- but not two-finger scrolling.

Help?

(Oh, and there will be bonus points for anyone with right ideas about how to enable "natural scrolling" after I get the two-finger scrolling working!)

I found an answer here and have summarized it below.

TWO-FINGER SCROLLING

Create and/or edit a file called mouse.fdi like so:

sudo leafpad /etc/hal/fdi/policy/mouse.fdi

Paste in this stuff:

<?xml version="1.0" encoding="ISO-8859-1"?>

<deviceinfo version="0.2">

 <device>

  <match key="input.x11_driver" string="synaptics">

   <merge key="input.x11_options.VertEdgeScroll" type="string">true</merge>

   <merge key="input.x11_options.HorizEdgeScroll" type="string">true</merge>

   <merge key="input.x11_options.MaxTapTime" type="string">0</merge>

  </match>

 </device>

</deviceinfo>

Save! Reboot! Done!

BONUS: "NATURAL SCROLLING"

Enable "natural scrolling" (AKA "reverse scrolling") by creating a file in the home directory called .Xmodmap like so:

leafpad ~/.Xmodmap

And paste in this stuff:

pointer = 1 2 3 5 4 6 7 8 9 10 11 12

Save! Reboot! Done!

DOUBLE BONUS: DISABLE TAP-TO-CLICK

Open the session autostart file:

sudo leafpad /etc/xdg/lxsession/Lubuntu/autostart

And append this stuff (or simply run it from the command line for a one-off solution):

synclient MaxTapTime=0

Save! Reboot! Done!
