Two-Finger Scrolling in LXDE (Ubuntu 12.10)

Solution 1:

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!
