How do I enable horizontal scroll on lubuntu desktop

Question

I have Ubuntu 13.10 installed with the Lubuntu desktop installed. On the Ubuntu desktop two finger horizontal scrolling works fine but when I log into my preferred lubuntu desktop two finger scrolling only works with vertical scrolling and I cannot find an option to change it.

Answer 1

The setting should be:

synclient HorizTwoFingerScroll=1

if you have a Synaptics touchpad. To make the changes permanent, see this answer.
