Turn off touchpad tapping?

[tpprynn]

I've added lxde to Ubuntu 11.04. Though I have my touchpad tapping function turned off, when I boot lxde it's back on. I imagine that this can be switched off? Even if it's a file alteration somewhere.

What's the equivalent of gksu nautilus in lxde also? In other words, how to I open the file system as root?

Thanks.

gksudo pcmanfm should do the root filemanager. Can't help with the touch pad as I turn mine off in the bios.
