Mint 12: Can't Get Synaptics Touchpad Disabled

view full story

http://unix.stackexchange.com – I have tried everything I can find online (including here) and nothing will stick. The touchpad comes back to life after a few seconds. The Windoze driver had a disable-entirely option. I do NOT want to use the frakkin' thing at all, so anything up to and including a hardware fix is now open for consideration. The laptop is an HP Pavilion DM12 and the Linux is a fresh install of Mint Lisa (12) with GNOME. Suggestions? And yes, I tried everything here with NO repeat NO effect. (HowTos)
