Linux Opensuse - Acer Aspire 5349 disable touchpad mouse

Hi guys,

Pretty much I've just fished out an old laptop and installed OpenSuse on it, the problem is that the left and right mouse buttons on the touchpad keep sticking and causing me no end of grief, when I get round to it I'll lift the mouse button and spray some canned air in there and that will probably fix it, for now though I just want to completely disable the mouse buttons and touchpad, could you please guide me through this?

I've got to System Settings > Touchpad and it says:

Hardware information: SynPS/2 Synaptics TouchPad and gives me a few options, there doesn't seem to be an option to disable the touchpad though....

Thanks.
