You can (1) disable it (completely) in the BIOS (probably); (2) turn it off by running
Code:
synclient TouchpadOff=1
in, say, your
.profile or, (3) if you're using KDE, you can add the following to
~/.config/autostart/synclient.desktop
Code:
cat ${HOME}/.config/autostart/synclient.desktop
[Desktop Entry]
Version=1.0
Type=Application
Name=SynClient
Exec=synclient TouchpadOff=1
StartupNotify=false
Terminal=false
Hidden=false
This entry will, when KDE starts.
All but the BIOS method the touch pad will be "hot" until one of these are executed (so, basically, you need to curl your fingers to get started).
(3) above with thanks to Robby Workman.
Hope this helps some.
