How to use tpconfig
tpconfig is currently supported as a command-line configuration tool. The PS/2 port does not currently support sharing. Therefore the tpconfig utility will not work while any other mouse driver is loaded (gpm). This also means that you cannot use tpconfig while X Windows is running. The suggested use of tpconfig is to run it from a startup script ('touchpad' .. installed for run leves 3 and 5 and provided in the rpms) before gpm is started.
I usually run tpconfig from a start-up script which (on my RH system) goes in /etc/rc.d/init.d (and linked under various run levels as S84touchpad) to turn off the tap mode. Installation of this script and links for run levels 3 and 5 are now performed by the binary rpm.
Always make sure to give execute permission to the script whereever you put it.
