Paul - I did copy your file and loaded the module but it failed to work - in fact it even stopped the touchpad cursor movement altogether! I returned to the psmouse-elantech package from AUR, built the package and then installed it with pacman -U - and hey presto it gives the correct behaviour in terms of touchpad tapping, as well as vertical scrolling - it will need to be rebuilt each time there is a new kernel until kernel version 3.3 is released but at least I now have a working touchpad on the laptop so I can live with the small inconvenience of rebuilding the module periodically in the interim. Thanks for the input. -- mike c
