GSynaptics is used to configure 'synaptics' touchpads
( there are also qsynaptics and ksynaptics which do a similar job).
To use any of these you need a line in xorg.conf which is :
option "SHMConfig" "true"
But when I try to run it I get the message:
GSynaptics couldn't initiaize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config

At the moment I have tapping disabled with
option 'MaxTapTime' '0'
Before using your patched kernel this was ignored and touchpad was
However, at the moment I do not know what parameters are available
when using the elantech touchpad.
If it helps I will try to find out more options and see what works.
Please note that even if nothing more can be done I would much prefer
what is available with this patch than anything else I have tried.
