[Trisquel-users] Power saving - how to enable touchpad?

[nimrod7]

When Trisquel is in power saving mode my touchpad stops working. How can I  
configure settings to have touchpad always enabled?

I've managed to fix similar issue with mouse editing  
/etc/laptop-mode/conf.d/usb-autosuspend.conf, but I've no idea how to do that  
with touchpad.

Info: input: ETPS/2 Elantech Touchpad as  
/devices/platform/i8042/serio1/input/input9
I've Trisquel 6.0.1.
