Description

The elantech driver provides enhanced touchpad support for all EeePC models. It extends the standard psmouse.ko module to support new Elantech extensions.

The elantech driver was written by Arjan Opmeer and is currently being merged into the upstream Linux kernel (ETA, 2.6.28).

Current version in the eeepc kernel is v5

Setup & Installation

This driver is disabled on the eeepc kernel by default. To enable it, follow this procedure:

1. Update /etc/X11/xorg.conf to add synaptics' "SHMConfig" option.
   sudo gedit /etc/X11/xorg.conf
   Modify the "InputDevice" and "ServerLayout" sections to look like this. You may need to add them in if they're not already there.

   Section "InputDevice"
   	Identifier	"Configured Mouse"
   	Driver		"synaptics"
   	Option		"SHMConfig" "true"
   EndSection
   
   Section "ServerLayout"
   	Identifier	"Default Layout"
   	Screen		"Default Screen"
   	InputDevice	"Configured Mouse"
   EndSection

   Confused? Here's a completed xorg.conf with the appropriate changes.
2. Edit /etc/modprobe.d/eeepc to enable elantech option on the psmouse module:
   sudo gedit /etc/modprobe.d/eeepc
   This file may or may not already exist. If it does, append the following line to the bottom.
   options psmouse elantech=1
3. Install the special gsynaptics-elantech package. This package was originally produced by asus but its also available on the array.org repository.
   sudo apt-get install gsynaptics-elantech
4. Reboot.

  Applied elantech patch again, this time added a new module parameter to
  psmouse.ko. Only if "elantech=1" will the new elantech code be used. This
  code is off by default.
