touchpad disabling button requires workaround

[Yuriy Kozlov]

Binary package hint: xserver-xorg-input-synaptics

Hardware: Asus V6J laptop with synaptics touchpad

Problem: There is a button on the laptop to enable and disable the touchpad (not an Fn combo key). This button does not work in a default installation.

Workaround: Add
Option "SHMConfig" "on"
to the InputDevice section for Synaptics Touchpad in xorg.conf
This makes the button work correctly, and works for Dapper, Edgy, and Feisty.

This option should be enabled by default for at least this laptop.

Confirming, this is an issue for me as well.

Any idea which application handles that button? It should be fixed to use input device properties.

my enable/disable button doesn't work either. i'm using a compaq cq50 laptop with an amd chip and an nvidia chipset.

i'm using 64 bit and it hasnt worked on 9.10, 9.04 and 8.10.

would be really nice if i could just push a button and turn this thing on and off!
