Public bug reported:
In some of Dell laptops, they support a touchpad LED to indicate the
enablement/disablement of the touchpad.
And kernel(after 3.2) supports an interface to turn on/off the LED, user space
app should take the responsibility to handle this,
and I think gnome-settings-daemon is the best one.
The interface is in /sys
To turn on the LED
echo 1 > /sys/class/leds/dell-laptop::touchpad/brightness
To turn it off
echo 0 > /sys/class/leds/dell-laptop::touchpad/brightness
