Hi!

When I'm using dock with external input devices (keyboard + mouse) and 
LID is closed, I'm getting spurious touchpad events and random mouse 
clicks and movements.

It is because top part of LID is above touchpad and probably generates 
touch pushes.

Year (or two?) when I had conversation with ALPS people I was told that 
Windows driver is automatically turning touchpad off when ACPI LID close 
event is received (and similarly turn touchpad on).

Maybe Linux should do similar thing? Random movement or touchpad clicks 
is really annoying. But I'm not sure if kernel or userspace should do 
this job... What do you think?
