Some Vaios come with both integrated and discrete graphics, plus a
switch for choosing one of the two. When the switch position is
changed, a notification is generated, now forwarded to userspace for
example for visual notifications, user scripts, and so on.

shouldn't this be reported as an input event rather than just an acpi
one?

If so, please someone let me know which keys to use.
