Not sure. That's handled by apci, not the video driver. You can check it the lid is producing proper events by running: cat /proc/acpi/button/lid/LID/state with the lid open and closed. The desktop manager decides what the policy is for the lid (blank display, suspend, turn off the connector, etc.). It should also take into account other connected outputs, but I don't think it handles that too well at the moment.
