Disable touchpad when the lid is closed

I have my notebook configured in a way that when the lid is down, the computer does nothing. No lock, no logout, no suspend, nothing.

But, It seems like the touchpad interacts with the screen and that messes up everything. Everything is messy, folders starts to open, clicks everywhere, etc.

I'm able to fix the problem following these steps: https://askubuntu.com/questions/91534/disable-touchpad-while-the-lid-is-down but I think It'd be great if this solution came by default with the OS.
