I'm using an external keyboard for my laptop. The keyboard (USB) does not have a suspend button. This means that I have to keep opening my laptop's lid (I don't want to do that very often as I'm also using an external monitor) in order to wake the laptop up from the suspended state.
Can I map some key combination to wake the laptop up from the suspended state?
Note that it may not be as trivial as it seems, as it has to work for waking the laptop up and likely Gnome shortcuts and similar things will not work. Likely it has to be some lower level thing, but what (if at all possible)?
PS: I'm using Ubuntu 11.04 64 bit
