Auto-suspend on lid close is a feature that I hate. Even on my work Windows laptop, I can never be sure that it will suspend, and half the time you wish it wouldn't because then your VPN connection will time out, etc. Thus people walking around with their laptop open a couple of inches. Much better to completely disable auto-suspend and get used to just pushing the suspend button and waiting the couple of seconds for it to react and then closing the lid.

That's the main reason I can't even be bothered to configure this (as in from the GUI) on my Linux machines.
