Disable suspend on lid close but still turn display off

Hi, so today I got my brand spanking new Dell Studio 16 XPS and so far it and Fedora 13 seem to be a match made in heaven. Everything just works out of the box: wifi, bluetooth, 1920x1200 display, webcam, special keys, audio, suspend & resume. Awesome! What I'm wondering though is how I can make the notebook just disable the display when I close the lid instead of completely suspending. I'm planning to use this system as my main system and to attach a larger LCD screen and keyboard externally. I then just want to put it closed at the back of the table however right now it just suspends so I can no longer use it. Is there a way to turn on some kind of "docking mode" to disable the display on lid close but otherwise leave the system running normally? Regards, Dennis
