Close lid on laptop with FC4 without going to sleep

[Espen Stefansen]

I got a laptop that i just installed FC4 on and that i want to be up
and running all the time, with it's lid closed. The problem is that
every time i close the lid, it goes to "sleep". So i cant ssh to it or
anything.

What i want is that when i close the lid, the screen just goes
blank/black. but i can still ssh to it, or use vnc to use the desktop,
cos there will always be a user logged in.

Is this possible?

Regards
