Thanks, I'll check out your howto!
I was under the impression that the new xrandr was meant to allow 
dynamic monitor switching. I really hate going through xorg.conf every 
time I want to plug/unplug a monitor. In F7, I've found a combination of 
fglrx/krandrtray/xorg.conf that lets me more or less switch between two 
configurations (lvds only vs. lvds+crt1)
