I do not know if this is a change in the way compiz/xorg handles windows in fc12, but when I use ctrl+alt+shift+[directional arrow], the command would be issued to rotate my screen and carry the active window with it.

I no longer have this functionality, and do not know where to start in retrieving this functionality

I do not know when this started. It either started in my upgrade from fc9 to fc12, or after applying this modification that I recieved from the forums ::
