That depends on which pre-compiled packages you're using. I don't recall if 
distro was mentioned, but the RH/FC packages from ATrpms all come with xrandr 
support enabled now.

KDE here.

Ah, I was wondering how the hell I'd done that on a few occasions myself... 
Good to know. (Now I vaguely recall seeing something about it in the 
past...). My only other problem is that occasionally, when dumping out of a 
high-def stream (xrandr'd to a 1080i mode) and flipping back to the GUI (in a 
540p mode), the left edge of the UI starts in the middle of the TV and wraps 
around to the other side, but is rather dark and blurry/jagged, or something 
like that. I think someone just submitted a patch for that today though...
