Clone monitor with ATI's fglrx

[ocgltd]

I'm running ATI's latest driver (May 31 2007) on linux 2.6.20 with an ATI X1600 video card.

I am trying to clone the two video outputs, but can only get side-by-side (extended desktop) to work. My xorg.conf is below. Can someone see anything that should be changed to enable cloning?

Thanks,
Michelle

Why you have two ServerLayout sections is beyond me. Besides, did you notice how it says "Screen 1 "aticonfig-Screen[1]" RightOf "aticonfig-Screen[0]"" ? I'd assume it has something to do with the "extended desktop" you talk about. The RightOf is a dead give-away for me...

If you have only one screen section (not to mention one ServerLayout), then Clone mode should be on by default (just restart your x server).

Try amdcccle next time. It has nice, click-able interface.
And you're posting in the wrong section.
