dual screen with ATI Radeon 9550??

[Radscientist]

I've just finally gotten DVI-I to VGA adapter for my ATI Radeon 9550 and now both monitor shows the same things. How would i make it so i can have 2 seperate desktop for each of the monitors?

EDIT: adding this code of my XF86Config-4 files so maybe u can figure something out.

Take a look at this site: http://linuxgazette.net/124/smith.html. It may not be exactly what you want, but he's touching on the multi screen system.
