After a logout / login I give the command:
xrandr --output DVI-0 --right-of VGA-0
Now the display is in dual head mode. Because the total display size of the radeon7000/ve card is smaller than the 2048x768 virtual desktop the right side of the desktop isn't refreshed. I had a work around by opening a permanent firefox browser on my right monitor.
When you put the xrandr statement in the .profile the dual head is always enabled when you log on.
