Hi,
I used my radeon dual DVI card up to F7 without any problems in MergedFB mode as one big screen (xinerama). In Fedora 9 MergedFB mode is gone and replaced by randr compatible configuration. I figured out how to modify xorg.conf.
My current state is:
- as soon as graphical boot screen comes up I can move the mouse from one screen to the other and back, it is, it feels like xinerama, but only one screen is used for messages - OK
- when gdm starts I have one big screen as expected - OK
- after login the display switches to cloned configuration - Problem
- I can manually switch to one big screen (xinerama-like) using xrandr --output DVI-0 --right-of DVI-1
Obviously I have missed something in my configuration file. Please, could someone have a look on it?

There is no error message in Xorg.log but an information:
Any help greatly appreciated. (==) No monitor specified for screen "Default Screen". Using a default monitor configuration.
If I add a monitor option it makes no difference.
