fglrx, dual monitor = no double buffer !

[Mr. Ulmo]

Hi.

I'm having a little bit of trouble getting fglrx working properly.

When xorg.conf is configured to use only one monitor conky works with double buffer.

But when I've configure it to use both my monitors, conky fails to set up double buffer.

xorg is loading the double buffer extension automatically, if it helps i can post my config and my log file.
