           Summary: Dual Head doesn't work with xorg 1.6 (One screen blank
                    or Clone)
           Product: xorg
           Version: 7.4

xorg log after reboot. Last lines might be there because of switching to
console (CTRL-ALT-F1)

(xserver 7.4, radeon 6.12.2, kernel 2.6.29)

After upgrading to xorg 1.6 (xserver 7.4) my dual head configuration stopped
working.
After reboot, only one of my two screens is working (not at 
default mode 1280x1024 at 85 but 1280x1024 at 60). The other one stays blank
(powersave)
xrandr tells me both screens were connected and set to 1280x1024. 
Manually trying "xrandr --output DVI-0 --left-of DVI-1" or vice versa
switches screens, so the other one gets blanked.
In KDE, running Display Settings, there are two screens shown, but
pressing "identify screens" shows both, DVI-0 AND DVI-1 on the working
screen. Also the image (in KDE Settings) only shows one screen with DVI-0 
and DVI-1 written in it.
After some time, when both screens go in powersave mode, waking them makes 
both work, but in clone mode.
