Hi,

I tried to setup Dual Head with Ubuntu 8.04 (Xorg 7.3+10ubuntu10.1), a
Radeon 9250SE card and two 1280x1024 TFTs connected to the VGA and DVI
ports of the graphics card.
(Ubuntu's configuration tool, displayconfig-gtk, does not work properly.)

I am using the attached xorg.conf, and executed the following command:
xrandr --output VGA-0 --left-of DVI-0

As soon as I did this, the monitor connected to the VGA port got black,
and the DVI monitor was only partly usable. One half of the DVI monitor
and the complete VGA monitor didn't display anything except the still
movable mouse pointer. The other half of the DVI monitor still displayed
all windows and was usable without any problems.

Could anyone point out a solution for this?
Thanks for your help.
