Matrox G550 Dual Head on Suse 10.0


I have recently been trying to enable dual head working on a Suse 10.0 (64 bit) system using a Matrox G550 dual head card. In order to acheive this I edited the 'xorg.conf' file in /etc/X11 and by virtue of including additional sections for devices, monitors and screens and finally updating the 'ServerLayout' section was able activate dual head working. However, only one screen (the leftmost - device[0]) receives a video signal on starting the system. To bring the other screen into life I've found that the following procedure has to be followed:

1. Activate YAST

2. Select Hardware, and then "Graphic Card and Monitor". The window correctly has tabs for each display and and another for alignment.

3. Click 'OK'. A 'Final Steps' popup is now shown. On it click the 'test' button. The second screen is now activated, shows video and mouse correctly moves between screens. Shortly afterwards a window is shown in the middle of each screen to enable refinement of sizes. Each window has a 'save' and 'cancel' button.

4. Click on any of these buttons. If you click 'save' there is a message saying that changes will be activated on reboot.

5. Cancel or click OK out of all windows and you can continue working in dual head mode.

However, even if settings are saved at step 4 on reboot dual screen working is enabled but screen 2 (the right hand screen) has no applied video and the above procedure has to be followed every time to restore dual head working. Moving the mouse / windows previous to carrying out the above procedure shows that system beleives 2nd (right) screen is activated. So my question is "How can settings be establisshed such that at boot-up the 2nd screen has video activated?" Attached below is a copy of my xorg.conf file.

Any guidance anyone can give me on how to remedy this situation would be much appreciated!
