The saga continues :-) So, a combination of things seems to have given me the two monitor output i wanted. i had to edit my XF86Config, not the xorg.config file... I told it I had 2 video cards, and configured a monitor for each... then I manually added in the MergedFB options and restarted X. It works... sort of. My fonts are out of control now. Firefox fonts are HUGE... about 64 point. Seems only to be related to Firefox and Mozilla apps... and only in the application fonts (the title bar, menus etc.). Any ideas why?
Solved it by changing the dpi setting for screen 0. I doubled the width setting and restarted X and the font sizes returned to normal. Whew... not easy to get this silly thing "working" But it is working now.... Thanks for all the hints and tips. The combination of them all led to the solution. C
