I've gotten the S3 to behave itself and I now have a three monitor
display! XF86Config-4 file in line at the bottom of this message for
those interested.

I do have some problems:
1) Usually, all the Gnome stuff (panels, menus etc) are on the left ATI
display and the right ATI display has none of this stuff on it. With the
below configuration, the panels spread across both ATI displays and the
Gnome stuff is replicated on the S3 display. I would like there to be no
stuff (don't you like the technical term?) on the S3 display and all the
Gnome stuff still only on the left ATI display.

2) xscreensaver only activates on the left ATI display and the S3
display - not the right ATI display. (I know this is related to the
Gnome stuff being shown on both ATI displays.)

3) The S3 works fine under Windows (WinXP Pro is installed on the first
partition) so I know the h/w is capable of doing this, but in X I
haven't been able to find the correct Sync & Refresh rates to get a
stable 1280x1024 (16 bit) happening. At 60/70 max Hz respectively, the
S3 driver chops down to less than 1280x1024 and it looks weird having
different resolutions on three identical 17" LCD monitors. So I'd like
to have the S3 display at 1280x1024 without flickering horizontal lines.

Any ideas or tips gratefully received.

Thanks,
Greg
