Err, I meant "Device" section not "Screen", but I think Kerry is right:
going back to i810 is a good idea.

Hi Roy,
forget about xrandr for now :)
in your "Screen" section in xorg.conf add:
Option "Clone" "off"
and restart xorg.
cheers

Firstly, thanks all for the advice on the hardware acceleration front.
I couldn't get it working, but that has been superseded by another

Based on this thread, I've switched from i810 to intel driver (can't
get dual monitors working, but I'll get back to that).
So, having just obtained a second monitor and card to drive it I'd
like my desktop spread over the two screens. I'm not well-skilled in
the intricacies of X.
Things I've tried:
The howto at Ubuntu Forums
http://ubuntuforums.org/showthread.php?p=2545824 didn't work for me.
The most useful-sounding suggestion for getting dual monitors working
is at http://burtonini.com/blog/computers/randr-2007-02-06-17-50 but
no joy there either. The appropriate tip in the Ubuntu Hacks book was
not useful.
I've installed xrandr 1.2 for the extra goodness it provides. "xrandr
--fb 2800x1050" gives me a dual-screen-sized desktop but (here's the
problem) the monitors are cloning each other and always show the same
half of the available space. This occurs regardless of the various
xrandr --output TMDS-1 --pos 0x0 --left-of VGA --auto
and
xrandr --output VGA --pos 1400x0 --right-of TMDS-1 --auto
instructions I issue.
The output of "xrandr --verbose" and my current xorg.conf (and some
other possibly-irrelevant files) are at
http://users.actrix.co.nz/roy.barb/dual/
Various other permutations of xorg.conf have had similar effect, so
long as the "Virtual 2800 1050" line is retained in the Display
subsection.
It'll be real nice to have dual displays working well. I'm happy to
take suggestions or to appropriately compensate a knowledgeable lister
for their time.
Cheers,
Roy.
