I'm being really lazy here I know, but so far in my 5 minute search of
the web I've found info on setting up two monitors with xinerama by
manually configuring XF86config-4.  I suspect however that there is
nice, easy Mandrake gui method.  If so, can anyone point me at it?
I have added a second video card and attached a monitor to it.  Mandrake
sees both cards, but if I run XFdrake and tell it to test, it just tests
the active one without noticing which card I've chosen.  So I guess
that's just talking to the X server and the X server hasn't noticed the
second card.
I'll start hacking at XFconfig86-4 if that's what's required, but if
there's a tool that does it right...
   

OK, decided to give it a go and followed the howto.  Now both monitors
are working, but xinerama isn't - the second monitor just repeats the
image of the first and the mouse doesn't go there.
I clicked on the enable xinerama button in KDE configuration and
restarted X, but still no go.  I have attached my XF86Config-4 file. 
Can anyone see what I've missed?

thanks
Brian

IIRC there should be a line in the server layout section that reads 
something like:

Option "Xinerama"

or

Option "Xinerama" true.

Better have another look at the howto.
