XF86 config Problem - Redhat 9

 
G'day
 
I am yet another Linux newbie on the long and arduous path to salvation
from the rancid world of Microsoft and I can't get my !@#$%^ monitors to
work properly. I have just installed the XF86 that comes with Redhat 9.
So whatever the version that is, that's the version I have. However, I
have managed to modify the XF86Config file so that a signal is sent to
all three monitors but am having a few problems. I do know that the
system works fine under Mandrake Linux 9.0 so it may not be an XF86
problem.
 
I have 3 monitors all using the nvidia driver (1 NVIDIA AGP and 2 TNT
pci types). Though the monitors work, the mouse will not traverse the
screens Also if I use the xinerama option I get the same image (complete
with the active mouse) on all three screens and not one large virtual
screen.
 
HELP!!
