Nvidia TwinView not working

[hassantm]

Hi folks...

I'm new to linux and I'm trying to configure a dual monitor setup... I've finally managed to get my Nvidia driver working, but I'm having issues with TwinView. Both monitors are recognised during startup, but when X starts I lose one. I'm using 2 17" Sony SMD-X73 screens.

I've posted my XF86Config file if anyone can have a guess at what I'm missing. I've waded through google and various message boards, but I'l still at a bit of a loss and very confused!

# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
#

# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
#
# If you'd like to switch the positions of your capslock and

Thanks folks and sorry if this is an endlessly repeated question!

Not sure if this is part of the problem, but you have this..

Section "ServerLayout"
   Identifier     "Default Layout"
   Screen      0  "CRT-0" 0 0
   Screen       1  "[b]DFP-1[/b]" 0 0

DFP = Digital Flat Panel..trying changing it to CRT...who knows?
