Second Monitor Not In XConfig?


hey...im using dual 17 inchers with a ti4400 gforce. I installed the latest drivers, edited my xconfig, but my second monitor aint showin up. I tried disconnecting each monitor and starting up, they work peachy. I read thru the xinerama howto but there both the monitors are detected. Any help? thanks for your time ppl

here is my xconf
# XFree86 4 configuration created by redhat-config-xfree86

Section "ServerLayout"
Identifier "Multi Head"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
RgbPath "/usr/X11R6/lib/X11/rgb"
FontPath "unix/:7100"

Section "InputDevice"

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"

Section "Monitor"
you are supposed to have 2 of these:

Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unprobed Monitor"
HorizSync 31.5 - 72.0
VertRefresh 50.0 - 130.0
Option "dpms"
EndSection

like this:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unprobed Monitor"
HorizSync 31.5 - 72.0
VertRefresh 50.0 - 130.0
Option "dpms"

Identifier "Monitor1"
VendorName "Monitor Vendor"
ModelName "Unprobed Monitor"
HorizSync 31.5 - 72.0
VertRefresh 50.0 - 130.0
Option "dpms"
EndSection

name the second one monitor1 or something. try it.
also DUPLICATE any other monitor0 reference with monitor1

You will need to define a Screen section for each monitor. You have one screen section already. What you need to do is make the first mode on the Modes line be "1152x864" followed by the modes already their.

A Monitor section defines the monitor or LCD. A Device section defines a graphics adapter. The Screen section ties an adapter to a monitor and defines what modes, color depths, frequencies, etc the combination can use.

Finally, the ServerLayout section ties together the input devices witht the screens, and how the screens are placed relative to each other.

Not that difficult once you get the hang of it.
