Dual Monitor Support


I have an NVIDIA GeForce FX5600 graphics card that has dual monitor support. I have my two monitors plugged in. They work fine until I get to loading X when the second monitor cuts out. It is probably a problem with my XF86Config file, in my opinion. Here it is:

# XFree86 4 configuration created by redhat-config-xfree86

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "DevInputMice" "AlwaysCore"
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"

# 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"

There is a very long readme file which was installed with the nvidia driver. It has XF86config-4 configuration examples. The nvidia driver has it's own options that get entered to the XF86config-4 file that may be different. You need a second 'Monitor' section for the second monitor and have the layout defined.
I think the file is in the /usr/share/doc directory. If you enter the command find /usr -name "NV*" you should be able to find it.

You need the second screen line here and if you want to change where it gets displayed you can use RigthOf, Above and Below in the line. If this does not solve the problem then keep reading because I needed to do the rest.

You should use the proper refresh rates for the monitor not some generic settings.

Here you should have a second card section (Videocard1) with a BusID or at least it is needed for my two card setup you may want to do a bit of searching on that or go to a console login and change to the /root directory stop the X server on Debian I would do that by /etc/init.d/kdm stop you may be able to do similar and then X -configure and check for the proper settings in the XF86Config.new that is created you may even want to use that file as a base if the test that it tells you how to do works well.

Here depending on the result of the video card settings the Device "Videocard?" in the Screen1 will change.
