dual head on fedora

[Jim Patterson]

I was trying to set up a computer with dual head and install an ATI 9250 
AGP card and an ATI 9250 PCI card.  When I go to display and select Dual 
Head I can setup the card resolution and Color Depth and the monitor, 
but even after reboot the second screen still doesn't show anything.  It 
just stays blank.  Is there anything else I should look at.

following is xorg.conf

# RgbPath is the location of the RGB database.  Note, this is the name 
of the

# 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.

# 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"
