I'm still trying to figure out why my laptop won't output X to my CRT. 
LCD screen is just fine, the CRT shows non-X boot/system stuff (so the 
connection is good). Went through some of the KDE GUI display settings, 
but one says I don't have Xfree 4.3 "the latest", so I can't resize. 
Unrelated? The KDE "Display" (system-config-display) UI lets you 
configure for dual head, but it just won't come through on the CRT.

My CRT is actually a NEC MultiSync 97F, but it wasn't offered. I also 
switched Xinerama to "off" and Clone to "on" and it still didn't work.

Here's my "xorg.conf" file:
-----------
# Xorg configuration created by system-config-display

Section "ServerLayout"
    Identifier     "Multihead layout"

    InputDevice    "Keyboard0" "CoreKeyboard"
    Option        "Xinerama" "on"
    Option        "Clone" "off"
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"
