    I am having trouble getting dual monitors working with RedHat Fedora Core
    Release 2. I have had them working with red hat 9 and windows 2000. I am
    trying to get xinerama working (one big desktop) across two screens.
    Although I cannot get clone working either. Although my ATI 7000 card is a
    dual head card I want to use seperate video cards. (I want to eventually
    have 3 monitors)

    I have tried a variety of things. The main monitor works and the display
    config utility says everthing is fine but the screen does not turn on and
    the mouse will not leave the main screen. Each one works by itself
    (configured properly). I have my xorg conf file as below. I have been trying
    to get this going for 2 days now, any help is appreciated.

    # Xorg configuration created by system-config-display

    Identifier "Default Layout"

    Screen 0 "Screen0" LeftOf "Screen1"

    Screen 1 "Screen1" 0 0

    InputDevice "Mouse0" "CorePointer"

    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"

    # 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"
