Dual Monitors w/ Fedora 3


I have a dual head 6600Gt (agp), and I have 2 monitors hooked up to it. They were flawlessly in windows, but I cant gettem to work in Fedora Core 3. I have the Nvidia drivers installed. My second monitor is just black. In my xorg.conf file my card is reading as a single head card. How do I configure my dual monitor settup? Here my xorg.conf file, incase you need it.


# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
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"
EndSection

Section "Module"
Load "dbe"
Load "extmod"
Load "fbdevhw"
Load "glx"
Load "record"
Load "freetype"
Load "type1"
Load "dri"
EndSection

Section "ServerFlags"
Option "AllowMouseOpenFail" "yes"
EndSection

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"
#
Identifier "Keyboard0"
Driver "kbd"

Xorg provide xinerama to get 2 distincts desktop or one large.

Nvidia drivers provides twinview, an equivalent wich can work also.


Try to find tutorial, some are well made. I managed to get xinerama running for some months, it wasn't so hard but i dont remember how to get it running.

good luck

How did you plug your second monitor to your card?
If you can see the text of the console (ctrl-alt-F1) on both screen, your monitor is correctly connected and its an Xfree problem. If so, try this howto : http://www.tldp.org/HOWTO/Xinerama-HOWTO/

If no, there's a prolem. And i dont understand why its working in windows and not in linux. Sorry

Before I installed the nvidia drivers the screens were mirrored. The same thing on both screens. After I installed the nvidia drivers only one screen shows stuff, the other is black. I have the second monitor pluged into my video card using the adaptor it came with.

In this case, maybe you need to get another version of the nvidia driver.
It isnt normal that the screen dont get mirrored in console mode. I dont speak for graphical interface for now, just in console (at bootup for exemple)

Oh wait, it does mirror in consol mode, like at boot up. Just not when it gets into x, then it only shows up in one screen. Is there a way i can make x read my card as a dual head card?
