LinuxQuestions.org - dual screen no longer works after FC6 upgrade

I had dual screen working in FC5, but after upgrading, it no longer works. Even trying to set it up via system-config-display does not work. Here's my xorg.conf from FC5:

Code:

# Xorg configuration created by system-config-display



Section "ServerLayout"

        Identifier    "Multihead layout"

        Screen      0  "Screen0" LeftOf "Screen1"

        Screen      1  "Screen1" 0 0

        InputDevice    "Mouse0" "CorePointer"

        InputDevice    "Keyboard0" "CoreKeyboard"

        Option      "Xinerama" "on"

        Option      "Clone" "off"

EndSection

# Multiple FontPath entries are allowed (they are concatenated together)

# By default, a font server independent of the X server is

# used 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"

So that one above worked under FC5, but not FC6.

and here's my attempt to make it work with FC6, I didn't copy it wholesale since 1) it didn't work this way and 2) there have been some things removed from xorg.conf in FC6

Code:

# Xorg configuration created by system-config-display



Section "ServerLayout"

        Identifier    "Multihead layout"

        Screen      0  "Screen0" LeftOf "Screen 1"

        Screen      1  "Screen1" 0 0 

        InputDevice    "Keyboard0" "CoreKeyboard"

        Option        "Xinerama" "on"

        Option        "Clone" "off"

EndSection



Section "Files"

        ModulePath  "/usr/lib/xorg/modules/extensions/nvidia"

        ModulePath  "/usr/lib/xorg/modules"

EndSection



Section "Module"

        Load  "extmod"

        Load  "glx"

EndSection



Section "InputDevice"

        Identifier  "Keyboard0"

        Driver      "kbd"

        Option      "XkbModel" "pc105"

        Option      "XkbLayout" "us"

EndSection



Section "Device"



#added by me

        Identifier  "Videocard0"

        Driver      "nvidia"

        Option      "AddARGBGLXVisuals" "True"

EndSection



Section "Device"

        Identifier  "Videocard1"

        Driver      "nvidia"

        BusID      "PCI:1:0:0"

        Screen      1

EndSection



Section "Screen"

        Identifier "Screen0"

        Device    "Videocard0"

        DefaultDepth    24

        SubSection "Display"

                Viewport  0 0

                Depth    24

                Modes    "1280x1024" "1280x960" "1280x800" "1152x864" "1152x768" "1024x768" "800x600" "640x480"

        EndSubSection

EndSection



Section "Screen"

        Identifier "Screen1"

        Device    "Videocard1"

        DefaultDepth    24

        SubSection "Display"

                Viewport  0 0

                Depth    24

                Modes    "1280x1024" "1280x960" "1280x800" "1152x864" "1152x768" "1024x768" "800x600" "640x480"

        EndSubSection

EndSection

and finally, here's my current working setup - which only works for one monitor.

Code:

# Xorg configuration created by system-config-display



Section "ServerLayout"

        Identifier    "single head configuration"

        Screen      0  "Screen0" 0 0

        InputDevice    "Keyboard0" "CoreKeyboard"

EndSection

        ModulePath  "/usr/lib/xorg/modules"

EndSection



Section "Module"

        Load  "extmod"

        Load  "glx"

EndSection



Section "InputDevice"

        Identifier  "Keyboard0"

        Driver      "kbd"

        Option      "XkbModel" "pc105"

        Option      "XkbLayout" "us"

EndSection



Section "Device"

EndSection

        Identifier "Screen0"

        Device    "Videocard0"

        DefaultDepth    24

        SubSection "Display"

                Depth    24

                Modes    "1280x1024" "1280x960" "1280x800" "1152x864" "1152x768" "1024x768" "800x600" "640x480"

        EndSubSection

Any help would be greatly appreciated! I really like having dual screen and I feel so limited by not being able to re-enable it.

Thank you!
