Xubuntu 12.04 and Nvidia 7300 multi-screen

After installing Xubuntu 12.04, on my old PC with a Nvidia 7300, only the monitor connected to the VGA port was displaying X. The DVI side stayed dark.

I have created a minimalistic /etc/X11/xorg.conf :



Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection


And used nvidia-xconfig to customize it using :

# nvidia-xconfig --twinview  --twinview-orientation="LeftOf"

My DVI monitor (the second one) is on the left of my VGA Monitor.

That's it.
Then I have logged out and in and I got both monitors on and windows sliding between them.

For reference here is my working xorg.conf :


# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 295.40  (buildmeister@swio-display-x86-rhel47-06.nvidia.com)  Thu Apr  5 22:40:54 PDT 2012
