Mark Richard and other trying their best to help me!!!,

It seems that I am so near - yet so far so any help woudl be gratefull received!

Here are the answers to what is installed on my machine as far as I can tell!

Restricted Drivers manager lists two drivers:

Lucent/Agere linmodem controller driver
NVIDIA accelerated graphics driver

Both are ticked as enabled.  Nvidia has green "button" for In use.

Synaptic Package manager tells me:
I have installed:
nvidia-glx NVIDIA  -  binary XFree86 4.x/X.Org driver
nvidia-kernel-common  -  NVIDIA binary kernel module common files
xserver-xorg-video-nv - X.Org X server -- NV display driver. The notes say, "This driver for the X.Org X server (see xserver-xorg for a further description)provides support for NVIDIA Riva, TNT, GeForce, and Quadro cards.

Note that this is not the same as the binary-only 'nvidia' driver, which
adds 3D support, but is binary-only and not supported."

The relevant bit of my my xorg.conf is:

Section "Device"
    Identifier     "NVIDIA Corporation NV34 [GeForce FX 5200]"
    Driver         "nvidia"
EndSection

Section "Screen"
    Identifier     "Default Screen"
    Device         "NVIDIA Corporation NV34 [GeForce FX 5200]"
    Monitor        "Generic Monitor"
    DefaultDepth    24
    SubSection     "Display"
        Depth       1
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       4
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       8
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       15
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       16
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       24
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
EndSection

Section "Extensions"
    Option         "Composite" "Disable"
EndSection


I notice that Composite is Disabled. I bet it is not a simple matter of changing that entry!!

As you asked:

The web suggest:

sudo apt-get install nvidia-glx
sudo nvidia-xconfig --add-argb-glx-visuals --composite

and no I have not done that yet

Richard - I can get Beryl Manager to run, (Alt-F2 did not work for me so I used a terminal) and all the settings look good and fun - but I can find no way to activate it! I think I am back to this "Composite Extension not available" One of the settings if I right-click the red diamond is, "Select Windows Manager" It was on "Metacity - Gnome Windows Manager" I changed it to Beryl, the screen flashed a bit as open windows were ? redrawn, but to no avail. It went back to "Metacity .."

Thanks in advance for any help

It never is :-)

I'm going to try a new install of 7.04 over the weekend on one of my
work desktops, if I'm allowed into work over the weekend. That's a
fairly standard box with an Nvidia card so should be a reasonable test.

The restricted drivers section tells me that I do have NVIDIA
installed and working.  However, the web suggests:

What exactly does it say?

I have to say I find the restricted drivers tool very confusing and I'm
never quite sure what it means, because:

I note from Synaptic I have "NVIDIA binary XFree86 4.x/X.Org driver"
installed.

That suggests you have the FOSS driver installed, not the Nvidia binary.

If you look in /etc/X11/xorg.conf, which driver is it loading? I suspect
is has the nv driver (FOSS), not nvidia (proprietary binary)

You can install the right driver through synaptic, but I suspect you've
got the wrong one because it's not really clear which is which. have you
tried:

sudo apt-get install nvidia-glx
sudo nvidia-xconfig --add-argb-glx-visuals --composite

.. yet?

Alternatively, find the nvidia-glx package through synaptic and see if
its installed. I'm sure(ish!) I didn't need to manually configure the
driver, so I think you just have the wrong one installed (like I said
it's not obvious which is which, they're both labelled as nvidia
drivers). Don't uninstall the FOSS driver though, its useful if you have
problems to be able to switch back to it (usually manually editing
xorg.conf as root and changing nvidia to nv is enough, which is very
handy if something breaks; it's happened to me once).
