dynamic twinview switching with nvidia-settings

[jesso]

I have a 9500 GT with two LCD monitors connected and a HDTV via component output.

I want to use nvidia-settings to switch between 2 LCD and 1 LCD + HDTV, without changing xorg.conf and restarting kdm.

In nvidia-setting's under Display Configuration I see all three displays and the TV-0 is set to off.

If I configure TV-0 as Twinview and say auto resolution I get :

MetaMode 1 of Screen 0 has more than two active display devices.

Can someone sugguest how to fix this?

Also, the resolution of the TV is 1024x768. I want 1280x720.

Here's my xorg.conf

Section "Device"
    Identifier     "Card0"
    Driver         "nvidia"
    VendorName     "nVidia Corporation"
    BoardName      "GeForce 9500 GT"
    Option         "TwinView"
    Option         "TwinViewOrientation" "RightOf"
    Option         "UseEdidFreqs" "True"
    Option         "ConnectedMonitor" "CRT-0, CRT-1, TV"

You have to explicitly disable your other screen by clicking on it, then clicking "Configure..." and choosing "Disabled". As for the resolutions for the TV, you may not be able to get 1280x720 because TV encoders usually have a fixed set of available resolutions.

Right now I have two xorg.conf's. The below is the one I use to give me 1280x720 for 1 LCD and my HDTV. (The above was for the 2 LCD's)

The problem is that in the xorg.conf I do not no how to specify the TV to be 1280x720p on the previous config (above) I mentioned. Can of hard to explain I guess.

As you can see between the two xorg.conf's I have two diff metamodes.
