Nvidia multimonitor

[Vadi]

I use Xubuntu Feisty with 1.0-9755 drivers. The card is Geforce 7600GS I have a problem with full screen gaming. I use two displays (CRT and DFP) and while the desktop is fine, full screen games try to use both screens. The image is centered so each monitor should show half of the image but the DFP actually doesn't display anything. Quitting to desktop shows some weird panning bug but it goes away easily.
Can I do something about this?

How can I add multiple monitor sections in xorg.conf? I want to add a custom resolution for the CRT.


Thanks!

I presume you are using Xinerama. For games, maybe you should try Twinview.

Thanks SPM! :)
I do use Twinview I guess. Here is my xorg.conf:

edit:
I got it to work now. I never tried to reboot and that seems to be a problem. Also 'I use the xorg.conf preview in nvidia-settings.

The only problem are the games. I guess I have to chose the right meta mode ingame. However that's impossible without seeing the whole screen.
Is this a game bug or can I do something via the driver?

I don't know if this is the issue, but according to the nVidia documentation, hardware that can only be used on one display at a time (e.g.: video overlays, hardware accelerated RGB overlays), cannot consequently be used at all when in TwinView. Also I am not sure if the game will necessarily go through X to do full screen rendering.

edit:
When I take a screen shot, everything looks fine though (in the image file).
In windows it works.

I already configured my xorg.conf using this readme (Yesterday I reinstalled Linux on a different PC because I didn't know the xorg.conf had to have a last empty line, otherwise it was invalid. :runaway: 1440x900 wasn't available either. Now that one works too.).
I emailed Nvidia support and the response was to use metamodes where one display is off before playing full screen games.
