NVidia twinview / xinerama issue

Hi there all, excuse the potential newb post...I had a search around the forums and could not find an answer to my issue....

I have a NVidia carding doing their twinview flavour of xinerama. When I go full screen with the _13 (or _9 before that) client it insists on giving me a single monitor set to 2880 by 900, which is my total desktop space across both monitors rather than the 1440x900 it should be using. I tried editing the settings.xml file and even setting it read only bu it still always picks up and uses the 2880 width.

Does anyone know a fix for this?

thanks

This is a problem native to TwinView, and shows itself for all applications. The only other way is to split into two seperate displays... but then you lose moving one app from one screen to another.

thanks for the reply. I realise this is a twinview issue, what I'm hoping is that there is a way that i can set a resolution manually.

I don't know why you would need fullscreen, but if you feel you need, you might want to run SL in a nested rootwindow (a programm that is XServer and XClient at the same time) like e.g.

gdmflexiserver --xnest

(comes with gnome)
also accessible @ gnome menu:

1. Applications
   1. System Tools
      1. New Login in a Nested Window
         
      
      
   
   

If you now resize the nested XServer to only cover one of your physical screens you can start SL within it and set it to fullscreen.

Seems like there's no hardware 3D acceleration in nested XServers, so my approach probably doesn't work, sorry.
