Hi Michael, Is souinds like the Nvidia driver is trying to treat the quadroplex as a single graphics context and then do it's SLI/(distributed GL implementation) behind the scenes. Personally I think this is the wrong way to use multiple graphics cards... one should treat them as four separate graphics cards and cull to each slave camera for best performance...
Anyway, if you are going to use this system with the distributed GL implementation active and only one user side graphics context/screen then the OSG should be able to open a single window across the whole region. If it isn't then it might be that the window manager is redirecting the window to a small size, when this happens you need to enable the X11 override redirect which effectively tells the window manager that "don't touch my window settings I know what I doing". Producer .cfg and osgViewer (if you set it up manually using osg::GraphisContext::Traits::overrideRedirect to true) support override redirect. Robert.
