Just tested - current CVS checkout still hangs in Viewer::Realize() (shows black window) if I enable SLI (both AFR and SFR mode). Ltrace shows the application hanging on some ioctl call, most likely somewhere in Nvidia driver.
Does the stack trace go up to a Producer call, if so which one? I wonder if NVidia have broken some of the GLX calls related to vsync. I would very much like to drive SLI from the scene graph/Producer level, with use specifying the composting of the two graphics outputs. It wouldn't a very difficult extension to the OSG/Producer and it would allow much better scaling in performance as we could cull geometry and state at a much higher level. Anyone going to Siggraph could nag Nvidia and ATI about this... tell them to create an extensions to allow us to manage the SLI/Cross fire.
