Thanks, Robert, This confuses me more:-). To my knowledge, on my machine, X server has created a large screen (2422x1050 by overlapping two 1400x1050 display area with 378pixels blending region). I think, might be incorrect, that overlapping is hidden by video driver and X server so that applications should only see a 2422x1050 screen size. I feel this correct because I can startup osgViewer in window mode and manually resize the window to span the entire 2422x1050 display area.
But if I start osgViewer in full screen mode, it only spans to one 1400x1050 area. I am hoping to see a solution to enable osgViewer to start up to span the entire 2422x1050 display area in full screen mode. For now I can just manually drag osgViewer window to span to the entire screen.
