That wouldn't help, that option is for overriding the monitor detection. However, he said that the image appears on both monitors in windowed mode, so the second screen was obviously detected right. I have noticed another issue - "AddARGBGLXVisuals" is on. This is usually needed by things like Beryl or Compiz. Jean-Sebastien, do you have, by chance, also Composite extension enabled? That one is known to interfere with OpenGL rendering, I would turn it off. Also, you may want to explicitly specify the resolution and/or turn off Xinerama extensions in your window manager. I presume that you want to have the window maximized *on both* screens, not only on the current one. My guess is that osgViewer detects the full resolution of the two screens, however the window manager forces the window to be maximized only on one display and OSG is not aware of it (therefore the "cut" object centered on the screen boundary) . That is usually desired (e.g. maximizing Firefox across two screens would be a pain to work with), however in this case you need to turn it off. You can turn off Xinerama globally in the xorg.conf using an option: Option "Xinerama" "false" Alternatively, you can turn it off in KDE in control panel under "Window Behavior" or you can force the window size to be always full screen using the window specific settings, e.g. 2560*1024 if you have 2x 1280x1024 screens.
