Hi Harry, VNC/GLX support is likely the problem rather than a specific problem with OSG. You say that glxgears works fine, and that running osgviewer glsl_simple.osg reports errors but in the end renders shapes. To me this suggests that the OSG has been able to create a graphics context, but the GL driver being just used simply doesn't support all the extensions.
Does osgviewer glider.osg work OK? Robert. On Thu, Aug 26, 2010 at 10:42 PM, Harry Johnson <[email protected]> wrote: > Hi, > > I am new to OSG so be gentle.
