Note the warning about the OpenGL rendering context. That is the problem here. It appears you are overriding the value of VGL_DISPLAY. Why are you doing this? VGL_DISPLAY should always be set to the display where you want the 3D rendering to occur, which in this case is the X display where the GTX295 is connected. If it is connected to :0.0, then unset VGL_DISPLAY, because :0.0 is the default value of that variable.
The User's Guide explains this in great detail.
