VirtualGL is designed to be used with a dedicated 3D X server, i.e. with a GPU-attached X server that is not logged in or otherwise doing anything not related to VirtualGL. Are you saying that the 3D X server is logged in and this issue occurs when the screen saver activates on it? If so, then that is not an issue we can solve.
