Hello,<br> <br>has anybody some experience with doing offscreen rendering under Linux with graphics acceleration support and give me some hints on how to get this to work?<br> <br>I'm using a vtkOpenGLRenderWindow and set OffScreenRendering to on. With that it does really not render into a window, but VTK still opens an X Window (apparently it needs its handle). So for instance when I try to start a VTK based app remotely via SSH I get the following error message:<br>

<br>When I build VTK with MESA enabled it works, but the performance without accelaration is unacceptable.<br> <br>Thanks,<br>Mark
