I've had similar issues with VirtulGL and VTK in the past. The "Shader object was not initialized, cannot attach it." error is often the result of some sort of required OpenGL version support for a specific call is lacking. A few questions:
- Are you able to run on the actual machine without Virtual GL? - What does the output of glxinfo running in the x2go+VirtualGL environment look like? - Chuck On Mon, Apr 11, 2016 at 9:56 AM, Ken Martin <ken.mar...@kitware.com> wrote: > As I understand it VirtualGL should transparently forward OpenGL/GLX/etc > calls from the server to the client so that the client GPU is used.
