They should work fine, so I'm not sure what could be happening there. The whole idea behind VirtualGL is that it intercepts mainly just the functions that touch the X display, such as glXCreateContext(), etc. Once the context has been effectively re-routed into a Pbuffer on the 3D X server, then everything else that takes place at the OpenGL level should seamlessly pass through to that. The key word there, however, is "should". I am able to run simple GLSL examples, such as the ones in mesa-demos, in VirtualGL with no issues. Sorry that that isn't more helpful. It's just impossible to say more without knowing what the app is trying to do. ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
