HI List,
I am trying to learn the pixel shaders/geometry aspect of Gem on Ubuntu, but in trying to load the [glsl_geometry] help patch I get the following error message on rendering: error: [glsl_geometry]: need OpenGL-2.1 (or at least the geometry-shader ARB-extension) to run GLSL ... you might be able to track this down from the Find menu. I can find any way to update from synaptic -is there a way I can get this updated/working? Appreciate any help Alan
