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

Appreciate any help
