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

Hi Alan,
what vendor string do you have, when you type in glxinfo? (You might have to install it first) What GPU do you have? What GPU drivers do you use?

you could also use [print( -> [gemwin] once the window is created

right, these are better questions than my laconic comment.
geometry shaders need fairly recent hardware, and are (to my knowledge) only supported by proprietary drivers (on linux: nvidia for sure; dunno about ati)

ah nice :)
@Alan:
I see a: "Extensions: GL_EXT_geometry_shader4" in my List. This is probably what you need.
--snip-- GEM information
OpenGL info Vendor: NVIDIA Corporation Renderer: GeForce 9800 GT/PCI/SSE2 Version: 3.3.0 --snap--
And it should look like this, if you own a nvidia-GPU. Otherwise you will have to install the proprietary drivers.

Hi all,
Thanks for the comments,
here is my list:
GEM information
OpenGL info Vendor: NVIDIA Corporation Renderer: GeForce 7025 / nForce 630a/PCI/SSE2/3DNOW! Version: 2.1.2 NVIDIA 260.19.21
hmmm I dont see GL_EXT_geometry_shader4 on the list so must be to do with my crud integrated graphics
no worries though, as per IOhannes suggestion I currently trying to download new-graphics-card now from the Ubuntu software centre...
...if only! Thanks again
