Hello, I'm working at a research company dealing with robotics and have a nice piece of code which uses OpenGL. The problem is that one of the robots does not have a GPU which I could use. I would like to use the same piece of code on the robot without the GPU. I've been doing some research on this topic and found that the Mesa project has a way to disable hardware acceleration on purpose. I'm running on Ubuntu 10.04, compiled the latest release version from source. When I run my application it fails to load the shaders. I ran glxinfo both with GPU driver activated and without (forcing it to use Mesa). "OpenGL vendor string: Mesa Project OpenGL renderer string: Software Rasterizer" What I noticed that I'm missing is the line starting with "OpenGL shading language version string" when running with Mesa, though I also compiled glsl_compiler. Can anyone point me in a direction with this? I am aware that if it's possible it will surely throw me way back in terms of speed but I'd still like to re-implement as less code as possible. Regards, Bence
