Code:
OpenGL Renderer Gallium 0.4 on llvmpipe (LLVM 0x301)
You are using an OpenGL software renderer. I can't imagine any game is going to work with that. Perhaps your version of Xorg or Mesa is not new enough to support 3D acceleration on your GPU. You can try updating those components, if that's the case. Alternatively, you can install the AMD proprietary driver.
