Como o dobey disse que eu precisava do opencl, mas as versões do amd-sdk do opencl não pareciam funcionar para mim (eu provavelmente estava instalando-as incorretamente). A maioria das instalações do opencl desinstala o fglrx e instala os drivers nvidia. Este é um que encontrei em um fórum que funcionou:
sudo apt-get install ocl-icd-opencl-dev
Espero que ajude alguém!
