Eu passei por um programa de excluir os drivers fglrx instalados instalados pelo Ubuntu, seguindo estas etapas link para instalar os drivers AMD atualizados.
Isso faz as coisas acontecerem por mim.
Eu tenho informações conflitantes sendo dadas a mim, por um lado, o painel "Drivers Adicionais" menciona que o driver proprietário ATI / AMD está instalado, mas o < em> painel "Detalhes" informa-me que o "Gallium 0.4 on llvmpipe (LLVM 0x300) "
está em uso.
Estou usando o Ubuntu 12.04 beta
Como posso ter certeza de que o driver ATI é usado?

Pesquise a string "LoadModule" em /var/log/Xorg.0.log. Você terá que repetir a pesquisa várias vezes até chegar ao que mostra seu driver de vídeo. O que quer que seja exibido neste arquivo é o que está sendo usado.
