Bem-vindo ao mundo de nenhuma API do kernel estável.
Enfim, parece que será corrigido no Catalyst 12.5, ou se você precisar de uma solução alternativa: link
Atualizei recentemente meu kernel do Ubuntu 12.04 para o 3.4.3-generic e agora meus drivers ATI / AMD não serão instalados corretamente. O AMD Catalyst Control Center está lá, e eu posso abri-lo bem, mas ele só mostra gráficos 2D como sendo habilitados. Minha placa de vídeo é a Radeon HD 7770, e estava funcionando perfeitamente no meu kernel antigo (2.5.xx). Eu recebo a seguinte saída ao tentar instalar os drivers mais recentes da AMD (o erro é um pouco mais do que meio caminho):

Basicamente, parece que o instalador está falhando ao tentar construir para o kernel 3.4.3 ... há algo que eu possa fazer sobre isso, ou eu tenho que esperar que a AMD libere drivers atualizados?
