Como conecto o Ubuntu à TV LED Sony Bravia via HDMI?

Question

Meu laptop conecta a 46 "Sony Bravia LED TV usando o cabo HDMI no Windows sem qualquer problema. No entanto, ele simplesmente não funciona com o Ubuntu 12.04. Ele sempre diz sem sinal.

O problema persiste um pouco após a atualização para o 13.04. Bravia detecta meu laptop como uma conexão agora, mas não consigo exibir nada.

Quais drivers / aplicativos devo instalar para conectar via HDMI?
