Driver de placa de vídeo Intel

Olá!
Instalei o Ubuntu 11.04 em um notebook que comprei há duas semanas, e quero instalar o driver de vídeo dessa placa, pois como sempre uso projetores, o driver instalado pelo Ubuntu força que tanto o monitor do notebook quanto o projetor fiquem com a mesma resolução.

A única informação que consegui a respeito dessa placa é que seu nome é Mobile Intel HD Graphics, sem nenhuma referência numérica. Verifiquei que no site da Intel não há um driver específico para esta placa.

Como não quero ter a ingrata surpresa de instalar o driver errado e ficar sem acesso ao X, quero ter certeza de instalar o driver correto. Executando o comando lspci no terminal, o resultado é:

Então, tenho que instalar um driver para "Intel Corporation Core Processor Integrated Graphics Controller". Alguma dica de onde posso arranjar esse driver?
