Ubuntu 10.04 no Dell XPS 1330 e muitos problemas

Question

Eu instalei recentemente o Ubuntu 10.04 ao lado do meu Windows XP no meu laptop: Dell XPS 1330

Agora estou enfrentando alguns problemas com meu novo sistema operacional:

1. O driver da minha placa de rede sem fio não é reconhecido, embora eu tenha instalado o driver recomendado que estava na seção do Driver de Hardware do Ubuntu.

2. Quando conecto meu laptop à minha TV usando a porta HDMI, a tela fica boa, mas não há som!

3. Quando, por qualquer motivo, meu cabo de rede é desconectado, todo o serviço de rede fica inativo e preciso reiniciar o sistema.

Agradecemos antecipadamente por sua ajuda.
