Ola pessoal,
comprei a minha maquina em abril. Naquela época, tentei instalar o ubuntu nativamente sem sucesso.
Acabei optando pelo wubi, no qual consigo roda-lo sem problemas e com excelente desempenho, assim como a instalacao do vista q possuo.
Quando instalo o ubuntu (tentei tambem com o fedora e o slackware), o desempenho do sistema é pífio, impossível e se utilizar.
O hd faz muito barulho, e é como se o kernel subutilizasse o disco. Tentei recompilar o kernel, mas n obtive exito.
Às vésperas do lancamento do intrepid, tentei instalar a versao RC do mesmo, e o problema persiste.
Nao consigo imaginar qual é o problema, ja que minha instalacao do vista e a instalacao do wubi rodam sem problemas.
QQ sugestao é mto bem vinda, ha tempos tento instalar o ubuntu nativo sem sucesso.
Segue abaixo informacoes do meu hardware:
