Pelo visto vc já deu uma alterada no seu sistema. Andou instalando kernel diferente do que vem no sistema?
Sempre que for tirar uma dúvida aqui no fórum, poste a sua versão do Ubuntu, e toda a configuração do seu hardware com o comando lspci, essas coisas ajudam muito a análise aqui (e também não dá para enxergar daqui, rsrs .
E o lspci ? Meio que não dá para enxergar a sua placa de vídeo daqui... rsrs
Vc está conseguindo efeitos 3D no seu desktop? Está lento? Consegue rodar jogos nele? Entre com o comando lsmod também.
