Estou usando o Ubuntu há algum tempo e atualizei para a versão mais recente há alguns meses. Eu notei, então e agora, que o 12.04 parece rodar muito mais devagar no meu computador e, ocasionalmente, trava sempre que ele está baixando arquivos, seja do Dropbox, do Chromium, do Update Manager, etc.
Eu tentei executar o comando top
também, mas com base na saída, que colei abaixo, ele não deve estar congelando. Alguma idéia de como eu posso mudar isso, ou devo enviar um ticket de bug?
