Eu uso o Ubuntu 16.04 em um computador com um processador AMD dual-core montado há mais de oito anos.
Passaram-se cerca de duas semanas atrás, quando inicio o computador, é apreciado que ele esteja continuamente acessando o disco rígido e tudo está muito lento. Alguns dias se comporta assim durante toda a sessão de trabalho, outros depois de um certo tempo, é normalizado. Sem qualquer aplicativo aberto, o Monitor do sistema marca uma utilização de 50 a 60% da CPU. Com o comando top você pode ver que o dconf-service está continuamente escrevendo e o Xorg e o Compiz consomem 10-15% do uso da CPU. Hoje iniciei o computador às doze e até as três e meia não regularizou seu comportamento. Durante esse tempo, gerou um log de mais de 35 MiB. Eu anexei o começo e o fim do syslog. Qualquer ajuda é bem vinda. Obrigado. Google traduzido.
