Estou enfrentando exatamente o mesmo problema mencionado no link, mas no Ubuntu 14.04 64 Bit.
Enfrentando o problema:
- O ponteiro do mouse congela por cerca de 300 ms sempre que o ícone do cursor muda:
- Ao passar o mouse do campo de texto para o ponteiro do mouse.
- Ao cruzar a borda da janela, o cursor muda para redimensionar o cursor para voltar ao ponteiro do mouse.
Está acontecendo o tempo todo e em todos os aplicativos (Excessivamente no Chromium, Firefox)
Há um outro problema no contexto do clique direito que é muito lento, mas não sei se está relacionado ou não.
Coisas que tentei, mas sem sucesso:
- Alterando o ambiente da área de trabalho para Unity / canela / gnome-flash-back
- Alterando meus drivers gráficos para Xorg / AMD proprietário
- Diminuir / aumentar a aceleração e a sensibilidade do touchpad / ponteiro do mouse.
Configuração do sistema:
Dell N4110
Atualização 1
Eu instalei o indicador-multiload e observei iowait alto, mesmo com% de CPU próximo de 7-8. Usando o iotop, observei 2 Processos específicos, como o kworker e o jdb, estão causando alta operação io. Não tenho ideia do que esses processos estão fazendo.
Atualização 2
Eu procurei em / var / log / syslog e o conteúdo é o seguinte:

Eu executei os dados SMART e fiz o autoteste sem falhas. Então, meu disco rígido está funcionando bem?
Há algum problema com o cabo SATA? Como posso confirmar sem usar outro hardware. Por favor, sugira o que mais eu posso tentar ou uma solução.
