O Ubuntu desacelera dramaticamente após cerca de 3 horas de uso

Eu tenho uma situação em que o Ubuntu 14.04 Desktop desacelera dramaticamente após algumas horas de uso. Eu fiz uma pergunta ( aqui ) na semana passada sobre meu mouse ponteiro ícone mudando por si só. Tenho notado nos últimos dias que essa mudança está coincidindo com uma grande desaceleração no Ubuntu - a digitação é lenta, a mudança de guias e as janelas é lenta e desajeitada, etc.

Eu tenho 16GB de RAM instalada e há cargas gratuitas quando uso watch -n 5 free -m , então não acho que seja esse o problema.

Se eu reiniciar o sistema, tudo voltará ao normal e o Ubuntu terá um bom desempenho por algumas horas até que isso aconteça novamente.

Alguém tem ideia do que poderia estar causando esse problema?

Não tenho certeza se isso é relevante, mas essa instalação foi um clone restaurado de outra máquina de especificação mais alta. Isso teria alguma coisa a ver com isso?

Edit: Acabei de perceber que, quando eu reinicio o meu sistema, os gráficos ficam muito em blocos. Isso também aconteceu nos últimos dias, mas eu não coloquei 2 + 2 juntos e relacionei com o problema acima. Para resolver o problema de gráficos em blocos no início desta semana, eu revisei o AMD Catalyst e, quando reiniciei o sistema, os gráficos estavam ok. O driver que estou usando é: fglrx-updates (proprietary) . Alguém tem alguma idéia do que está acontecendo aqui e como eu posso consertar isso?

Aqui estão minhas especificações (encurtadas porque a pergunta tem muito texto):

Obrigado por procurar. Espero que alguém possa ajudar. Vou reiniciar o sistema agora. Meu palpite é que os gráficos em blocos estarão de volta quando eu fizer isso.

Editar: sim, de fato. Gráficos de blocos de volta. Isso é muito frustrante, pois o desempenho é ótimo até que isso aconteça. Eu vou mudar o driver e depois alterá-lo novamente.

Publicando como resolvi esse problema caso alguém encontre algo semelhante no futuro.

Eu re-instalei o Ubuntu 14.04 na máquina em questão e o driver de gráficos de código aberto reconheceu imediatamente os monitores duplos. Eu tenho usado por 2 dias sem nenhum problema.

Parece que os problemas acima foram causados pelos drivers proprietários da Buggy AMD. Eu não tive nenhum deles desde que me mudei para o driver de código aberto.

E eu acho que o driver de código aberto não pegou originalmente os monitores duplos porque eu restaurei uma imagem feita de uma máquina diferente para esta. Uma instalação limpa ordenou isso.

Obrigado a todos por sua ajuda
