Estou usando o Ubuntu 14.04. Eu sou um novato. A pasta raiz está cheia. Ao fazer atualizações antes disso, houve erros de dependência.
sudo apt-get -f install
não corrigiu isso.
Recentemente teve problemas com o Fan Error. Desligado manualmente e reiniciado o sistema. Eu verifiquei para core dumps após o resultado

Existe um arquivo massivo de 112Mb, sem nome, apenas um ponto.
Meu sistema também não está inicializando como costumava. Tudo o que normalmente era feito em segundo plano agora aparece na tela.
