Ubuntu 11.04 desconecta aleatoriamente no meio do uso [closed]

Question

Eu posso ver que existe uma pergunta já. Como meu problema é não é exatamente o mesmo, mas bastante semelhante, tanto quanto eu entendo, eu estou perguntando isso também.

Basicamente no meio do meu uso, ou seja, navegando na net ou executando um aplicativo aleatório. O Ubuntu me envia para a janela de login e eu tenho que fazer o login novamente. Eu não sei se o GDM é reiniciado ou algo mais. Este é um problema que eu enfrento mesmo na versão estável do Ubuntu.

Existe algum bug que eu não conheço ?? Como posso depurar isso?

Aqui está minha saída do arquivo ~/.xsession_errors .

Recentemente, recebi uma atualização para as sessões do gnome. Espero que resolva o problema, no entanto só posso ter certeza depois de testar por alguns dias ... Vai atualizar a situação.

UPDATE: Não há progresso, tenho a atualização, mas o problema persiste. Mas parece ser muito menos frequente do que costumava ser. Eu estou seguindo esta questão, como algumas pessoas me sugeriram para reinstalar, mas agora eu me deparo com Unity congela após a mudança de configuração do compiz

    

Answer 1

Este é um bug .

    

Answer 2

Isso pode ser uma falha no driver de vídeo. Qual é a sua placa de vídeo? Você usa driver proprietário? Se sim, tente outra versão ou tente removê-la completamente. Ou, infelizmente, pode haver muitas outras peças de hardware. O servidor X é um colosso nas pernas de barro e mais vulnerável a falhas de hardware. Verifique sua memória (memtest86), HDD (fsck, smart), temperaturas (lm-sensors). Tente desligar todo o hardware e software desnecessários. Eu tinha visto o servidor X travar quando o EiskalDC ++ tentou indexar um arquivo de 100Gb, por exemplo. Você já leu logs, dmesg? Alguma coisa suspeita? P.S. Desligue o compiz. Está ativado por padrão no Ubuntu.

    

Answer 3

Você está usando o Unity ou o GNOME? Experimente o outro. Se isso não funcionar, sugiro Experimente o Xubuntu (para ver se é o GNOME). Se tudo isso falhar, faça backup de sua partição ou pasta, e copie / var / cache / apt para outra pasta e reinstale-a. Use os pacotes do cache para reinstalar seus aplicativos.

    

Answer 4

Tente (em um terminal, sem SUDO):

unity --reset

e depois não toque novamente no CCSM (Configurações do Compiz). Não sei se isso realmente ajuda no seu caso, mas estou na mesma situação e testando se as falhas ainda ocorrem.
