Logout aleatório e repentino da minha sessão de usuário

Eu tenho um problema com o ubuntu 14.10 e 15.04. Saí da minha sessão de usuário aleatoriamente e de repente.

Aqui estão algumas informações de log:

kern.log

Alguma idéia para consertar isso?

Digite Ctrl-Alt-F1 e faça login em uma sessão do terminal. sudo grep metacity /var/spool/log/*

@ Aliot Qualquer erro nos logs do Xorg também pode ajudar na solução de problemas. sudo grep EE /var/log/Xorg.0.log

— cargo

você tentou dpkg-reconfigure metacity? (nunca feito mysef, mas se isso falhar, talvez o problema é metacity ou servidor X configuração)

— feligiotti

isso é exatamente como o que meu amigo enfrentou. e ele percebe que sua sessão sempre é desconectada repentinamente se ele executa o Chrome. você experimentou isso ao executar um programa específico? isso é realmente um bug. no seu caso, parece 'metacidade'. tente usar outro programa gerenciador de janelas.

— adadion

podemos obter algumas informações específicas de hardware, abra um terminal e digite lspci e, em seguida, poste a saída, por favor. Você também instalou algum tema ou modificou a GUI?

Este é um bug não resolvido, mas relativamente raro, se você estiver usando a sessão gnome-flashback. Em parte porque a maioria está usando a interface do usuário padrão. Veja mais detalhes e inscreva-se para verificar se o problema foi resolvido aqui: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1455916

Correção temporária - não use a sessão gnome-flashback.
