Eu tenho uma combinação de erros relatados em outro lugar, como este problema de logout e este problema de inicialização . Só que no meu caso isso acontece duas vezes na inicialização. Primeira vez após o daemon ter iniciado, o segundo antes ou na tela de logon. Não é o serviço thermald , pois parar não altera o comportamento de logout. Além disso, o computador vai dormir toda vez que eu alternar para um terminal, ou seja, pressione Ctrl + Alt + F1. Nunca aconteceu em 14 de abril, porém, presenciei algo semelhante em uma instalação de teste de arco.
O hardware é bem antigo. É um Cebop Hel500 de 2005. Isso é baseado em um Fujitsu Siemens Amilo, então basicamente o hardware é todo Intel.
Eu já tentei alterar o gerenciador de exibição (para slim ) e removi light-lock ... em vão.
Infelizmente, esse comportamento processa o uso de 16.04. muito desconfortável. Alguma idéia do que causa isso e - ainda mais importante - como pará-lo?
.... why-o-why eu atualizei ... nunca mude um sistema em execução!

O boot.log não mostra nenhuma informação sobre suspensão ou suspensão.
Um ponto importante é que o sono também ocorre se eu iniciar o computador com um stick ao vivo do debian jessie. Então eu acho que é um problema mais fundamental não exclusivamente, mas incluindo o Ubuntu.
Ainda mais informações: Eu pensei que poderia ser um problema no kernel, enquanto o Lubuntu tem o 4.4, o debian live (lxde) tem 3.16. Tal tem o Hidrogênio Bunsenlabs, mas lá não vejo a suspensão.
Errado: Bunsenlabs tem o problema de suspensão, mas não no login. Uma instalação de teste mostra isso no logout e depois de mudar para tty1,2,3, etc, ou seja, Crtl + Alt + F1, etc.
