Eu vejo várias perguntas anteriores sobre problemas com laptops perdendo serviços de gerenciador de rede após retornar de estados de suspensão / hibernação. Estou tendo esse problema com bastante frequência com o Ubuntu 17.x em um Lenovo Z710.
As perguntas anteriores tinham uma resolução de script do systemctl do Network Manager, mas antes de considerar isso, gostaria de verificar se o problema do meu laptop está ocorrendo com um estado de suspensão / hibernação ou algo mais. Eu extraí os eventos de log do sistema para tentar localizar os eventos relacionados à suspensão / hibernação, mas não consigo identificar o evento.
Eu estou anexando o log extraído se alguém tiver o conhecimento necessário para identificar um problema ajudado pelo script de reinicializações do gerenciador de rede. Parece uma solução duvidosa, mas preciso de algo para me ajudar a acessar o sistema remotamente.
Obrigado se você puder ajudar.
