Eu atualizei meu Kubuntu para o 16.04. Desde então, não consigo encerrar minha sessão imediatamente. Quando escolho a opção do menu, tudo corre como esperado inicialmente. No entanto, cerca de 5 segundos após o HP Probook 4340s ser desligado, ele começa novamente como se o botão liga / desliga fosse pressionado novamente (e não era).
A instalação laptop-mode-tools não ajudou, nem as modificações das configurações do grub (" acpi=noirq " / " acpi=force " e " apm=power_off "). A configuração Wake-on-LAN no BIOS também está desativada.
Ao estudar o log journalctl dos procedimentos de desligamento e início, também não mostrou nada suspeito.
Eu não acho que o problema esteja relacionado ao hardware, já que não ocorreu em versões anteriores do (K) Ubuntu.
Onde poderia estar o problema? O que mais devo verificar?
