Meu laptop congela imediatamente após a suspensão (ele não fica no modo de suspensão, ele congela um pouco antes do tempo necessário. A tela fica em branco, mas permanece brilhante).
Isso só acontece quando a conexão sem fio é ativada, se eu desabilitá-lo, a suspensão está certa. Não há problema com a conexão com fio.
Após mexer e solucionar problemas, eu reinstalei o sistema operacional novamente e descobri que a suspensão funcionava bem, até que eu instalei algumas atualizações recomendadas, porque logo em seguida o laptop suspendeu o congelamento novamente. Eu pesquisei /var/log/apt/history.log e tenho certeza de que o problema deve ser uma (ou algumas) dessas atualizações:
