Eu já postei umperguntaem que solsTiCe me mostrou como configurar um swap em uma partição GPT. Funcionou por um tempo, mas agora estou tendo problemas novamente. A troca não foi detectada novamente. Segui exatamente o mesmo conselho, mas não funciona desta vez. Após a reinicialização, aparece uma mensagem cryptswap perguntando se desejo pular a montagem, etc. Após o login, freenão mostra nenhuma troca, sudo fdisk -lmostra a seguinte saída:

blkidtem exatamente a mesma saída da pergunta anterior, e o mesmo acontece com sudo gdisk /dev/sda.
A saída de /etc/fstab/é:

Encontrei a respostaaqui:
Alterado /etc/crypttabpara incluir:
cryptswap /dev/sda9 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256
e /etc/fstabincluir:
cryptswap /dev/sda9 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256
