Ubuntu 16.04 - sudo pm-hibernate não funciona

Question

Quando eu faço sudo pm-hibernate , a tela desliga por um segundo e depois volta. Eu verifiquei o log usando head /var/log/pm-suspend.log e aqui está o resultado:

Initial commandline parameters: 
Wed Dec 21 12:11:34 IST 2016: Running hooks for hibernate.

O GParted mostra que eu tenho 7,2 GB de troca de Linux, que é quase o dobro da minha memória RAM.

Como eu procuro agora?

EDITAR: Eu abri pm-suspend.log e rolei para o final do arquivo. Aqui está o resultado:

Answer 1

Faça isso:

sudo apt-get update
sudo apt-get upgrade

Em seguida, tente sudo pm-hibernate Isso levará pelo menos um a dois minutos para o modo de hibernação
