Ubuntu 17.10 O Acer Aspire E5 leva 10 minutos para desligar

Question

Estou tendo problemas com minha nova instalação do Ubuntu 17.10. Leva 9 minutos e meio para desligar. Anteriormente, eu pensei que era a troca que não funcionou, então eu reinstalei usando a seguinte configuração de partição:

• linux-swap 512 MB
• ext4 118 GB

Meu computador:

• CPU Acer Aspire E 15 E5-575G-55F8: Intel Core i5-7200U
• GPU: Nvidia GeForce 940MX
• Ram: 8 GB
• HD: SSD de 128 GB
