Plymouth Error - erro de inicialização e desligamento

Question

Eu estraguei minhas configurações plymouth no Ubuntu 16.04 ao tentar instalar novos temas. E agora meu sistema não vai desligar e congela. No boot, o systemd gera muitas mensagens de erro. Mas o sistema inicializa e funciona corretamente (exceto desligar).

Alguém pode me ajudar a reiniciar o plymouth?

    

Answer 1

Abra um terminal e execute os seguintes comandos, um de cada vez:

1. sudo gedit /etc/default/grub
2. Encontre a linha: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
3. Altere para: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
4. Salve e feche o arquivo.
5. Finalmente, no terminal: sudo update-grub

Espero que ajude você
