Ubuntu 16.04 Inicialização lenta

Question

Eu tenho 16.04 em um antigo laptop Acer Aspire i5 430m. É lento para arrancar, eu fiz uma instalação completamente limpa e ainda é bastante lento. Lendo algumas outras perguntas sobre isso eu fiz um dmesg logo após o boot e procurei grandes lacunas no tempo, não é isso:

systemd-analyze me dá isso:

Startup finished in 13.814s (kernel) + 2min 2.754s (userspace) = 2min 16.568s

systemd-analyze culpa me dá isso:

Não sei o que fazer. É atualizado e uma vez que vai indo parece ser tudo OK e não lento. Alguém pode sugerir algo para acelerar?
