Estou usando um laptop hp com processador de 4 GB e processador AMD de 2,2 GHz e o Ununtu 16.04 instalado nele. Antes eu estava usando o windows 7. Eu formatei todo o disco rígido e instalei o Ubuntu.
Ele inicializa algumas vezes bem devagar. Leva 5-10 minutos (não todo o tempo algum tempo carrega muito rápido menos então um min). Eu não tenho muitos aplicativos instalados no int e verifiquei aplicativos de inicialização também não há nada.
aqui está o log do sistema de boot:

Eu também tive esse problema e resolvi o meu agora. Aparentemente, no / etc / fstab, havia uma referência para uma partição swap inexistente no meu disco rígido secundário, porque eu já o formatei hoje. E foi aí que começou a demorar 2-3 minutos para arrancar. Ele estava inicializando em 10 segundos antes disso. Como mencionado aqui, fórum do archbang
Comentei essa parte no arquivo fstab sudo gedit /etc/fstab e foi corrigido.
