Eu instalei recentemente o Ubuntu 18.04 Desktop no meu PC (que anteriormente tinha o Windows 10). No entanto, notei que leva alguns minutos para iniciar, às vezes 4-5 minutos. A partir da experiência passada com o Ubuntu eu sei que isso é demais e que ele pode arrancar em segundos. Eu executei alguns comandos para descobrir o que está demorando, mas não consigo descobrir o que fazer com a informação. Estou colando a saída aqui:
