Per visudo, per abilitare sudo senza password:

sudo VISUAL=vi visudo

# decommentare `%sudo ALL=NOPASSWD: ALL' line in `visudo`, and move to end.

Per 8.04/8.10/9.04, /boot/grub/menu.lst va modificato così:

sudo vi /boot/grub/menu.lst

# Aggiungere:
  serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
  terminal --timeout=3 serial console

# Aggiungere in menu.lst alla riga del kernel (sostituendo `quiet splash'):
  console=tty0 console=ttyS0,115200n8

Per 9.10, /boot/grub/menu.lst va modificato così:

sudo vi /etc/default/grub

# Aggiungere/modificare queste voci:
    GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8"
    GRUB_TERMINAL="serial"
    GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1"

sudo update-grub
