Ubuntu 14 server edition, how to boot into single-user mode?
I got the answer. At this line:
linux /vmlinuz-3.13.0-32-generic root=/dev/mapper/ubuntu-vg-root ro
append single
and it becomes to
linux /vmlinuz-3.13.0-32-generic root=/dev/mapper/ubuntu-vg-root ro single
Then press Ctrl + x. You will goes into single user mode.
To make this permanent, you need to edit /etc/default/grub
and change this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="text"
The details may vary depending on your system. The important bit is setting GRUB_CMDLINE_LINUX_DEFAULT
to text
. Once you have done this, run sudo update-grub
and next time you restart you will boot into text mode.
