Boot to text console by default

Just in-case you like the idea of disabling your Ubuntu desktop's graphical interface upon start-up and put you in terminal mode. Open terminal and edit /etc/default/grub file

sudo vim /etc/default/grub

look for this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

change it to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text"

then update your grub

sudo update-grub

then restart:

sudo reboot now

if you want to use the desktop just type: unity or startx
