 ====== Force Boot to Command Line ====== ====== Force Boot to Command Line ======
 +<color darkorange>May 2017</color>
 +\\ 
 +\\ 
 +
 +----
 +
 +Having installed a netinstall version of Lubuntu (the smallest ISO I could get) on a Sony Vaio netbook, I had no option during the install to not include the bundled shell. So I wanted to force Linux to boot only to the command line, here is what I did:
 +
 +----
 +\\ 
 +Open the GRUB config file with a text editor (Make a backup first).
 +\\ 
 +\\ 
 +    sudo vi /etc/default/grub 
 +\\ 
 +Look for the line that starts with <color #ed1c24>GRUB_CMDLINE_LINUX_DEFAULT</color> and comment out that line by placing a hash <color #ed1c24>#</color> symbol in front of it. 
 +\\ 
 +\\ 
 +    # GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
 +\\ 
 +This will disable the initial splash screen, and enable verbose mode (i.e., showing the detailed boot procedure).
 +\\
 +\\ 
 +Then change <color #ed1c24>GRUB_CMDLINE_LINUX=""</color> to:
 +\\ 
 +\\ 
 +    GRUB_CMDLINE_LINUX="text"
 +\\ 
 +Next, uncomment the line that says <color #ed1c24>"#GRUB_TERMINAL=console</color>.
 +\\ 
 +\\ 
 +    GRUB_TERMINAL=console
 +\\ 
 +The updated GRUB default configuration looks like the following:
 +\\ 
 +<file>
 +# If you change this file, run 'update-grub' afterwards to update
 +# /boot/grub/grub.cfg.
 +# For full documentation of the options in this file, see:
 +#   info -f grub -n 'Simple configuration'
 +
 +GRUB_DEFAULT=0
 +GRUB_HIDDEN_TIMEOUT=0
 +GRUB_HIDDEN_TIMEOUT_QUIET=true
 +GRUB_TIMEOUT=10
 +GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
 +# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
 +GRUB_CMDLINE_LINUX="text"
 +
 +# Uncomment to enable BadRAM filtering, modify to suit your needs
 +# This works with Linux (no patch required) and with any kernel that obtains
 +# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
 +#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
 +
 +# Uncomment to disable graphical terminal (grub-pc only)
 +GRUB_TERMINAL=console
 +
 +# The resolution used on graphical terminal
 +# note that you can use only modes which your graphic card supports via VBE
 +# you can see them in real GRUB with the command `vbeinfo'
 +#GRUB_GFXMODE=640x480
 +
 +# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
 +#GRUB_DISABLE_LINUX_UUID=true
 +
 +# Uncomment to disable generation of recovery mode menu entries
 +#GRUB_DISABLE_RECOVERY="true"
 +
 +# Uncomment to get a beep at grub start
 +#GRUB_INIT_TUNE="480 440 1"
 +</file>
 +\\ 
 +Now use update-grub command to re-generate a GRUB2 config file in /boot based on these changes.
 +\\ 
 +\\ 
 +    sudo update-grub 
 +\\ 
 +For systemd-enabled desktop only: If your desktop uses systemd (e.g., for Debian 8 or later or Ubuntu 15.04 or later), there is one additional step needed. That is to change the default target from "graphical" target to "multi-user" target. Skip this step if your desktop does not use systemd.
 +\\ 
 +\\ 
 +    sudo systemctl set-default multi-user.target 
 +\\ 
 +Now reboot and hopefully you will be at a text based login prompt.
