+ | 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 / | ||
+ | \\ | ||
+ | Look for the line that starts with <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | # GRUB_CMDLINE_LINUX_DEFAULT=" | ||
+ | \\ | ||
+ | This will disable the initial splash screen, and enable verbose mode (i.e., showing the detailed boot procedure). | ||
+ | \\ | ||
+ | \\ | ||
+ | Then change <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | GRUB_CMDLINE_LINUX=" | ||
+ | \\ | ||
+ | Next, uncomment the line that says <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | GRUB_TERMINAL=console | ||
+ | \\ | ||
+ | The updated GRUB default configuration looks like the following: | ||
+ | \\ | ||
+ | < | ||
+ | # If you change this file, run ' | ||
+ | # / | ||
+ | # For full documentation of the options in this file, see: | ||
+ | # info -f grub -n ' | ||
+ | |||
+ | 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=" | ||
+ | GRUB_CMDLINE_LINUX=" | ||
+ | |||
+ | # 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 ...) | ||
+ | # | ||
+ | |||
+ | # 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' | ||
+ | # | ||
+ | |||
+ | # Uncomment if you don't want GRUB to pass " | ||
+ | # | ||
+ | |||
+ | # Uncomment to disable generation of recovery mode menu entries | ||
+ | # | ||
+ | |||
+ | # Uncomment to get a beep at grub start | ||
+ | # | ||
+ | </ | ||
+ | \\ | ||
+ | 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 " | ||
+ | \\ | ||
+ | \\ | ||
+ | sudo systemctl set-default multi-user.target | ||
+ | \\ | ||
+ | Now reboot and hopefully you will be at a text based login prompt. | ||
+ | \\ | ||
+ | \\ |
