Try nosplash debug. If you want output from upstart too, add --verbose

  • can you check to see if these options were passed to the running kernel? cat /proc/cmdline will show you what the kernel actually booted with. – Jeremy Kerr Aug 08 '11 at 05:30
  • I didn't understand where I can add --verbose, can you explain yourself better? – Mario Palumbo Mar 31 '22 at 10:56

    @MarioPalumbo this question is about changing the GRUB_CMDLINE_LINUX_DEFAULT variable in /etc/default/grub, so that's the context of the answer. – Jeremy Kerr Apr 03 '22 at 07:37

Changing

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT=""

in /etc/default/grub is correct, but you also need to run update-grub for it to take effect.

Hit Esc any time to see the text. For permanent changes, uninstall all plymouth themes, including text ones, and in /etc/grub/default uncomment the line to enable console.

    Uncomment GRUB_TERMINAL=console in /etc/grub/default works in my laptop but grub resolution decreased to 800x600. – kholis May 04 '11 at 07:49
  • You can fix resolution right there. GRUB_GFXMODE=whatever. Note that you can use only modes which your graphic card supports via VBE. You can see them in GRUB console with the command `vbeinfo' – Barafu Albino May 04 '11 at 08:18
  • vbeinfo is not found on my system [and apparently isn't in the repo], but this works: sudo hwinfo --framebuffer – Matt Oct 11 '11 at 04:42

    vbeinfo is not part of linux: it is a command that you can run from grub screen –  Jul 28 '12 at 06:54
