How to make natty boot in verbose mode. Changing option GRUB_CMDLINE_LINUX_DEFAULT="splash quiet to GRUB_CMDLINE_LINUX_DEFAULT="" in /etc/default/grub doesn't effect in natty.

    I am not sure, but try it. On the grub options remove quiet.

    Did you run "sudo update-grub" after making changes to /etc/default/grub ?

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. Aug 8, 2011 at 5:30
  • I didn't understand where I can add --verbose, can you explain yourself better? Mar 31 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. Apr 3 at 7:37





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.

  • 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' May 4, 2011 at 8:18
  • vbeinfo is not found on my system [and apparently isn't in the repo], but this works: sudo hwinfo --framebuffer

    vbeinfo is not part of linux: it is a command that you can run from grub screen
