1I am not sure, but try it. On the grub options remove quiet.– karthick87May 2, 2011 at 2:20

2Did you run "sudo update-grub" after making changes to /etc/default/grub ?– karthick87May 2, 2011 at 2:31

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, 2022 at 10:56 -
1@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, 2022 at 7:37
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.

GRUB_TERMINAL=console
in /etc/grub/default works in my laptop but grub resolution decreased to 800x600.– kholisMay 4, 2011 at 7:49 -
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' 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

2vbeinfo is not part of linux: it is a command that you can run from grub screen– user79811Jul 28, 2012 at 6:54
