I'm just wondering why your output says 'boot_success=0', surely that should be
a '1'.

You could also run 'cat /proc/cmdline' to see what has actually been passed to
the running kernel.

Final point is that your kernel version (5.3.7) seems to be somewhat older than
the other one mentioned above (5.5.8 - although I'm on 5.5.11 at this very
moment). Perhaps doing an update and then a reboot may help.

As far as I know this resume option is only used when resuming: it
doesn't affect normal boot. The UUID should be the one of the swap
partition.

I think the stanza will be instead in /boot/loader/entries/* except
perhaps if the machine is multi-boot and then grub2-mkconfig generates
legacy menu entries in the /etc/grub.d/30_os-prober section

I don't think this is needed.

Are you really trying to resume instead of booting from the installed
system?

As Francis already said, you are still booting using legacy grub, so
your grub.cfg will be in /boot/grub2/ as grub.cfg.  Maybe you could
show the boot stanza from that file here?

If you want to boot from the grub.cfg you should comment out the above
GRUB_CMDLINE_LINUX and replace it with the one from the most recent
entry in the /boot/grub2/grub.cfg file.  Then rerun the 
grub2-mkconfig -o grub.cfg file in the /boot/grub2 directory.

I think this is because of the resume from hibernate.

[Francis . Montagnac]

Hi

With this, grub2-mkconfig will generate in /boot/grub2/grub.cfg (your
previous trace shows that your machine is not using EFI):

### BEGIN /etc/grub.d/10_linux ###
...
# The blscfg command parses the BootLoaderSpec files stored in
# /boot/loader/entries and populates the boot menu. Please refer to
# the Boot Loader Specification documentation for the files format:
# https://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/.

set default_kernelopts="root=UUID=XXX YYY"

insmod blscfg
blscfg
### END /etc/grub.d/10_linux ###

Where XXX is the UUID of the rppt filesystem, and YYY is deduced from
GRUB_CMDLINE_LINUX present in /etc/default/grub
Ex: 

  set default_kernelopts="root=UUID=509e4d95-a5f5-40e6-94e9-8bbff77f32cd 
resume=/dev/disk/by-uuid/d16bbc09-698b-4e97-9aa0-c37328b36422 "

then, in my case, the /boot/loader/entries/* files only use the
default_kernelopts

Ex:

  title Fedora (5.5.6-201.fc31.x86_64) 31 (Thirty One)
  version 5.5.6-201.fc31.x86_64
  linux /boot/vmlinuz-5.5.6-201.fc31.x86_64
  initrd /boot/initramfs-5.5.6-201.fc31.x86_64.img
  options $kernelopts
  grub_users $grub_users
  grub_arg --unrestricted
  grub_class kernel


Check if those files differ from mine, ex: set options differently.

Have you checked /boot/grub2/device.map ?

I think you just want to edit /etc/default/grub and remove them from
the default kernel arguments.  Maybe copy the line and comment the old
one before changing.  You could add a timeout so the menu is visible
for a short time,
GRUB_TIMEOUT=10

Then go to where the grub cfg file is,
/boot/grub2 for non uefi
/boot/efi/EFI/fedora for uefi
and run
grub2-mkconfig -o grub.cfg



Did that - but I still don't get the verbose boot . .



Alternatively, you can keep hitting space bar during boot, and when the
menu comes up, edit the kernel boot line to remove them.  But this will
have to be done each time you boot.  Good for one time checks.



Yes, I do that occasionally but this is for a machine that has a "null" 
keyboard attached (I usually only ssh to it).


Thanks,

Phil.

People,

In the olden days I used to just edit the grub conf file and delete 
these args manually - now I am supposed to use grubby but doing this:


   grubby --update-kernel=ALL --remove-args="quiet"
   grubby --update-kernel=ALL --remove-args="rhgb"

does not make any difference to the boot information I see before the 
graphical login . .


What am I missing?



I do:

- sudo vi /etc/default/grub
- remove quiet rhgb
- and run:

[ -d /sys/firmware/efi/efivars ] && sudo grub2-mkconfig -o 
/boot/efi/EFI/fedora/grub.cfg || sudo grub2-mkconfig -o /boot/grub2/grub.cfg



- last line is ONE line -

GRUB2 removing args "quiet" "rhgb" - grubby doesn't work

People,

In the olden days I used to just edit the grub conf file and delete 
these args manually - now I am supposed to use grubby but doing this:


  grubby --update-kernel=ALL --remove-args="quiet"
  grubby --update-kernel=ALL --remove-args="rhgb"

does not make any difference to the boot information I see before the 
graphical login . .


What am I missing?

Thanks,

Phil.
