GRUB shows up by default, even though GRUB_TIMEOUT=0

[Jonas Gamao]

Here's my GRUB config:
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

It's annoying that it keeps showing up by default because it's only Kubuntu on this laptop.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug.

You didn't say what file your paste was from?

Did you perform `update-grub` to update the version that is actually used at bootup? or you're pasting the settings that will be used on next kernel upgrade?

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

The paste was from /etc/default/grub

I ran update-grub multiple times

I disabled OS Prober

The paste was from /etc/default/grub

I ran update-grub multiple times

I disabled OS Prober

None worked

Also, I'm using Btrfs, in case that helps

[Niklas Sombert (ytvwld)]

If I take a look at /boot/grub/grub.cfg I see the lines:

function recordfail {
  set recordfail=1
  # GRUB lacks write support for btrfs, so recordfail support is disabled.
}

So, I guess this is intentional, at least.

Are you booting via UEFI or BIOS?

I could at least reduced the timeout by setting GRUB_RECORDFAIL_TIMEOUT.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jonas Gamao (yamiyukisenpai)]

UEFI

Do I put GRUB_RECORDFAIL_TIMEOUT to 0?

[Niklas Sombert (ytvwld)]

you probably can, but you won't be able to enter grub anymore, so I wouldn't recommend it
