Grub not showing despite being set to not hidden
I have dualboot bluefin and bazzite on separate ssds. the setting is the same on both distros (not hidden) but in both cases I do not see grub menu when booting up
Running ujust reconfigure-grub doesn't change anything

give us your
/etc/default/grubGRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.luks.uuid=luks-c023cf83-a49e-4a26-a93c-de4a69b1d101 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
is this a desktop?
you can increase the timeout from 5 seconds to something higher then do
ujust regenerate-grub
might be that it is showing up but it boots the default option by the time it is displayed on the monitoryeah its a desktop. just increased the timeout to 15, no change
do you have multiple monitors attached?
i know some people use the machine as a htpc and dont always have all monitors on, the grub menu might appear on one that is off
other than that i dont really know why it does not show up for you
Or it also is possible that your firmware directly loads the kernel…
What’s your current boot order?
yeah it has multiple monitors, i will try booting with just one plugged in
current boot order is
-bazzite
-bluefin
I will also try swapping the order and changing bluefin timeout to see if that makes any diff
ok so:
i tried with individual monitors plugged in, no change. when i swapped the boot order from bazzite > bluefin TO bluefin > bazzite, the grub appeared when booting up bluefin. it only showed the bluefin os trees, so i ran
ujust reconfigure-grub and rebooted. after reboot, the grub did not appear.
I switched the boot order back to bazzite>bluefin, and on first boot the bazzite grub showed up, but only with bazzite os trees. I will try running the reconfigure grub command again but i imagine it will have the same effectHmmmm I would say try checking your
/boot/grub2/grub.cfg on both bluefin and bazziteI have the same problem. Grub doesn't show up during boot.
Bazzite runs in desktop mode and is the only operating system. Grub is set to 'Not Hidden'.
/etc/default/grub looks identical to the one above.
/boot/grub2/grub.cfg:
terminal_output console
if [ x$feature_timeout_style = xy ] ; then
set timeout_style=menu
set timeout=5
# Fallback normal timeout code in case the timeout_style feature is
# unavailable.
else
set timeout=5
fi
This is probably the correct section.
What I tried:
- added GRUB_TIMEOUT_STYEL=menu to /etc/default/grub (and rebuild the grub.cfg file)
- deactivated auto-loginthis fixed the issue for you?
No. This is just what I tried but didn't work.
Both fives are 0 on my device with grub hidden so this part is correct
Just checked that grub menu is showing when I choose to unhide

My grub.cfg when unhidden for comparison
I compared it to my .cfg file. Those are the differences:

But the
timeout in this part can be the problem I presume…?You mean it's too short?
I at least got it too show up when pressing the left arrow key during boot.
I mean something probably changed because there are multiple OSes
I don't have multiple OSes. Only Bazzite.
I didn't format the SSD before installing Bazzite, though. Just installing it over Tumbleweed with the delete option during install.
Try adding these two lines to the end of your grub.cfg
set timeout_style=menu
set timeout=5
Will be undone if you configure grub again but should work for now And reconfigure grub after booting back once
please for the love of everything dont edit grub.cfg directly
just add
GRUB_TIMEOUT_STYLE=menu and GRUB_TIMEOUT=5 to /etc/default/grub and regenerate grub with the ujustI personally suspect it’s the show once rule interfering
I already tried that. Didn't work.
im responding to @Linus Xu suggesting to edit the grub.cfg directly to add them.
editing it directly is literally a footgun and there is a reason you just add the grub variables you want to the defaults file and regenerate grub
And I agree with this
Just that I’m trying a temporary workaround here…
