[SOLVED] Grub is not using the updated config after making changes

11 June 2023, 22:29:16

Hello everyone, I am having a weird problem with my grub config. For some reason after updating it with different methods (update-grub, grub-mkconfig command, and even grub-customizer) the config does not load the theme I set up along with linux-zen and linux-lts kernels on the list. I have looked around and can't seem to find an answer to this problem. This issue started right after an update to grub a while back but left it alone as it wasn't a big issue. Now I wanted to tackle it but with no luck. Does anyone have a clue on what can be done? I will upload an image of the output of what set gives on the command line. My installation is also UEFI if that helps. Sorry if this a noob problem but I don't know what can be done at this point. Thanks for reading!

Hello,
Have you looked in /etc/default/grub ?

Yes I have the GRUB_THEME uncommented and the directory it points to does exist in the themes folder. Not sure why grub just ignores it unless for some reason its reading elsewhere.

I'm using LTS (updated) and gave it a try.
I indicated the path to an image located in /home/user
After saving the change, I ran sudo update-grub
And it works.
I don't know if it can play, but the size of the image corresponds to the resolution of my monitor.

Code: [Select]

# Uncomment one of them for the gfx desired, a image background or a gfxtheme
GRUB_BACKGROUND="/home/jp/Images/2020-04-26_09-21-12.png"
#GRUB_THEME="/usr/share/grub/themes/artix/theme.txt"

I tried it with a theme and a png file on my home folder and it still doesn't budge. I took a picture of my thinkpad's set output and noticed that it has an extra line with the theme in place. I don't know if the msdos1 and msdos2 is causing something (sorry for my ignorance if that is not the case).

I'm not a grub expert.

Can you provide a copy of your /etc/default/grub file to compare to what I have ?
Or :
cat /etc/default/grub

Not much difference.
However, you have:

# you can see them in real GRUB with the command `videoinfo'

And me :

Yeah the auto came from grub-customizer and it worked before the update (it's the same on my thinkpad and it works). I'm going to mess around the resolutions and see if something happens. Maybe someone has some insight on this. The last thing I can do is probably rebuild grub but that might be overkill. Thanks for taking time to help out.

Not answering
I have similar or related problem i.e. the font size not taken effect when the /boot/grub/grub.cfg's line pointing the font size, indicated directly on the file name, is being changed

file name path does exist as reference by that line though haven't checked, and don't know how to, the file is correct in sizing the font image

Have you tried redoing grub-install, you will need to figure out the correct args for your particular system:
https://archlinux.org/news/grub-bootloader-upgrade-and-configuration-incompatibilities/
Another possibility is whether you might be booting using the grub from another partition or OS in which case you would need to make the changes there.

I haven't tried redoing grub-install but it seems that might be the only option. I will check it out and see if does the trick.

One little completion if I may, something that arch wiki page is imo ommitting, it's that on simple uefi installs, just running 'grub-install' should work to autodetect everything.
Spoiler (click to show/hide)

And even when it doesn't this one liner should cover it (mind you it's meant for a simple install so no dual boots and other fancy things)

Code: [Select]

if [[ -d /sys/firmware/efi ]]; then grub-install || grub-install --target=x86_64-efi --efi-directory=esp_mount --bootloader-id=grub; else grub-install "$(df /boot | grep -o '/dev/sd[a-z]')"; fi

I just tested: it actually works !

I am happy to say that doing grub-install worked. I wonder why it was necessary to rebuild it but I will take it. Thanks everyone for the help.
