[SOLVED] Grub2 Menu not correctly formatted.

Postby laidlaws » Dec 18th, '20, 14:27

Running Mageia 7.1. The Grub2 menu is not in the format I am accustomed to, but is ordinary single-spaced white text on a (approx BSOD) blue background. Everything works as it should, so I can live with it, if I have to. I can see nothing obvious in the config files, and Cauldron seems O.K. Where should I look? Is there a CSS somewhere?

What theme is configured in /etc/default/grub ?

The theme is the default theme. Last night I switched to the dejavu theme, annd it showes up OK. Current line is:

Code: Select all
GRUB_THEME=/boot/grub2/themes/mageia-dejavu/theme.txt


Just hold on while I switch back to the default one.

Everything seems to be O.K. now. with the default "maggy" theme. Maybe all the swapping around blew out a few cobwebs.

Thanks anyway, Doktor.

This has returned. A reply on an Ubuntu forum says that it depends (among other things),on "the phase of the moon," In that case, and with Mga-8 almost ready for release, I will just live with it.

Hmmm, what does this have to do with Ubuntu ?

I'd say this is more something about your setup or modifications, as I've never saw or heard something similar before you reported this.

> Hmmm, what does this have to do with Ubuntu ?

Just that every distro uses Grub2, and there may be clues there. I did find a couple of cases, one on Ubuntu, one on Arch, but they resisted all attempts to solve them. Those helping could not reproduce the bug.(That was the point of the comment about "phases of the moon," meaning that Grub2 can misbehave for no ascertainable reason at all.)

Watching the output of "update-grub"' the first line in Cauldron is: "found theme, ..."

That line is NOT PRESENT in 7.1. So, like the other cases, I only have to find out why. All permissions look O.K. It works O.K. in Cauldron.

I did an "Upgrade" install from a USB key. I find that it will often fix strange happenings like this one. This time, it worked again, I have a normal Grub2 boot menu.

I just had to reinvent the wheel. The Grub2 menu was a simple text listing. The line specifying the theme was missing from /etc/default/grub just like before. I added the line:

Code: Select all
GRUB_THEME=/boot/grub2/themes/maggy/theme.txt


ran "update-grub" once more, and the problem went away.
