Grub background configuration

marky · 2017-02-20 12:03:12

Hi,

Where I can find some guidelines to tweak a little the boot window content like text and things like the rectangular border, please?
I followed this https://wiki.debian.org/Grub2 site for tips and the image shows up already but the rest doesn't.
I mean after editing the /etc/default/grub file.

For instance the console menu color set by

set color_normal=blue/black

command is ignored after

update-grub

command.

Also I'd like to get rid of that rectangular border and additional descriptions below..
I love the Bunsenlabs distro for a beauty of the minimalist UI idea and would like the boot window to follow.

Still consider myself as a linux newbie, though.

Thanks,
m

^ That link says

The easiest way to modify the console menu colors is to create a new file /boot/grub/custom.cfg and put your configurations there:
(Your Example)
set color_normal=blue/black
If you configured /boot/grub/custom.cfg, there is no need to run update-grub; the file will be automatically loaded by /boot/grub/grub.conf at boot

There is also an interesting tool called Grub-Customizer. For Fedora it's in the repositories (not for Debian), but it can be installed on Debian too.

^ Confirm that it builds and installs on BL. There is a README in the tar.gz that describes the steps, and dependencies required.

After reading about it in a detailed magazine article - saying the .deb 5.0.6 for Ubuntu 14.04 works fine on Debian 8 - I did download the file "grub-customizer_5.0.6-0ubuntu1~ppa1t_amd64.deb" from here and installed it via gdebi.

It is still installed and starts fine for me. It's possible to tweak the Grub entries - move up and down, set the time for default, etc. - and change the background under Appearance settings. After "save" it generates a new "grub.cfg".

Thank you guys.

I know already grub-customizer and experienced the following output:

1. Full control on Fedora.
2. Background and text color on Mint/Ubuntu, still rectangular border, though.
3. Just the background picture choice on Debian, no matter what I choose in the background configuration tab

Anyway, I started to play a little with that custom.config file and at least I can change a picture resolution size.
That pdf file is I guess the best source to acquire knowledge about it, a little overwhelming in size - 108 pages, though.
Hopefully I'll find some more time for that on next weekend.

To get what I need it is necessary to go through the following:

1. For the text contents and order on the list: Grub customizer, it picks up whatever is listed below, no matter what I set in it.
2. For setting background picture: /etc/default/grub
3. For setting the font color: /boot/grub/custom.cfg

And the ugly rectangle still mocks on me...

Is it possible to be able to use for that one command like for instance in fedora:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

- after setting all in grub customizer?

Thanks,
m

AFAIK you don't need to update grub after changing grub.cfg. It is sourced by the grub boot process, as well as any custom config files, so any changes should show up.

marky · 2017-02-23 18:26:26

"..so any changes should show up"

But they don't.
What I experienced was that boot window opens up picking up ONLY whatever is related to the color of the text from custom.cfg file as the source of grub.cfg. And that's all, no matter what background is listed there.

For the background picture to be changed I have to go to another file, as mentioned before...

damo · 2017-02-23 18:33:29

Let me change that to "..so any valid changes should show up". The custom.cfg I posted, with font colours, showed up immediately when I tested it.

I haven't investigated the container's borders, so I can't help much with that. The first thing I would investigate is Styled Box.

marky · 2017-02-23 19:10:03

Right, that's what I'm saying. The font colors is the ONLY changed I can make to be included in boot window.

This is a good themeing resource for Grub2: http://wiki.rosalab.ru/en/index.php/Gru … e_tutorial

I infer from this that the console background has a hard-coded 3px border.
