grub theming [SOLVED]

THN · 2024-08-28 18:01

Hi forum

I'm wondering if anyone of you guys has experience with grub theming. I'm using grub customizer and can't get my theme to load/display.

What I've done so far
1) I went to https://github.com/Jacksaur/Gorgeous-GRUB and found a nice looking debian theme as part of the "dark matter" theme set
2) I went to dark matter's site https://www.pling.com/p/1603282/ and downloaded the debian-1080p.zip file
3) I unpacked the archive to a folder under /home/myself and ran the installer command ("sudo python3 darkmatter-theme.py -i")
So far, all went well (no error messages)

I rebooted but didn't notice any change. So I thought this must be because of my use of grub-customizer. So I launched it and selected/activated the darkmatter theme, which has become visible/available in one of the tabs, and saved the updated configuration.

Again, after reboot there was still no change.

So I went through the chain of boot files, to see where there might be the error.

First, from the EFI Bios, I boot the file /boot/efi/EFI/q4os/grub.cfg which only contains
search.fs_uuid 7e23d27b-4781-4b46-b798-53d7c0ab9fb9 root hd0,gpt9
set prefix=($root)'/boot/grub'
configfile $prefix/grub.cfg

So from here the boot branches to the "real" grub.cfg file in /boot/grub/ which contains the following theme instructions:
### BEGIN /etc/grub.d/05_debian_theme ###
set menu_color_normal=cyan/blue
set menu_color_highlight=white/blue
### END /etc/grub.d/05_debian_theme ###

When I check /etc/grub.d/05_debian_theme, I find that this is the original Q4OS theme file stemming from the Q4OS installation (dated February 2023)

So "somewhere" in the chain of configuration files, the "link" to darkmatter's debian theme (residing in my home dir) is missing and wasn't correctly installed.

What am I doing wrong and how can I activate my theme?

Best,

T.

We will take a look and post back a bit later.

Please post some more info about your system. Desktop environment, Desktop profile you have applied, iso file you have installed from and output of terminal commad:
$ get-q4os-version

We can confirm this issue, as we have made testing on Q4OS 5 and plain Debian 12.
- testing on efi based virtual machine
- downloaded the debian-1080p.zip file
- extracted the zip file
- installed with command:
$ sudo python3 darkmatter-theme.py -i
-reboot
The Grub theme didn't apply neither for Q4OS nor Debian. So we conclude Debian upstream issue. As this isn't native Q4OS issue, we suggest you to search for a fix for Debian and apply it on Q4OS. We will try to investigate further however it could take some time.

Since I don't get any answer from the theme author
(https://github.com/VandalByte/darkmatte … /issues/43)
I would appreciate if you could have a look (again)

Thanks,

T.

IMO, skip the installer.
In the extracted files, copy the darkmatter folder to the /boot/grub/themes/ folder (create if it doesn't exist)
Edit /etc/default/grub, adding the line
GRUB_THEME='/boot/grub/themes/darkmatter/theme.txt'
Then do a grub-mkconfig -o /boot/grub/grub.cfg, you should see a blurb about "found grub theme".

next time you reboot, you'll be using the darmkatter theme.

No, it doesn't appear to be that simple.

First, the installer has already copied the full set of files to /boot/grub/themes/darkmatter/
Second, the entry
GRUB_THEME="/boot/grub/themes/darkmatter/theme.txt"
is well present in the file /etc/default/grub

But still, the command
grub-mkconfig -o /boot/grub/grub.cfg
doesn't show "found grub theme":

$ sudo grub-mkconfig -o /boot/grub/grub.cfg

and the theme also doesn't show up upon reboot from EFI BIOS.

Maybe this Grub theme works for legacy BIOS only, but not for UEFI ? Did you try to set it up on another Debian based distro or a plain Debian ?

No, Q4OS is my only plain debian distro.

It most definitely works, I'm using it on one of my own installs. That's how I know exactly how to set it up.

THN · 2024-09-21 08:31

No it doesn't, as confirmed by Q4OS Team (see above).

q4osteam · 2024-09-21 10:22

Could it be related to https://bugs-devel.debian.org/cgi-bin/b … bug=954405 ?

THN · 2024-09-21 16:17

Thanks for the idea, allowing another test.
This time, I disabled /etc/grub.d/05_debian_theme before running
sudo grub-mkconfig -o /boot/grub/grub.cfg
but the theme sadly still doesn't show up.

q4osteam · 2024-10-17 09:45

@THN
We have investigated a bit and found a possible clue. You may need to comment out "GRUB_TERMINAL=console" in "/etc/default/grub", setup the custom Grub theme again and report back.

THN · 2024-10-17 09:59

This has done the trick!
Thanks a lot!

Thanks for the feedback, we will make an update to Q4OS for the next release.
