Theme not being shown

[THN1]

Hi

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 me use of grub-customizer. So I launched it and selected/activated the darmatter 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.

Hi T
Personally, I have not worked with grub customizer nor Q4OS, but I did see that the OS is based on Debian so it should have worked properly without any issues. Can you snap a few screenshots of the files you see in the grub related directories or list them here. If I get some free time I will try out Q4OS in a VM and see if I can get it running. Also I suggest you check out here, maybe you might find something useful

Any news???
Q4OS is nothing else than Debian plus KDE Plasma desktop plus some tools, so I don't see why it shouldn't work.
Just beware that when testing with VBox, you probably must enable EFI BIOS.

Has been confirmed by the Q4OS admin team as a general Debian issue:
