Hi,

I try it on my VM with sid, it is working now.

Some enhancements could be done:

If you put an image in `/boot/grub` the settings, e.g. the normal font color, will be reset to default (and the background will be the image).

If grub-customizer doesn't found the image, e.g. you put it on LUKS partitions, all the settings will be reset to default.

Best regards

Ok, this bug may close.

I'd do the test in my notebook.
When I put an image and font settings, the font setting is also not to become affect,
but the display color of the font is take affcet.

The /boot/grub/grub.cfg updated like this:

if background_image /atzlinux/IMG_2021.jpg; then
set color_normal=green/black
set color_highlight=red/light-cyan
else
set menu_color_normal=cyan/blue
set menu_color_highlight=white/blue
fi

If grub-customizer doesn't found the image, e.g. you put it on LUKS partitions, all the settings will be reset to default.

Is grub support LUKS partitions now?
grub is a bootloader, it's start before kernel, LUKS is supported after kernel load.

Best regards

Thanks!

O, I test again, the font setting is take affect.

atzlinux@debian:/boot/grub$ file unicode.pf2
unicode.pf2: GRUB2 font "MingLiU Regular 28"

From info grub:

7.2.2 Fonts
-----------

The fonts GRUB uses "PFF2 font format" bitmap fonts. Fonts are
specified with full font names.

so select the bitmap fonts in grub-customizer is OK.

Regards.

Can you make it use always the first color values?
(And eventually other values like fonts etc.).

When "else" it's triggered.

So if grub doesn't find the image at least the other changes are applied.

I think this is the upstream logical.
If no background image finded or checked, the font color will use default color.

If no background image, there is not need to tune the font color, this also meet the most situations.
