How use grub font generated by grub-mkfont inb your own theme?

[hugo-is-hugo]

I have issue to load the pf2 font I have created using grub-mkfont

I tried to follow your steps here to create it: Creating custom fonts (.pf2) for GRUB] (https://github.com/VandalByte/grub-tweaks#-topics)

I run this command: sudo grub-mkfont --output=./DejaVuSansMono28.pf2 --size=28 /usr/share/fonts/TTF/dejavu/DejaVuSansMono.ttf

on a font that is local already on Ubuntu 24.04 (To make it easy to reproduce and we might use same font).

But when loading it in theme.txt like this. I only see the color take effect, but the theme font is not loaded (I use grub2-theme-preview look it there I see on command line they are loaded. However not in GUI)

+ boot_menu {
    ....
    item_font = "DejaVuSansMono20.pf2"
    item_color = "#919090"
    selected_item_font = "DejaVuSansMono30.pf2""
    selected_item_color = "#ffffff"
    ...
}

I saw that you loaded your font like this: item_font = "Norwester Regular 28"

in https://github.com/VandalByte/dedsec-grub2-theme

but the files in the dedsec had format:

norwester_24.pf2
norwester_28.pf2
norwester_30.pf2

How do you know what name to use in item_font? How do you create it in the font?

I found the answer my self.

I need to add the --verbose flag

sudo grub-mkfont --output=./DejaVuSansMono30.pf2 --size=30 /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf --verbose

Font name: DejaVu Sans Regular 30 Max width: 48 Max height: 39 Font ascent: 33 Font descent: 12 Number of glyph: 6288

The bold font name in the output is the name that I needed to use in theme.txt for the fonts.

+ boot_menu {
    ....
    item_font = "DejaVu Sans Regular 30"

Maybe the guide could clarify this step? Also thanks for a very good guide. Hope more start to create themes since very few nice theme beside yours.

Yeah so the file name has nothing to do with how grub sees the font file, what I usually did was, just put all the fonts that I wanted to test and list all that loaded fonts in grub command line, didn't knew about the verbose tho

If possible, add it to this section and submit a pull request so that others facing the same issue can easily find it or I'll try to add it when I get some free time. Cheers! https://github.com/VandalByte/grub-tweaks#%EF%B8%8F-creating-custom-fonts-pf2-for-grub
