All it takes to implement a new theme is ...

Code: Select all

sudo nano /etc/default/grub

...

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=3
GRUB_THEME=/boot/grub/themes/poly-dark/theme.txt

...

sudo update-grub

If the LM theme is sticking around then you might have to move the LM theme config files out of ls /etc/default/grub.d/. Other than that, clean install and don't use that thing.

You can also edit the 60_mint-theme.cfg file in the \etc\default\grub.d folder. By default it reads this:

Code: Select all

#! /bin/sh
set -e
GRUB_FONT="/boot/grub/fonts/UbuntuMono16.pf2"
GRUB_THEME="/boot/grub/themes/linuxmint/theme.txt"

Just change it to your theme-specific files.

Code: Select all

#! /bin/sh
set -e
GRUB_FONT="/boot/grub/themes/fallout-grub-theme/fixedsys-regular-32.pf2"
GRUB_THEME="/boot/grub/themes/fallout-grub-theme/theme.txt"

I suspect the folks that write custom GRUB themes will update their install scripts to include altering this file.

Note: If in your theme's Icon folder (/boot/grub/themes/ThemeName/icons) you have a PNG file named linux-mint.png, renamed it to linuxmint.png and Mint 19.3 will use it. The Fallout GRUB theme still uses the old linux-mint.png nomenclature.

Either edit the theme.txt file to point to the correct image, or simply replace the theme's image with your own by copying your image over the top of the original using the original name.

If you are using Mint 19.3, go into the \\boot\grub\themes folder and find the default theme for Mint. In that folder, go into the Icons folder. In there are the names of the PNG files that Mint 19.3 will recognize. Just match up those names with the ones from the theme you want to use. That's how I found out it is no longer linux-mint.png but linuxmint.png.
