• GRUB2 Tutorial

• Will it work on Steam Deck?

  No, stock SteamOS doesn't display a GRUB menu.

• What about Bazzite, ChimeraOS, HoloISO?

  Messing around with immutable distributions is not advisable.

• Can it work on my distro?

  This theme works on any mutable distribution that uses GRUB2 bootloader, such as Nobara.

• My resolution isn't supported!

  I can only test this theme on my laptop (2560x1600), the other resolutions are only guesstimates. PRs are welcome!

• This theme is bad / wrong!

  I am not a designer. This is my first GRUB theme ever. Move along.
