Inspired by the blog post [Increase Font in GRUB for High DPI Screens](https://blog.wxm.be/2014/08/29/increase-font-in-grub-for-high-dpi.html) from Ward Muylaert. I decided to try to make it work under Fedora 32 on a system which uses EFI boot.

First make the font compatible for grub:

```sh
$ grub2-mkfont /usr/share/fonts/dejavu-sans-mono-fonts/DejaVuSansMono.ttf --size=48 --output=/boot/efi/EFI/fedora/fonts/DejaVuSansMono48.pf2
```

Next update the grub configuration:

```sh
$ sudo grub2-mkconfig -o /etc/grub2-efi.cfg
```

Strictly speaking not required, how-ever I like to keep the files in sync:

```sh
$ sudo  grub2-mkconfig -o /etc/grub2.cfg
```

Alter content of file:/etc/default/grub to include font reference. The GRUB_TERMINAL_OUTPUT is optional, it should be included by default when specifying a new font.

```
#GRUB_TERMINAL_OUTPUT="console"
GRUB_TERMINAL_OUTPUT="gfxterm"

GRUB_FONT=/boot/efi/EFI/fedora/fonts/DejaVuSansMono48.pf2
```
