How To Make The Grub Menu Larger

After getting a new monitor everything was so small I could hardly see the font in the Grub Menu.

Finding the solution was pretty easy so here's what you can do.

In Debian/Ubuntu you can change the default GRUB resolution, thereby resulting in larger fonts on the GRUB menu:

1. Make a backup: sudo cp -a /etc/default/grub /etc/default/grub.bak

2. Open the configuration: sudo $EDITOR /etc/default/grub

3. Edit GRUB_GFXMODE entry to suit your resolution e.g. 800x600

4. sudo update-grub

5. Reboot; GRUB will display in the mode you set.

Don't forget to remove the pound sign in front of the letter G in the line GRUB_GFXMODE=.

Where the cursor is in this screenshot of the /etc/default/grub file that's the line your looking for to edit.

This is Slackware's grub file so yours will probably only have one entry for the GRUB_GFMODE= line.

With my Linux Mint 21 Cinnamon installation there was only one entry for the GRUB_GFMODE line. Not 2.
