Resize font on boot message screen and console

You can configure the font on tty console with

sudo dpkg-reconfigure console-setup

leave all settings as they are but the last one, where you can chose the size.

(You have to reboot to get the new font on your console.)

Update:

This doesn't seem to work anymore on 15.04, but you can install the custom Ubuntu fonts for your console:

sudo apt-get install fonts-ubuntu-font-family-console

And create a script /usr/local/bin/fontset with this command:

#!/bin/sh
setfont /usr/share/consolefonts/Uni3-TerminusBold32x16.psf.gz

(choose the desired font out of the folder /usr/share/consolefonts/)

You can either call fontset each time on your console after using Ctrl+Alt+F1

or add these lines to your ~/.profile:

#load larger font on tty
if [ "$TERM" == "linux" ]; then 
 #sleep 1 # add this if you have problems
 /usr/local/bin/fontset
fi

This starts your script only if you are on a tty console.
