Setup console: http://ubuntuforums.org/showthread.php?t=329369&highlight=boot+console+font

console-setup

Install fonts, script and services

fonts are installed to /usr/share/consolefonts/
script: /bin/setupconm /usr/bin/ckbcomp
services: /etc/init.d/console-setup, /etc/init.d/keyboard-setup (they are installed to rcS.d)

Configuration:
1) $HOME/console-setup
2) /etc/default/console-setup
Note: if 1) exists, 2) will not be executed at all!!!

console-tools vs. kbd

console-tools provides consolechars. However consolechars cannot recognize some fontfaces provided by console-setup.
console-tools installs service console-screen.sh, makes dumpkeys process file /etc/console-tools/remap
update-rc.d console-screen remove
For example, I tried
consolechars –v –f /usr/share/consolefonts/Uni3-Terminus20x10.psf.gz --tty=/dev/tty5

It gives error

Cannot (yet) load a non-seekable RAW file
read_simple_font(): Invalid argument

I found this post http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg154310.html

I installed kbd (sudo apt-get install kbd). console-tools is automatically removed when you install kbd. Then I tried

setfont –v /usr/share/consolefonts/Uni3-Terminus20x10.psf.gz

It works!!.

kbd installs bunch of commands,

configuration: /etc/kbd/config, /etc/kbd/remap
kbd installs service console-screen.kbd.sh (installed to rcS.d)

Note: for both of console-tools and kbd, the installed services won’t be run if setupcon is present. In other words, if console-setup is installed, services installed by console-tools or kbd don’t run.

So, usually you should edit file /etc/default/console-setup to change configuration!!! Or copy it to your home directory.
Then use command
setupcon
to make it take effect immediately.
