Console (TTY) Resolution on Ubuntu Linux boxes

Ubuntu installations come with 640 x 480 default config on console or TTY (Teleprinter/Teletype/Teletypewriter). To change that config to something readable:

– You need to edit /boot/grub/menu.lst
– To the end there are lines:
title Ubuntu 8.04.2, kernel 2.6.24-23 server
….
….
kernel /vmlinuz-2.6.24-23…

at the end of kernel /vmlinuz line we need to a new argument ‘vga’.

I mostly use vga=791

then update grub using:

# update-grub

and reboot.
