For those of us grey beards who remember a simple 80x25 text terminal (or a C64 user who longed for 80 cols). This is the article for you.
Linux can still be run in a non-graphics mode, however if you are running any kind of a console server the cols and rows don’t match up. Here are some steps to set your linux console to 80x25.
This really depends on your boot loader (grub, extlinux, lilo, silo, raspi). The resolution you need to get to is 1280x720.
Add the following to your /boot/firmware/config.txt
framebuffer_width=1280
framebuffer_height=720
The kernel options can actually change your resolution after the boot loader. Use the nomodeset option in your kernel command line
Append nomodeset to /boot/firmware/cmdline.txt
The only console font that would create an 80x25 terminal is VGA 16x28 at the 1280x720 resolution:
Set the following in your /etc/default/console-setup
FONTFACE="VGA"
FONTSIZE="16x28"
VIDEOMODE=
To save yourself the trouble of manually rows and columns this command makes it very easy:
set | grep -E "^COL|^LINES|^TERM"
