The staircase effect - agetty

tucuxi · 2021-02-28 13:44:58

From https://wiki.archlinux.org/index.php/Getty:

agetty [...] modifies the TTY settings while waiting for a login so that the newlines are not translated to CR-LFs. This tends to cause a "staircase effect" for messages printed to the console.

What could be done so that messages appear without the staircase effect?

I have never witnessed this first hand. Can you describe what happens when it happens?

Sure, this appears briefly during the shutdown sequence: https://ibb.co/G9X84yB

Oh that! I have seen this indeed. No solution unfortunately.

Is the question regarding agetty or during "regular" use of an interactive shell?
For the latter, run "stty onlcr".

Otherwise

You'll basically have to alter the terminal w/ some service - whether that's a good idea is a whole different matter.
If this is just for cosmetic reasons, rather leave it alone. I don't know why but am pretty convinced that agetty doesn't set the terminal to raw mode for no actual reason.
