Does it supports the ability to scroll back to see things ? That one got removed from the Linux console years ago and I miss it.

Seems like yes. There's keyboard shortcuts for scrolling listed here: https://cgit.freedesktop.org/~dvdhrm/kmscon/tree/docs/man/kmscon.xml https://cgit.freedesktop.org/~dvdhrm/kmscon/tree/docs/man/km...

  Perfect. In that case I'll be trying it out on a headless machine soon.

    FYI, seems like this fork is a lot more maintained, so you might have better luck with this. https://github.com/Aetf/kmscon https://github.com/Aetf/kmscon

You can still satisfy the need for scrolling by using NetBSD. (I use both Linux and NetBSD) With the --sb-size flag one can purportedly set the maximum lines of scrollback in kmscon.

If you are OK using gnu screen, you can auto spawn screen if tty is /dev/tty2 - tty6 (adjust if you allow logins on other ttys). Screen will mess up ability to run startx, but if not using X, use screen on /dev/tty1 - tty6. I do the above (via a shell snippet in /etc/profile.d) to get scrollback and an idle lock, via screen, on tty2-6, and, if tty1, add an alias that invokes vlock after startx exits to lock the virt console that X is using on exit from X. But, KMSCon looks worth checking out.

  Sticking with screen. Installed kmscon, manually ran kmscon on a single virtual console, switched back and forth from kmscon to X and back three times. On the third time, X shutdown like it detected a conflict (it looked like a crash, but the logs showed an orderly shutdown of X). Current setup with auto spawned screen instances is stable.
