using greetd with agreety on tty1, upon boot when the daemon is started, the console is cleared. when instead using agetty/login, the console output from kernel/init is preserved.
is there an option to achieve the same behavior here?
agetty clears the screen by default before prompting for the login name. See
man agetty, description of the "-J, --noclear" flag. The code can be seen here: https://github.com/util-linux/util-linux/blob/1e0ad14b3ac08d855cda6de346a65f9b834e00db/term-utils/agetty.c#L1275The clearing is actually done by greetd before activating the terminal, not by agreety. It could be made optional, but the current behavior intended to best simulate a normal text-based greeter setup (like agetty+login or ly).
indeed, my distro uses -J or --noclear for tty1 only, and i was looking exactly for that option within agreety/greetd. it would be a useful option imo.
