Could you please check whether its terminfo carries the required
definitions? In ncurses sources, that's misc/terminfo.src
The relevant parts are:
.--====
# The 3.0 kernel adds support for clearing scrollback buffer (capability E3).
# It is the same as xterm's erase-saved-lines feature.
linux3.0|linux 3.0 kernels,
E3=\E[3J, use=linux2.6,
# This is Linux console for ncurses.
linux|linux console,
use=linux3.0,
`----
I believe the first part was added first; if that's true it's possible this
will work for you:
TERM=linux3.0 clear
I'm not sure what Gentoo does to clear the console during logout: it might
just invoke "clear" (or its underlying ncurses implementation), it might
carry a copy of Debian's "clear_console"[1], it might do something else
entirely.
Meow!
[1]. It originally came from Ubuntu, forked there from "clear".
