Where is screen cleared before initial login prompt?

In the past the screen has not been cleared before displaying /etc/issue and the initial login prompt. I like that because sometimes errors and warnings are displayed that do not appear in any logfile.

Recently one of my 2 machines (probably the one I changed to baselayout 2) has started clearing the screen. Not good.

What do I need to change to prevent clearing?

Thanks

On my system, ~/.bash_logout calls clear_console:

Code:

# ~/.bash_logout: executed by bash(1) when login shell exits.



# when leaving the console clear the screen to increase privacy



if [ "$SHLVL" = 1 ]; then

    [ -x /usr/bin/clear_console ] && /usr/bin/clear_console -q

fi

So I could comment out those lines, if I wanted:

Code:

# ~/.bash_logout: executed by bash(1) when login shell exits.



# when leaving the console clear the screen to increase privacy



#if [ "$SHLVL" = 1 ]; then

#    [ -x /usr/bin/clear_console ] && /usr/bin/clear_console -q

#fi

You can edit /etc/skel/.bash_logout if you want to change the behavior for all new accounts, as well.

How is something in ~/.bash_logout relevant? No-one is logged in yet, so which one to use? I'm talking about clearing the screen before the *initial* login prompt is displayed.

This is the new default behavior in agetty. You can add --noclear in TERMINALS
section of /etc/inittab to avoid it.
Here's how that section should look to get the old behavior of not clearing:

Code:

# TERMINALS

c1:12345:respawn:/sbin/agetty --noclear 38400 tty1 linux

c2:2345:respawn:/sbin/agetty 38400 tty2 linux

c3:2345:respawn:/sbin/agetty 38400 tty3 linux

c4:2345:respawn:/sbin/agetty 38400 tty4 linux

c5:2345:respawn:/sbin/agetty 38400 tty5 linux

c6:2345:respawn:/sbin/agetty 38400 tty6 linux

It was in the post install message of sys-apps/util-linux-2.20.1-r1 - 02/27/2012

Code:

LOG: postinst                                                                                                                                                                                                                  │

│The agetty util now clears the terminal by default.  You                                                                                                                                                                      │

│might want to add --noclear to your /etc/inittab lines.

Hope that gets you all fixed up.
