Blanking Console Screen

[ksiu]

Hi,

How do I get the console screen to automatically go blank when there is no keyboard/mouse action for a period of time?
Right now, the console screen stays on forever.

By console, I mean the login screen right after I boot up the computer, and before I type "startx".

And this is a Thinkpad T440P laptop. Thanks!

sleep n + clear in ~/.bashrc? x11/xlockmore?

sorry, I meant automatically go blank.

vidcontrol -t N where N is in seconds.
If that works, there should be a hook in /etc/rc.conf (or /etc/defaults/rc.conf) named blanktime or something that should get called from somewhere. It's been a while since I've tried or used it.

What mer said is probably what you're looking for if you want to put the screen to idle. I understood that you wanted to clear the framebuffer between login and startx, I bypassed the keyboard inactivity and transcribed in my mind blanking (empty) to clear up.

x11/xlockmore -> security/vlock, I meant

You could also poke around /etc/ttys.
The FreeBSD bsdinstaller script has a Hardening option for -Secure Console-
It should have a setting for time before it blanks.
As seen on line 84 of /usr/src/usr.sbin/bsdinstall/scripts/hardening

sed "s/unknown    off secure/unknown    off insecure/g" $BSDINSTALL_CHROOT/etc/ttys > $BSDINSTALL_TMPETC/ttys.hardening

Configuring tty for incoming connections

I have a serial port on my server which I want to connect to. But when I try to connect to this port via console cable, I can not see any outputs on the screen but I can hit any keys as inputs. The related device is /dev/ttyu2. Here's my relevant part of my /etc/ttys file: console none...

This will autologout on FreeBSD default tcsh shell after 1 minute.
set -r autologout='1'

Like mer said to truly blank (without involving suspend) you need vidcontrol.
In /etc/rc.conf

blanktime="300"

Broken on FreeBSD vt(4) terminal

233356 – 12.0-RC1 vt(4) doesn't support rc.conf parameters saver= or blanktime=

Phishfry that's interesting. I believe vt is the default console device instead of syscons. And that it's been that way for a bit. Interesting. Implies folks are probably doing power related stuff (is there a console equivalent of the xset dpms?)

Ed Maste commented on that PR that a setting needs to be added.
On my 12.2 codebase it is fixed from my viewing.
Yet blanktime the setting does not work for me.

Hmm. Curiouser and Curiouser.
