Why 6 ttys running?

[daKoolaid]

I do a cold boot but System Monitor shows 6 tty processes. Why is this? Is it safe to disable 2-6?
Thanks in advance!

What is the harm?

You probably can, I don't see why though. They are so incredibly small... disabling them will save you around 100kb of memory.

Ok. So this is not a security risk to have them running? Then I have no problem leaving it alone.

try running this in terminal

ps -e | grep tty

my output is here

# ps -e | grep tty
1116 tty7 00:01:06 Xorg
1654 tty1 00:00:00 agetty

This will give you some idea what each one is for

hi
i presume it's save to reduce the number of getty processes in /etc/console-setup.
you have to change: ACTIVE_CONSOLES="/dev/tty[1-6]" to your behavior.
but i can't guarantee that lightdm will notice this "F1-F6". just give it a try.
i hope it's not hard coded anywhere.
no risk no fun
cheers

No more or less of a security risk than having a login screen...
