Hi all,

For some reason all the ttys are frozen up; I can switch between X

ALT+Fn.

Can you start new xterms? When you say 'frozen', do they "not accept
keyboard input"? Is it possible scroll-lock is enabled? What about
the TTY that you started Xorg from?

Is this temporal? When did it start happening?

Is there anything in /var/log/messages?

Good questions; I should have explained the situation a bit more.

I can start as many xterm as I'd like to. In fact when I'm in X
everything is alright.

I was doing some ports compilation on ttyv2 and
in the midst of that I remembered I forgot to pass a switch to compiler.
I pressed CTRL+C and it stopped but ttyv2 also stopped responding to any
keyboard events (even the mouse doesn't appear there).

Now when I switch to ttyvn by pressing ALT+Fn, it always switches
to ttyv2 with the same text shown as the moment it stopped working.

I killed all the ttyvn processes. They terminated and restarted as
expected. Now they all have different PIDs than before but still I
can't use them.

It's the first time I'm encountering such a problem.

I looked through dmesg output or in /var/log/messages but there was
nothing unsual out there.

Did you try: $ sudo pkill -HUP init ?

Will give it a try.

BTW, this is the my home machine just for personal use; it thus doesn't
hurt anyone if I restart the system but I'm just curious to know how
one can get out of such situation.


I tried killing them; they terminate and restart but still
frozen. I don't believe the only way out is to restart the system.

How to make ttys behave normally? I'd appreciate any idea.
FreeBSD 6.2-RELEASE-p7

Thanks,
