Bug 442182 – app-misc/screen-4.0.3-r5 freezes with default configuration

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Pavel Šimerda 2012-11-07 11:42:45 UTC]

The 'screen' program freezes at start (shows no output, doesn't react to any
keys). When connecting over SSH, I use enter ~ . to drop SSH connection and
connect again. According to strace, it runs pause() and there it stays.

But, if I move away /etc/screenrc, screen works.

Plus, when I remove:

silencewait 15                      # default: 30

Running 'screen' just kills the SSH session.

silencewait 30 does the same, so it definitely is not the default as is suggested by the configuration file

[Comment 3 Pavel Šimerda 2012-11-07 12:19:17 UTC]

Simplest configuration file that freezes screen:

  silencewait 15                        # default: 30

Simplest configuration file that tears down SSH connection:

  pow_detach_msg "Screen session of \$LOGNAME \$:cr:\$:nl:ended."

When I remove both of them, I'm getting something that looks like
a split screen but screen only uses the upper half of the reals
screen.

This can be fixed by also removing:

  startup_message off

However, I don't know how to fix this properly and make it work
with the Gentoo default options.

Can you include the strace as an attachment?
