I would like to force GNU screen to reflow to the existing terminal width when I reattach a session. It seems to me this worked properly before I upgraded a machine to CentOS 6, but I cannot figure out how to restore it. (TERM=xterm)

Whenever I reattach a session, regardless of state when I detached it, it launches at 80 columns, resizing my terminal (PuTTY, in this case) along with it.

I'm launching & reattaching with:

screen -aA -R <session>

My .screenrc contains only the following, and a few irrelevant key bindings:

term xterm

defscrollback 10000

# status line at the bottom
hardstatus on
hardstatus alwayslastline
hardstatus string "${-}%{.0c}%-w%{.y0}%f%n %t%{-}%+w %=%{..G}[%H] %{..Y} %D %M %d, %Y %c | Load: %l"
caption splitonly "%{.yK}%3n t"
caption string "%{.c0}%3n %t"

vbell off

# Fix fullscreen programs
altscreen on

You might have better luck with tmux, I can dynamically resize my Terminal window and the tmux inside will follow. –  number5 Nov 13 '13 at 23:15

after you reattach a ctrl-a F runs the "fit" command to resize the current window. if you reattach using the -A option it should resize all windows when you reattach. Are there others still attached to the screen session when you are attaching? For instance, are you having to use -x to reattach instead of -r? you can detach others when you reattach with "screen -D -r" instead of "screen -x", and I'd expect this to automatically refit windows.

I am launching with -a -A, and no one else is attached. –  Michael Dec 13 '11 at 15:49

Try adding this (from /etc/screenrc) to your ~/.screenrc:

# Change the xterm initialization string from is2=\E[!p\E[?3;4l\E[4l\E>
# (This fixes the "Aborted because of window size change" konsole symptoms found
#  in bug #134198)
termcapinfo xterm* 'is=\E[r\E[m\E[2J\E[H\E[?7h\E[?1;4;6l'
