I am using screen for two years in Solairs and Linux. Before adding it
to your start profile consider this case   also. Some time screen –x
will hung can't even accept break signal, in this case you can't even
get the shell prompt. Your locked, we need to login as super user and
kill the screen session.

I have small script as ws, I will run after my login.

[ -f /usr/local/bin/screen ] && {

       #Check for exisintg screen session
       SSID=`screen -ls | perl -lane 'print $F[0] if /^\s+\d+\.work\s+/ ' `

       if [ -z "$SSID" ] ; then
               # if empty create new screen
               screen -S work -s bash -T xterm -c $HOME/bin/.work-screenrc
               # connect to exising one
               screen -xA $SSID

Yeah, I guess .login would be the correct place for csh.  Long time since
I used csh (or tcsh), but I guess something like:

if ("$STY" != "") then
   exec screen -dR
