Screen isn't a shell, it's a pty manager (can't call it a "window manager"
because it isn't graphical...).

Good choice. I'm using it right now, running in a x-terminal-emulator. It comes up at
login with a number of applications running in different ptys.

You should change that back to bash (or whatever) and just put:

screen

in your ~/.bash_profile (or whatever).

See above.

You are making it much too complicated :-)

The reason I run screen out of an x-terminal-emulator is that I want to have
easy access to the few graphical apps that I use, and booting X in a seperate
tty is slow and the change from text to graphical mode is a real strain on the
'system'. (there are also other problems invovled that can drive you nuts)

Here's what my ~/.xsession looks like:

#!/bin/bash

flwm -geometry 140X60+0+0 &
WindowManager=$!
aterm -bg darkgray -geometry 110X42+0+0 -e screen
wait $WindowManager

Flwm is a light window manager and aterm a light x-terminal-emulator.

Here's a great tip I got from someone a while back. It changes your
screen escape keybinding from Ctrl-a to Ctrl-Space, and your "other"
keybinding to y. Put them under KEYBINDINGS in your ~/.screenrc:

escape '^@^@'

bind 'y' other
