Scrollback not working in terminal window (ssh session)

Solution 1:

Add this to ~/.screenrc log out of screen and back in:

shell "/usr/bin/bash"
termcapinfo xterm* ti@:te@

Solution 2:

Screen disables the standard scrollback in your local X terminal, because it is actually a curses program behind the scenes. As Murali said, if you want to use screen's scrollback, you'll need to Ctrl-A esc and then use the regular keys (PgUp/PgDn/cursor) to look through the history. Escape will get you back out.
