That's expected behavior, presuming you are expecting the terminal to scroll
back through its history buffer.

The terminfo for both "Eterm" (the correct one for this report) and "xterm"
(just in case your shell overrides that) tell the terminal to use the alternate
screen when initialized (as by screen, vi, etc).

But in xterm and in console Shift+PgUp works. Why are they different?

They're different because they're separate developments, and it simply
was a feature that wasn't incorporated into rxvt/Eterm/aterm or their
obese cousin gnome-terminal (or its clone konsole).

Making the normal+alternate screen shift together isn't necessarily an
obvious thing to do.  (Offhand I didn't recall if xterm did it - had to
look).

Linux console of course is completely separate.  I don't know whether
the shift-pageup was adapted from xterm or minicom or some other source
(I've never seen a kernel changelog that could provide information like
this ;-).  Since it doesn't implement alternate screen, it's not the
same case, anyway.

 I don't know how you get scrollback with shift+pageup in screen in
 xterm, I don't by default.

 Anyway, Adam Lazur explaiend how screen can be configured to use the
 normal scrollback and how one can access screen's internal buffer with
 screen's copy mode in bug #326094.

 Hence, I'm closing this bug.  Please reopen it if necessary (or mail

I started an xterm, did a few ls's to put stuff into its scrollback buffer,
and attached to a screen session that I had running.  shift+pageup for xterm
did show me the new xterm's scrollback buffer.  (I first checked if I'd
any local resource settings for xterm).

That's what I would normally expect.  screen isn't really aware of the
terminal's own scrollback buffer, has its own.

To be fair, Marco is actually suggesting that these various terminal
emulators be modified to behave as xterm does. I agree that they don't,
but the problem is not really something that screen should know about.
The latter part is where I was disagreeing.

 Your explanation is welcome, I initially thought the reporter expected
 the screen session to be scrolled when pressing Shift-Up.

This can be fixed by adding:

# To get screen to add lines to xterm's scrollback buffer, uncomment the
# following termcapinfo line which tells xterm to use the normal screen
buffer
# (which has scrollback), not the alternate screen buffer.
#
termcapinfo xterm|xterms|xs|rxvt ti@:te@
