Screen has odd blank out behaviour

[Ed Wagner]

Hello,

I use Apple OS 10.5.5 Terminal.app ,xterm  and Ubuntu Xterm in Gnome.   
I'm all for CLI and spend most of my time there either on local or  
remote machines which lead me to use gnu screen to save state and  
other handy features.


this issue I have is easy to resolve when not using screen and I feel  
I have isolated the issue to GNU screen and will aproch there user  
list next.  but I have been searching and reading up on the man pages  
for a while now and feel its time to ask if others have a solution.

This the  the famous screen clear on exit.

this is fix on all my systems that needed the fix. ssh or direct login  
on all systems works they way I wish.


Enter screen.

No there are a few different methods I have tried:

> infocmp >.terminfo/screen.xterm-color.terminfo
> cd .terminfo
> emacs screen.xterm-color.terminfo
#
# changed line 2
|#       Reconstructed via infocmp from file: /Users/ewagner/.terminfo/ 
78/xterm-color
|xterm-color|nxterm|screen-xterm|screen-xterm-color|generic color xterm,
> tic screen.xterm-color.terminfo
> sceen

this does not work, I've also made sure that LESS is unset and that  
TERM is not set in my profiles thus everything works outside of screen.



Now the odd part:

Is seems screen is doing something odd.  for if I export LESS=-X   the  
screen does a full clear and the prompt is at the top.

if I use clear or ctrl-l  the screen clears and places the prompt at  
the top.  but if I emacs or less.....  the prompt remains at the same  
level on the screen but all the characters are missing... or that is  
to say there apear to be 'blank lines' where the content was before  
and the prompt is left one line down from before I invoced emacs or  
less..

This lead me to think it was the autonuke on|off setting becuase that  
seems to mention something about how the screen is cleared indicating  
that the contents will be re-written using the  background collor.   I  
can't highlight or copy-past content to verify if this is the case.

So this is where I am and it is worse then my past two configurations  
without screen where either the screen would clear on exit or do  
nothing leving the emacs/less output visible and providing a prompt.

any help would be apreiciated..

Thanks!

Ed
