Re: tmux and screen restore

I figured it out.

I noticed that it worked correctly on the remote system until I started tmux. So, I moved .tmux.conf away. Bam, the problem went away. I moved it back and started commenting out lines in .tmux.conf. I finally found the culprit that way!!

Drum roll...

alternate-screen off

As soon as I turned commented it out, it started working. There was also this:

set -g  default-terminal "screen-256color".

I commented it out as well just in case. I'll put it back if I notice a problem with "screen", which is the terminal type tmux defaults too (seems like). Though, this was not the reason.

Thanks so much!!!

Gary, thanks for your response.

Are you sure &term matches "linux"?  

Yes, I'm sure because I do an echo within that "if" block. I also force it to be "linux", so the Home and End keys work properly. But I've tried other terminal types too. tmux has "screen-256color" by default on my system.

You might try setting &t_ti and &t_te unconditionally and see if  that helps.

No, unfortunately doesn't :( 

That said, I'm surprised that this doesn't "just work" for you. 

Me too

 

I am currently running vim in a tmux window over ssh.  The local terminal is GNOME Terminal 2.32.0.  The values of 't_te' and 't_ti' automatically set by vim are:

 

t_te=^[[?1049l

 

t_ti=^[[?1049h

What is your remote operating system? 

Debian Linux

 

What terminal are you running locally?

I'm connecting from under a VM running Peppermint. The terminal is set to xterm.

 

Before you override them, what does vim say the values of 'term', 't_te' and 't_ti' are?

^[[?1049l

^[[?1049h

 

Thanks again!

Are you sure &term matches "linux"?  "linux" is the value of TERM
set by a Linux console.  Most terminals set TERM to "xterm".  Tmux
sets TERM to "screen".  (Vim sets &term to $TERM if TERM is set.)

You might try setting &t_ti and &t_te unconditionally and see if
that helps.

am currently running vim in a tmux window over ssh.  The local
terminal is GNOME Terminal 2.32.0.  The values of 't_te' and 't_ti'
automatically set by vim are:

  t_te=^[[?1049l
  t_ti=^[[?1049h

What is your remote operating system?  What terminal are you running
locally?  Before you override them, what does vim say the values of
'term', 't_te' and 't_ti' are?
