61. Scrollback issue
* How can I make tmux use my terminal's scrollback buffer?
!
Normally, tmux enables the terminal's alternate screen. Most terminals (such
as xterm) do not save scrollback for the alternate screen.You might prefer
tmux to use the normal screen, so it uses your terminal's scrollback
buffer. This way, you can access the scrollback buffer as usual, for example
using the mouse wheel - although there is no guarantee output inside tmux will
always (or ever) be added to the scrollback.
!
You can make tmux use the normal screen by telling it that your terminal does
not have an alternate screen. Put the following in ~/.tmux.conf:
!
set -g terminal-overrides 'xterm*:smcup@:rmcup@'
