Slide 61 text

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@' Ref: tmux FAQ http://tmux.svn.sourceforge.net/viewvc/tmux/trunk/FAQ
