Tmux set -g mouse-mode on doesn’t work

tmux

I've been looking around and people say that putting

set -g mouse-mode on

should let you scroll through the terminal output when running tmux. However, after both putting this in my ~/.tmux.conf file and saying tmux set -g mouse-mode on when in a tmux session, nothing changes. When I scroll I still get outside of tmux like scrolling in vim with default settings.

Anyone know why this is?

So this option has been renamed in version 2.1 (18 October 2015)

From the changelog:

 Mouse-mode has been rewritten.  There's now no longer options for:
    - mouse-resize-pane
    - mouse-select-pane
    - mouse-select-window
    - mode-mouse

  Instead there is just one option:  'mouse' which turns on mouse support

So this is what I'm using now in my .tmux.conf file

set -g mouse on

Vim in tmux background color changes when paging

As explained here, disable Background Color Erase (BCE) by clearing the t_ut terminal option (run :set t_ut= in Vim and then press Control+L to refresh the terminal's display) so that color schemes work properly when Vim is used inside tmux and GNU screen.

Per the above link, BCE can be set in .vimrc by adding the following

if &term =~ '256color'
    " disable Background Color Erase (BCE) so that color schemes
    " render properly when inside 256-color tmux and GNU screen.
    " see also http://snk.tuxfamily.org/log/vim-256color-bce.html
    set t_ut=
endif

Macos – lose vim colorscheme in tmux mode

I had the same problem. Only difference was I am using solarize rather then molokai.

To fix the issue, I have set up an alias in ~/.bashrc:

alias tmux="TERM=screen-256color-bce tmux"

And set up the default-terminal option in ~/.tmux.conf:

set -g default-terminal "xterm"

Lastly, do $ source ~/.bashrc to load new alias.
