Can't increase scrollback buffer size in tmux




Referring to this answer I tried increasing the buffer size using commands

set-option -g history-limit 10000
set -g history-limit 10000

but it does not work for me. I want to increase the buffer size of all the windows or at least the current window in tmux. I am opening the tmux session in Putty.

Note: I was trying to use the mouse scroll. I am able to scroll up using "prefix [" but not using the mouse

Some troubleshooting tools that helped me when I had this problem:


to quickly fill up the scrollback

tmux new-session

to make sure I was getting a new session

tmux show-options -g

to see if tmux actually had the right setting.

In my case, I was unknowingly attaching to previous tmux sessions, that were created before I increased the history-limit.
