Scrolling in less in a byobu pane in terminal

  • 772

When I run less file.txt (for example) in a terminal, I can use the mouse wheel to scroll through file.txt.

When running less file.txt in a byobu pane, one of two things happens when I scroll with the mouse wheel:

If byobu mouse-mode is off, the entire terminal scrolls, pushing byobu itself off the screen and nothing is passed to less.

If byobu mouse-mode is on, then the pane enters scrollback mode with the [10/220] line counter in the top corner, and nothing is passed to less.

How do I configure byobu to send mouse events through to the pane in which I am scrolling?

I am using xfce4-terminal on Xubuntu 20.04.
