I've been using tmux for a number of years, earlier today I thought I'd try byobu - to see what it's like. But now I can't get back to tmux. When I run tmux I end up back in boyobu. Does anyone know what's going on?
You need to kill the original tmux
server, that was started by the byobu
process.
You can do this using:
tmux kill-server
Full disclosure: I am the author and maintainer of byobu.
