How to detach from a screen session from within a tmux session?

I've seen posts of how to detach from screen within screen and from tmux within tmux, but none of them worked for me.


screen and tmux use different prefix keys by default:

  • Ctrl+A for screen
  • Ctrl+B for tmux

Just detach from screen session by sending Ctrl+A, D. If you configured them both to use the same prefix, tmux will pass prefix the second time you press it.


To add on @atype answer. If the prefix key is same ie ctrl + A then you need to press A double time then D ie

ctrl + A + A + D
