I just started learning how to use tmux following this tutorial.
The problem is, what ever I type in (Ctrl-b c, or any other shortcut), nothing happens. Just nothing. I open tmux and there is a status bar in the lower part of my terminal that says
 0:bash*, but nothing I can do after that. I have checked, I don't have any tmux.conf files nor anything else and I thought it should work out of the box. I'm on ubuntu 12.04.
