I've been running Debian GNU/Linux for several years. Recently I gave Hurd a try by running Debian GNU/Hurd on a physical machine. It works fine, and I can get X running without problem.
The problem is, I cannot switch back to text terminals by Ctrl-Alt-F*. Before I start X, I can switch between text terminals with Alt-F*, but after X starts, I can only stay in X. I cannot switch to a text terminal using Ctrl-Alt-F* like I do in a Linux system.
I would like to know, if it is possible to switch to a text terminal, and if so, how do I do it?
