Stuck in xmonad with mod key not working - how to recover?

Question

I am trying NixOS, and have a problem with fairly basic configuration. Basically, I experimented with xkboptions in configuration.nix, and lost the xmonad mod key when I tried to switch alt and win keys.

Now, every time I boot, I am offered none+xmonad session, as I configured that intentionally. But, when I log in, I am stuck. Since mod is not working, I cannot quit xmonad to console, I cannot open terminal to try to recover...

I would know how to recover if I had a way to reach terminal, but I do not know how to do that. Is there some way to avoid entering xmonad on login (which is the default) and to just drop into the terminal without X?

Answer 1

You probably solved that already, but...

Ctrl+Alt+F1 to Ctrl+Alt+F6 will take you to a command line with no X booted screen on most Linux distributions.
