Answer
Correct Answer: Alt+Function Key (for example, Alt+F1 through Alt+F6)
Explanation
Introduction / Context:Linux systems provide multiple text-mode virtual consoles (tty1, tty2, …) accessible directly from the keyboard. Administrators often switch consoles for troubleshooting or to access a different login without disturbing a current session.
Given Data / Assumptions:
- We are using the Linux virtual terminals (not a graphical terminal emulator).
- We want to switch between tty consoles, commonly tty1–tty6.
- Default key bindings apply.
Concept / Approach:
By default, switching between VT consoles uses the Alt key combined with a function key: Alt+F1 for tty1, Alt+F2 for tty2, and so forth. From within a graphical session, distributions often map Ctrl+Alt+F1..F6 to switch between VTs, but at the raw console, Alt+Fn is the standard.
Step-by-Step Solution:
Press Alt+F2 to move to tty2.Log in as needed.Return to tty1 with Alt+F1.On desktops, switching from GUI may require Ctrl+Alt+F keys depending on display manager configuration.Verification / Alternative check:
Check the active tty by running tty after switching. Review systemd’s getty units (e.g., systemctl status getty@tty2.service ) to confirm TTY availability.
Why Other Options Are Wrong:
- Ctrl+Function Key: usually ineffective alone at the console.
- Ctrl+Alt+Del: triggers a reboot request (or is disabled), not VT switching.
- Alt+a+w+Function Key: not a standard binding.
- None: incorrect because Alt+Fn is correct.
Common Pitfalls:
- Confusing GUI hotkeys (Ctrl+Alt+Fn) with console hotkeys (Alt+Fn).
- Some distributions remap ttys; verify which F-keys are active.
Final Answer:
Alt+Function Key (for example, Alt+F1 through Alt+F6).
