Virtual machine environments can behave differently from your regular desktop when it comes to keyboard shortcuts and input. Here are the most common keyboard-related issues and how to resolve them.
I can't access tty1 mode with Ctrl+Alt+F1. What do I do?
On laptops with shared function keys, Ctrl + Alt + F1 may trigger a system action like muting sound rather than switching to tty1 mode. Try the following:
- Use the FN key: Press Ctrl + Alt + FN + F1 instead.
- Use a terminal command: If your lab uses a Linux VM with a graphical interface, open a Terminal window and type: sudo login. This manually switches to tty1 mode.
Can I copy and paste into the VM?
No. The Skill Labs environment does not support copying and pasting content directly into the virtual machine console. All commands and lab content must be entered manually inside the VM.
Note: This is intentional. The hands-on entry of commands is part of the learning experience and helps reinforce the skills being practiced.
My keyboard input isn't working inside the VM at all. What do I try?
- Click directly inside the VM window to make sure it has focus before typing.
- Switch to Chrome or Edge if you are using Firefox. Firefox is known to cause keyboard input issues in VM environments.
- Clear your browser cache and relaunch the lab.
- Try launching the lab in Incognito or Private mode to rule out extension conflicts.
- If none of the above work, take a screenshot and contact Skill Labs Learning Support.
