Working inside a VirtualBox virtual machine. Installed Arch Linux using the Archinstall method. Chose KDE as the DE and SDDM as the greeting screen.

Managed to log in once, but after adding a language and rebooting, I didn't seem to be able to change the keyboard layout, making entering the correct password impossible. I have tried looking up how to switch the keyboard layout, but am coming up with nothing. What is the key combination to change the keyboard layout in SDDM?

Setting up a different virtual machine now.
