I paired my mouse with an Azeron. 99% of the time it’s way better than the keyboard. The other 1% is split between keyboard and controller.
Between the two though I much prefer keyboard/mouse over controller, but there are some games I would rather use a controller for. But as far as ergonomics go, I agree with you.
I’ve had this before a few times but can’t remember what the fix was.
Try hitting Enter or Ctrl+C A prompt may show up. If not try Alt+F7 that may take you to the GUI login.
Sorry I can’t be more help at the moment, I may be able to later if no one else jumps in.
