Ctl+Alt+F2 does not work

Had to reinstall 22.04 on a laptop. Now for some reason, at the login screen, nothing happens if I do a Ctl + Alt +f2.

Well thats a first!

So none of the function numbers ctrl alt + 1 to 7 work?

I always use F2 on my other systems. On this laptop F4 did work. Drat, should have tried other function keys.
