How do I switch to a virtual terminal from the graphics screen -- the ordinary CTRL-ALT-F? keys do not work

[Jay F. Shachter]

How do I switch to a virtual terminal from the graphics screen (other than by first logging in, and then invoking the chvt command)? The ordinary CTRL-ALT-F? keys do not work. I also tried FN-ALT instead of CTRL-ALT, and it also did not work. I notice that once I am in a nongraphics virtual terminal (by logging in and then invoking the abovementioned chvt command) the function key combinations work, but that is a bogus procedure.

(It shouldn't matter, but I mention it in case it does, that I am using the Latin-American keyboard mapping.)

Thank you in advance for any and all replies.

[Winux Linux]

I tested
CTRL+ALT+F3 or F4 or F5

Is ok

Did you do it on a USB-connected detached keyboard, or on the native keyboard? After posting my initial inquiry, I rebooted the computer with a USB keyboard attached to it. I was then able to chvt to the nongraphic virtual terminals thru the CTRL-ALT-F? combination on the detached USB keyboard; but I still could not do it on the native keyboard.

If you are able to do it on your native keyboard, then perhaps we can blame my Latin-American keyboard mapping, but we will need to collect more data, maybe it is my Lenovo hardware that should be blamed. I would very much like to know -- and I hope that the readers of this discussion thread share my curiosity -- I would very much like to know how to switch to a nongraphics virtual terminal on my Winux system, other than by hunting down a USB keyboard to connect it to. As always, thank you in advance for any and all replies.
