I usually work in desktop (X11) environment all the time, but recently I had to troubleshoot a problem with Xorg configuration and had to switch between X and a text console quite a bit. And quite frequently (but not always) the keyboard seemed to be in wrong mode after a switch. At least, that's how it appeared: most key presses wouldn't get through, but some (I think Enter) would have an effect. Switching to another text console and back always fixed the input.

I think I've seen this sort of thing being caused by incorrect
modifier key state - that is, it's acting as if ctrl and/or alt are
being pressed. If you get in this state again try pressing and
releasing modifier keys to see if that clears it up. If so, it's a bit
of an unfortunate workaround but at least will provide a hint for next
debugging steps.

Yes, that was it.
I've just repro-ed the issue and pressing Alt helped to restore the input.

That's really good to know;  I've seen this for years when I end a startx
session and get back to VT2 I always had to switch to VT1 and back before
Ctrl+d would work (or others) as I usually want to logout.

I'll give it a try in a few days (unless a panic happens sooner).

It never bothered me enough as it usually only get into this when I shutdown
my system for updates.
