keyboard in wrong mode after VT switch from X

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.

Not a big issue.  Just sharing.
