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.
