[gentoo-user] Strange Alt key behavior?

[Grant]

I send a system image of my laptop to various other laptops of the
same make and model which they use to operate.  I wrote a script for
this and it works great.  I've run into a situation where a particular
new (used) laptop works fine but the Alt+F2 shortcut to open the
program launcher in xfce4 doesn't work and I can't switch to VTs 1-3
with Ctrl+Alt+F1/F2/F3.  VT4 works but then VT7 doesn't bring back the
desktop.  I'm not sure what this is pointing to.  Any ideas?
