From the "you learn something new every day" dept... I have managed to 
misplace my ttys after installing KDE4 on my Kubuntu machine.  Pressing 
Ctrl-Alt-F(1-6) puts my monitor to sleep.  F7 still brings me back.  And 
that's about what I know.  I can't seem to find much info by searching for 
this, but I'll admit I'm not sure what to search for.  Can anyone offer me 
some advice on how to start troubleshooting this?

thx-
pd
